12 Panel Now is the creator and manufacturer of the Serenity® 12 panel drug test. Producing high-quality variations of every 12 panel configuration each available as a CLIA-waived, FDA-cleared test for diagnostic and workplace use, and as a Forensic Use Only (FUO) test for non-diagnostic programs. That gives you one manufacturer-direct source for whichever version your program requires, at bulk pricing.
Every 12 panel drug test we make comes in both compliance versions, so buyers choose the right one for their setting:
12 Panel Drug Test By 12 Panel Now | Available in Multiple Format and Variations | CUP | DIPS | SWABS | FUO | CLIA & FDA
A Forensic Use Only (FUO) 12 panel drug test is a urine cup labeled for non-diagnostic screening—used by probation and parole, law enforcement, rehabs, and individuals. As the creator of the Serenity® 12 panel drug test, 12 Panel Now produces forensic variations of every 12 panel drug test and 12 panel drug test cup, often with expanded panels (adding analytes like EtG, fentanyl, and others) that aren’t offered in CLIA-waived versions. The same manufacturer-direct quality is built specifically for forensic workflows.
Who Uses FUO 12 Panel Drug Tests
Probation, parole, and drug courts
Law enforcement & correctional facilities
Rehab / treatment centers and sober living
At-home and self-testing
CLIA-Waived vs. FUO — Which Do You Need?
Choose a CLIA-waived 12 panel drug test for diagnostic or workplace use. Choose a FUO 12 panel drug test for forensic, non-diagnostic programs. 12 Panel Now manufactures both versions of every configuration, allowing you to order the right 12 panel drug test from a single trusted manufacturer.
CLIA-waived means the FDA has determined a test is simple enough to carry a negligible risk of erroneous results, permitting its use outside a certified laboratory by personnel without formal laboratory training. Your testing site still needs a CLIA Certificate of Waiver from CMS before running waived tests.
FDA-approved (more precisely, FDA-cleared under 510(k)) means the device has been reviewed and found substantially equivalent to a legally marketed predicate device for its stated intended use.
CLIA Waived vs Forensic Use Only (FUO)
Our catalog contains both CLIA-waived and Forensic Use Only devices, and they are not interchangeable. We would rather state this plainly than let a buyer discover it during an inspection.

If your program falls under CLIA regulation — clinics, physician offices, treatment centres billing for testing — you must order a CLIA-waived configuration. Every product page states its status. If you are unsure which applies to your setting, contact us before ordering rather than after.
Accuracy & Confirmation Testing
12 panel drug tests are 97–99% accurate against laboratory confirmation when read at the stated cutoffs within the correct time window. Accuracy degrades measurably when devices are read after 10 minutes, used below 59°F or above 86°F, dipped past the MAX line, or read while held upright rather than laid flat.
Every rapid immunoassay device is a preliminary screening test.
A positive screening result does not establish impairment, intoxication, quantity used, or time of use. Any presumptive positive intended to support an employment, clinical, legal, or custodial decision must be confirmed by gas chromatography/mass spectrometry (GC/MS) or liquid chromatography–tandem mass spectrometry (LC-MS/MS) at a certified laboratory.
Employers should verify their program against applicable federal, state, and local requirements before adopting any configuration. Where a workplace program falls under U.S. Department of Transportation rules, only DOT-authorised panels, collectors, and procedures may be used — our devices are not DOT-authorised substitutes.

Wholesale, Reseller & Drop-Ship Programs
We supply drug test kits in bulk to distributors, occupational health providers, treatment centres, staffing agencies, corrections facilities, and online resellers. Wholesale drug test pricing is available across the full catalog, not just 12 panel devices.
Wholesale accounts — tiered volume pricing on bulk drug tests across all panel counts and formats
Reseller programs — for retailers and online sellers stocking drug test cups in bulk
Drop shipping — we ship directly to your customer under your account, with no minimum handling on your side
Standing orders — scheduled recurring shipments for programs with predictable monthly volume
OEM, Private Label & Custom Configurations
Because we manufacture the Serenity™ line rather than reselling another brand, we can build configurations that do not exist in the standard catalog. If your program needs a specific combination of analytes and cutoffs, we can produce it.
