4 Panel Multi Dip Card

4 Panel Drug Test Dip Cards

Two distinct 4-panel dip card configurations for different screening needs. The exclusive 4-Level THC Dip Card detects marijuana at four concentration thresholds simultaneously in a single device. The standard 4-panel configuration screens for Opiates, Cocaine, THC, and Methamphetamine from a single urine dip. CLIA Waived available. Bulk pricing from $0.49.

What Is a 4 Panel Drug Test Dip Card?

A 4 panel drug test dip card is a urine immunoassay device that screens for four substances simultaneously using a single urine dip, delivering results in 5 minutes. At 12 Panel Now, the 4 panel dip card category includes two fundamentally different products that serve different program needs. The 4-Level THC Dip Card is a single-substance test that uses four separate THC immunoassay strips calibrated to different concentration thresholds, giving the tester a concentration range reading rather than a binary positive-or-negative result. The standard 4 panel dip card is a four-substance test covering Opiates (OPI/300 ng/mL), Cocaine (COC/300 ng/mL), Marijuana (THC/50 ng/mL), and Methamphetamine (mAMP/1000 ng/mL) in a single device. These two products serve entirely different clinical and operational purposes despite both carrying the “4 panel” designation. As the manufacturer of the Serenity brand drug testing product line, 12 Panel Now produces both configurations under the same quality and accuracy standards, with the 4-Level THC card carrying a CLIA Waived classification for use in clinical settings. According to the SAMHSA Drug-Free Workplace Program, urine immunoassay screening at defined cutoff thresholds is the standard preliminary screening method for both federally mandated and non-mandated drug testing programs in the United States.

What Does a 4 Panel Drug Test Test For?

The answer depends entirely on which 4-panel configuration is selected, and this is the most important product selection decision in this category. The standard 4 panel dip card covers four distinct substance classes: Opiates (morphine and related opioids at 300 ng/mL), Cocaine (at 300 ng/mL), Marijuana/THC (at 50 ng/mL), and Methamphetamine (at 1000 ng/mL). This combination covers the four most commonly detected substances in non-federal workplace drug testing programs and is a practical baseline for employers, home testers, and compliance programs that do not need the breadth of a 5 or 10-panel format but do need multi-substance coverage. The 4-Level THC Dip Card tests for one substance only — marijuana/THC — but at four different concentration thresholds simultaneously (15, 50, 100, and 200 ng/mL), providing information that no standard single-threshold THC test can deliver. Buyers who search for a “4 panel drug test” expecting a four-substance panel and buyers who search for the same term while looking for the four-level THC card need to confirm which product matches their operational need before placing an order.

What Makes the 4-Level THC Dip Card Unique in the Drug Testing Market?

The 4-Level THC Dip Card is the only rapid urine drug test available that simultaneously detects marijuana metabolites across four distinct concentration thresholds — 15, 50, 100, and 200 ng/mL — in a single device and a single test event. No other standard or multi-panel urine drug test format produces this result. A standard THC strip at 50 ng/mL tells you whether the THC-COOH metabolite concentration in the specimen is above or below 50 ng/mL. The 4-Level THC Dip Card from 12 Panel Now tells you whether the concentration is below 15 ng/mL (negative on all four strips), between 15 and 50 ng/mL (positive on the 15 ng/mL strip only), between 50 and 100 ng/mL (positive on the 15 and 50 ng/mL strips), between 100 and 200 ng/mL (positive on the bottom three strips), or above 200 ng/mL (