Private label — your branding on cup, dip, and swab devices and packaging
Custom analyte configurations — specify the exact drug classes and cutoffs your program requires
OEM manufacturing — full production runs to your specification
Custom cutoffs — for example OPI at 2000 ng/mL instead of 300 for federal-style programs
Why Buy 12 Panel Drug Test From 12 Panel Now
We manufacture and distribute the Serenity™ range directly, cups, dip cards, and oral fluid devices, rather than reselling another company’s product. That means wholesale pricing without an added margin layer, custom configurations that do not exist in standard catalogs, and direct answers about what is actually on each device.
12 Panel Now manufactures and distributes the Serenity™ range of 12 panel drug tests in all three device formats, urine cups, dip cards, and oral fluid swabs, from $1.19 per test, with free shipping on 100+ units and same-day dispatch. Need fewer analytes? See our 4 to 11 panel cups. Need broader coverage? Step up to 13 to 16 panel cups or 17 to 28 panel cups. Ordering at volume? See wholesale pricing.
A 12 panel drug test screens for the SAMHSA-5, amphetamines, cocaine, marijuana, opiates, and PCP, plus seven additional classes, commonly benzodiazepines, barbiturates, buprenorphine, methadone, oxycodone, MDMA, and one variable twelfth analyte such as fentanyl, EtG alcohol, K2, or TCA.
There is no single universal 12 panel drug test list. This is the most misunderstood fact in the category, and it matters commercially: two devices both labelled “12 panel” can return different results on the same specimen because their twelfth strip targets a different substance. Always check the analyte list on the product page before ordering, not the panel count.

Note on OPI cutoffs: the 300 ng/mL cutoff is more sensitive and will flag poppy-seed consumption and low-dose codeine. The 2000 ng/mL cutoff is the federal workplace standard and is designed to exclude dietary sources. Choose deliberately. This single number changes your positive rate more than any other variable on the device, and it is available as a custom cutoff on wholesale orders.
Every cup below is a Serenity Cup®, manufactured and distributed by 12 Panel Now, with a double click-top lid, built-in temperature strip, and five-minute read time. Variable analytes, the ones that distinguish each SKU, are shown in bold. All 90ml bodies are also listed in economy cups.
This is the reference 12 panel, the SAMHSA-5 plus seven. Because it carries PCP, it is the configuration most often specified when an employer’s drug policy was originally drafted around federal testing language, which makes it the default for pre-employment screening programs. Available as the 120ml SM-CDOA-6125 from $1.49 or the 90ml SM-CDOA-6125-90 from $1.29. The dip-card equivalent is SM-DOA-6125.
Swaps PCP for tricyclic antidepressants. Used in psychiatric and behavioural-health settings where TCA adherence and overdose risk are more clinically relevant than PCP exposure. Also useful in geriatric and pain populations where TCAs are commonly prescribed. View SM-CDOA-7125 from $1.49. For TCA alongside gabapentin, step up to a 14 panel cup.
K2 does not trigger the THC strip. Synthetic cannabinoids are structurally unrelated to delta-9-THC and require their own antibody entirely. This is why corrections, probation, and residential treatment programs specify a K2 configuration. Synthetic cannabinoids are the single most common method of defeating a standard 12 panel. Available as the 120ml SM-CDOA-3125-FUO from $1.49 or the 90ml SM-CDOA-3125-FUO-90 with OPI/300 from $1.29. To add ketamine alongside K2, see our 16 panel cups.
The fastest-growing line in the catalog, and the only 12 panel configuration covering both alcohol and fentanyl. ETG detects the alcohol metabolite ethyl glucuronide for up to 80 hours, meaning a Monday-morning test catches Saturday-night drinking, which a breathalyzer cannot. FEN at 20 ng/mL covers both pharmaceutical and illicit fentanyl, making this family the standard choice for MAT and opioid treatment programs.
The 4125 family trades BUP for BAR and ships with PH/SG/CR validity checks as standard. Choose it when specimen integrity is a live concern in your population.
Four variable analytes simultaneously: kratom, K2, ETG, and fentanyl. This is the widest emerging-substance coverage available in a twelve-strip format, and it exists because programs kept reporting clean 12 panels on donors who were visibly impaired. If your population uses kratom or synthetic cannabinoids, a standard panel is functionally blind. View SM-CDOA-9125EFK-FUO from $1.49. For harm reduction and street-supply surveillance, step up to 22 and 28 panel cups.
12 Panel Drug Test Dip Card | Complete Range & Configurations
A 12 panel drug test dip card is a flat plastic device holding twelve test strips that is dipped into a separately collected urine specimen for 10 to 15 seconds, then laid flat to develop. It screens the same twelve drug classes as a 12 panel cup at a lower unit cost, from $1.19, but requires its own collection container.
Dip cards are the volume buyer’s format. Because the test device and the collection container are decoupled, you buy exactly the container you need, and the card itself ships smaller, stores flatter, and costs less. The trade-off is one additional handling step and a temperature strip that depends on the container rather than being built into the device. Lower panel counts are available as 4 panel THC, 6 panel MAT, 7 panel and 8 panel dip cards. Higher counts are available as 17 panel, 18 panel and 19 panel dip cards.
Dip Card vs Cup | The Real Cost Comparison

Dip cards win decisively when you already stock validated containers in bulk, when storage space is constrained, or when you are running very high volumes and discarding negatives immediately. Cups win when you buy containers at retail, need temperature verification, or may send specimens for confirmation. Compare 90ml economy cups before deciding, since they close most of the price gap.
The dip-card mirror of the SM-CDOA-6125 cup: identical twelve analytes, identical cutoffs, $0.30 cheaper per unit. The natural pairing for programs that already run the 6125 cup. Keep cups for chain-of-custody collections, switch to dips for routine in-house screening. View SM-DOA-6125 from $1.19. Step down to an 8 panel dip card if PCP and barbiturates are not required.
Adds fentanyl at 20 ng/mL alongside the three-way adulterant check. Because dip cards are collected into an open container, they carry inherently more adulteration exposure than a sealed cup. The PH/SG/CR strips close most of that gap and are strongly recommended for any dip-card program without directly observed collection, particularly in corrections and probation settings. View SM-DOA-8125AD3-FUO from $1.19.
The widest dip-card configuration available at twelve panels: alcohol metabolite, fentanyl, and tramadol together, plus full validity checking. Built for pain-management and medication-assisted treatment programs where tramadol adherence and alcohol use are both clinically relevant. Tramadol is worth calling out specifically. It does not reliably trigger the standard opiate strip, so without a dedicated TRA strip it goes undetected. View SM-DOA-8125AD3 from $1.19. To add gabapentin alongside tramadol, step up to a 17 panel dip card.
How to Use a 12 Panel Dip Card
Collect urine into a clean specimen container. Bring both container and card to room temperature (59 to 86°F).
Remove the cap from the dip card, exposing the twelve absorbent strips.
Dip vertically for 10 to 15 seconds. Do not submerge past the MAX line. Flooding the membrane is the number-one cause of invalid results.
Remove, replace the cap, and lay the card flat on a clean, non-absorbent surface. Reading a card held upright causes reagent to run and produces false readings.
Read at 5 minutes. Do not interpret after 10 minutes.
Interpretation is identical to a cup: any visible test line equals negative.
A 12 panel saliva drug test screens twelve drug classes in oral fluid using an absorbent collection pad held in the donor’s mouth for 3 to 5 minutes. Because collection is directly observed, adulteration is nearly impossible. Detection windows run 12 to 48 hours, much shorter than urine cups, making saliva the correct choice for recent-use and impairment questions.
Oral fluid testing answers a fundamentally different question from urine. Urine tells you whether someone used in the last several days. Saliva tells you whether someone used recently enough that the parent drug is still circulating, which correlates far more closely with present impairment.
When a Saliva Drug Test Beats Urine
Post-accident and reasonable-suspicion testing. You need to know about the last few hours, not last Tuesday.
No restroom facility available. Roadside, jobsite, warehouse floor, field, or mobile collection.
Gender-neutral collection. No same-sex collector requirement and no privacy suite to build or staff.
Shy bladder. No three-hour waiting period, no hydration protocol, no refusal-to-test disputes.
Adulteration-prone populations. There is nothing to substitute, dilute, or smuggle into the collection, unlike an open-container dip card collection.
Speed. Total collection time is 3 to 5 minutes with no bladder-dependent delay.
All 12 Panel Saliva Test Configurations
Oral fluid cutoffs are much lower than urine cutoffs because drug concentrations in saliva are lower. A 40 ng/mL THC saliva cutoff is not “less strict” than a 50 ng/mL urine cutoff. The two measure different matrices and are not comparable.
The full-coverage saliva device. Retains both THC and PCP while adding fentanyl. The 40 ng/mL oral fluid THC cutoff detects recent use only, roughly 12 to 24 hours, which is exactly what an impairment-based policy requires. View SMSPD-3126F-EUO from $1.49. For a multi-day lookback on the same analytes, use the SM-CDOA-9125AD3-FUO cup.
Pen-style format with an on-board alcohol strip reading at approximately 0.02% BAC equivalent. Unlike urine ETG, saliva ALC reflects current intoxication rather than past consumption, making this the correct device for reasonable-suspicion and return-to-duty testing, where present impairment is the legal question being asked. View SMSPD-3126A-EUO from $1.39. For an 80-hour alcohol lookback instead, use the SM-CDOA-9125-90 ETG cup.
Drops THC to accommodate synthetic cannabinoids, alcohol, and fentanyl simultaneously. Purpose-built for programs operating where recreational cannabis is legal and THC results are no longer actionable, but K2 and fentanyl very much are. View SMSPD-4126AFK-EUO from $1.39. The urine equivalent for K2 monitoring is the SM-CDOA-3125-FUO cup.
Same rationale as above, with MDMA occupying the position instead of K2. View SMSPD-7126AF-FUO from $1.39.
No-THC Configurations & Legal Cannabis
Employers in recreational-legal states face a specific problem: a positive THC result they cannot lawfully act on still creates a documented record, a conversation, and potential liability. Several states now restrict adverse employment action based on off-duty cannabis use, and a positive urine THC result says nothing about on-duty impairment in any case.
The no-THC saliva configurations, SMSPD-4126AFK-EUO and SMSPD-7126AF-FUO, deliver a full twelve panels of coverage while simply not testing for a substance you cannot act upon. That position is reallocated to fentanyl, alcohol, K2, or MDMA, all of which remain actionable everywhere. Verify your own state and local requirements before adopting this approach, and see our pre-employment program guidance.
How to Use a 12 Panel Saliva Drug Test
No food, drink, gum, or tobacco for 10 minutes before collection. This is by far the most common cause of invalid saliva results.
Have the donor move the collection pad around the mouth, inside both cheeks and under the tongue, for 3 to 5 minutes, or until the saturation indicator turns blue.
Insert the saturated pad into the device body and press firmly until it seats.
Read at 10 minutes. Saliva devices develop more slowly than urine devices. Reading at 5 minutes produces false positives.
Interpretation is identical: any visible test line equals negative.
All three formats screen the same twelve drug classes. They differ in specimen type, detection window, cost per completed collection, facility requirements, and chain-of-custody suitability. Cups suit chain of custody, dip cards suit high-volume budget screening, and saliva suits recent-use and field collection.

12 Panel Cup vs Dip Card
Cups and dip cards test identical urine analytes at identical cutoffs. The cup integrates collection, testing, and transport into one sealed device with a built-in temperature strip. The dip card separates them and costs less per device, but requires a container you must buy and a temperature strip you may not have.
Verdict: if a specimen may ever be confirmed, disputed, or litigated, use a cup. If you are screening at high volume in-house and discarding negatives on the spot, dip cards deliver better economics, provided you price the container in honestly before deciding. Also compare 90ml economy cups, which cut the gap to $0.10.
12 Panel Cup vs Saliva Swab
Cups detect drug use over 2 to 7+ days from urine. Saliva swabs detect 12 to 48 hours from oral fluid. Cups require restroom facilities and same-sex observation to guard against adulteration. Swabs are directly observed, gender-neutral, and can be collected anywhere in under five minutes.
Verdict: these test different questions, and framing one as better than the other is a mistake. “Has this person used in the past week?” is a urine question. “Is this person impaired right now, and can I collect on a jobsite in four minutes?” is a saliva question. Post-accident programs should stock both formats and choose per incident.
12 Panel Dip Card vs Saliva Swab
Dip cards are the lowest-priced device at $1.19 and detect multi-day urine use. Saliva swabs start at $1.39 but eliminate container costs, facility requirements, and adulteration risk entirely. Dips need a restroom and a container. Swabs need neither.
Verdict: dip cards win on device price alone. Saliva wins on true cost per completed collection once you account for containers, facility time, shy-bladder delays, and re-collections.
A 12 panel drug test screens a single urine sample for 12 of the most commonly misused drugs at once, each at an industry-standard cutoff (ng/mL). The Serenity® 12 panel drug test cup detects:
Every kit is fully self-contained: a leak-proof urine cup, built-in temperature strip and result label no extra supplies needed. Need more coverage? Add FEN, EtG or K2, or step up to a 13–28 panel drug test cup.
A 12 panel urine drug test detects most substances for 2 to 4 days after use, with cannabis extending to 30 days in chronic users and ETG alcohol reaching 80 hours. A 12 panel saliva test detects 12 to 48 hours. Detection windows vary with dose, frequency, metabolism, body composition, and hydration.

Why THC is the outlier.
THC is fat-soluble and accumulates in adipose tissue, releasing slowly over weeks. A daily user can test positive up to 30 days after stopping, while a first-time user may clear in 2 to 3 days. No other analyte on a 12 panel behaves this way, and it is the single largest source of disputed results.
These are screening-level estimates intended for program planning. They are not clinical or forensic determinations, and no detection window should be presented as evidence of when a substance was used.
Note:
Detection windows are general estimates provided for educational purposes only and vary by individual. They do not guarantee when a substance will or will not be detected.
Our 12 panel drug test cups are 99% accurate when used as directed. Immunoassay screening is a presumptive test: any non-negative result should be confirmed by a laboratory using GC-MS or LC-MS before being treated as a confirmed positive. Accuracy depends on following the instructions — collecting a valid sample, reading at 5 minutes, and checking the control line.
A standard 12 panel drug test does not include alcohol. To screen for alcohol, choose a cup that adds EtG (ethyl glucuronide) — such as the 12 Panel Cup with EtG.
› Base 12-panel = no alcohol panel
› EtG detects alcohol use for up to 80 hours — far longer than a breathalyzer
Because 12 Panel Now makes the Serenity® cup, you buy factory-direct. A 12 panel drug test kit starts as low as $1.39 per cup, dropping further at bulk volumes.
A standard 12 panel drug test screens urine for the following 12 substances.
Each has an established cutoff level (in nanograms per milliliter) — the concentration at or above which the result is reported as positive:

Note:
Cutoff values above are the common industry configuration — confirm each against the Serenity® spec sheet, since some panels use different levels (e.g., AMP/MET 1000, COC 300).
Read each of the 12 test strips after 5 minutes. Any visible colored line next to a drug — even a faint one — means the result is negative for that drug. A missing line means a presumptive positive. If no control (C) line appears, the test is invalid and should be repeated. (See our full step-by-step guide: How to Read a 12 Panel Drug Test. The Serenity® 12 panel drug test cup detects:
Every cup includes a built-in temperature strip to help confirm the sample is valid and unadulterated. Read the temperature within 4 minutes of collection; a fresh urine sample should register within roughly 90–100°F (32–38°C). A reading outside that range can indicate a tampered or substituted sample.

A 12 panel drug test screens a single urine sample for 12 of the most commonly misused drugs at once, each at an industry-standard cutoff (ng/mL). The Serenity® 12 panel drug test cup detects:
Every kit is fully self-contained: a leak-proof urine cup, built-in temperature strip and result label — no extra supplies needed. Need more coverage? Add FEN, EtG or K2, or step up to a 13–28 panel drug test cup.
Detection windows vary by drug, dosage, metabolism, body composition, and frequency of use. Most drugs remain detectable in urine for approximately 1 to 7 days, while chronic marijuana use may be detectable for several weeks. A 12 panel drug test cannot determine exactly when a drug was taken—only whether it is present above the cutoff level.

“Illicit drugs” are controlled or illegal substances used outside legitimate medical direction — the substances a 12 panel drug test is designed to detect.
› Illegal drugs such as cocaine, methamphetamine, heroin and MDMA
› Misused prescriptions such as oxycodone, benzodiazepines and buprenorphine
› Emerging substances like fentanyl, K2/spice and kratom (screened on expanded panels)
No, a standard 12 panel drug test does not test for alcohol. Most 12 panel drug tests are designed to detect commonly abused drugs such as amphetamines, cocaine, marijuana (THC), opiates, methamphetamine, benzodiazepines, barbiturates, methadone, PCP, oxycodone, MDMA, and propoxyphene (depending on the panel configuration). Alcohol requires a separate alcohol screening test because ethanol leaves the body much faster than most drugs.
If alcohol testing is required, employers, treatment programs, or legal agencies typically use an EtG (Ethyl Glucuronide) urine test, a breath alcohol test, or blood alcohol testing. Some drug test cups combine a 12 panel drug test with an EtG alcohol test so both drugs and recent alcohol consumption can be screened using a single urine sample.
No. Kava does not normally appear on a standard 12 panel drug test because its active compounds, called kavalactones, are not included in routine workplace drug screening.
Why doesn’t kava show up?
Kava is a plant-based supplement made from the roots of Piper methysticum. Unlike opioids, amphetamines, cocaine, THC, or benzodiazepines, its active ingredients have a completely different chemical structure.
Key points
Standard 12 panel tests do not screen for kava.
Kava is not a federally scheduled drug in the United States.
Routine employment drug tests are not designed to detect kavalactones.
Detecting kava requires specialized laboratory testing, which is rarely ordered.
Can kava cause a false positive?
Modern laboratory confirmation methods make false positives uncommon. While isolated reports exist with older immunoassays, confirmation testing such as GC-MS or LC-MS/MS generally rules out incorrect results.
Usually no. Ritalin (methylphenidate) and Focalin (dexmethylphenidate) are not included on most standard 12 panel drug tests. Although both medications are prescribed to treat Attention-Deficit/Hyperactivity Disorder (ADHD), they are chemically different from amphetamines and typically do not trigger the amphetamine screening panel.
Why don’t they appear on a standard 12 panel drug test?
Most workplace drug tests are designed to detect drugs with a high potential for misuse that are commonly required by employers, courts, and treatment programs.
Ritalin and Focalin belong to the methylphenidate class rather than the amphetamine class, so standard immunoassay drug screens generally do not identify them.
Key facts
Ritalin = methylphenidate
Focalin = dexmethylphenidate
Neither medication is usually included in a routine 12 panel drug screen.
They generally do not cause a positive amphetamine result because of their different chemical structure.
A laboratory can detect methylphenidate if a specific methylphenidate assay is ordered.
When could they be tested?
Healthcare providers, substance use treatment programs, or forensic laboratories may order specialized testing when monitoring prescription compliance or suspected misuse. A standard 12 panel drug test does not normally detect Ritalin or Focalin. Detecting either medication requires a dedicated laboratory test specifically designed for methylphenidate.
Routine workplace drug testing focuses on recreational and commonly misused prescription drugs rather than performance-enhancing substances.
Drugs that are NOT typically included
Testosterone
Anavar (Oxandrolone)
Dianabol (Methandrostenolone)
Winstrol (Stanozolol)
Deca-Durabolin (Nandrolone)
Trenbolone
Primobolan
Equipoise
How are steroids tested?
Testing for anabolic steroids usually requires:
Blood testing
Urine testing using GC-MS or LC-MS/MS
Hormone ratio analysis
Sports anti-doping laboratory testing
Professional sports organizations and anti-doping agencies often use these specialized methods because standard workplace drug screens are not designed to detect anabolic steroids.
Most of these medications do not appear on a standard 12 panel drug test. Routine drug screens only test for specific drugs and drug classes, so many commonly prescribed medications are excluded.
A standard 12 panel drug test focuses on drugs commonly required for:
Pre-employment testing
Random workplace screening
Court-ordered drug testing
Substance use treatment monitoring
Prescription medications outside those categories generally require individual laboratory assays.
Most of these medications will not appear on a standard 12 panel drug test. If testing is required, a healthcare provider or employer must request a specific laboratory analysis.
It is an instant/rapid test — results in roughly 5 minutes, no lab required.
Positive immunoassay results are commonly confirmed using:
Gas Chromatography-Mass Spectrometry (GC-MS)
Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS)
These methods help distinguish true positives from false positives. If your 12 panel drug test includes MDMA, recent Molly or Ecstasy use can produce a positive result.
No. LSD (lysergic acid diethylamide) is not included on most standard 12 panel drug tests.
Why isn’t LSD included?
LSD is active in extremely small doses and requires highly specialized laboratory techniques for accurate detection. Routine workplace drug tests are designed to identify more commonly abused substances such as THC, cocaine, amphetamines, opioids, and benzodiazepines.
Important facts
Standard 12 panel tests do not screen for LSD.
Specialized laboratory testing is required.
Detection usually requires advanced analytical methods.
LSD testing is uncommon in routine employment screening.
A standard 12 panel drug test will not normally detect LSD unless a separate LSD test has been specifically ordered.
These compounds are not part of routine workplace drug screening panels.
Can kratom be detected?
Yes—but only if the laboratory specifically tests for it.
Specialized testing may be ordered by:
Pain management clinics
Drug rehabilitation programs
Probation departments
Forensic laboratories
Will kratom trigger an opioid test?
Generally no.
Although kratom interacts with opioid receptors, its chemical structure differs from morphine, codeine, heroin, and oxycodone. Most 12 panel drug tests do not detect kratom, but specialized laboratory assays can identify kratom metabolites when specifically requested.
Usually no. Tramadol is not detected by most standard 12 panel drug tests because it has a different chemical structure than traditional opiates. Although tramadol is an opioid analgesic, standard opiate immunoassays are primarily designed to detect drugs such as:
Morphine
Codeine
Heroin metabolites
Tramadol often requires its own dedicated screening panel.
When can tramadol be detected?
A laboratory can identify tramadol when:
A specific tramadol assay is ordered.
An expanded drug testing panel includes tramadol.
GC-MS or LC-MS/MS confirmation testing is performed.
Can tramadol cause a positive opioid test?
Generally no. However, test performance depends on the specific assay and cutoff values used by the laboratory. Positive screening results should always be confirmed with laboratory testing before making clinical, employment, or legal decisions.
A standard 12 panel drug test does not normally detect tramadol. If tramadol monitoring is needed, use a test panel or laboratory assay that specifically includes tramadol.
Usually no. Standard 12 panel drug tests do not detect Suboxone unless buprenorphine is included as a separate test panel. Suboxone contains buprenorphine and naloxone, and buprenorphine requires a dedicated assay because it is chemically different from traditional opioids such as morphine, codeine, or heroin.
If an employer, healthcare provider, or treatment program needs to monitor Suboxone use, they should order a buprenorphine drug test or use a 13 panel, 14 panel, or customized drug test cup that specifically includes buprenorphine (BUP). Without a buprenorphine panel, a person taking Suboxone will generally receive a negative result for that medication on a standard 12 panel drug test.
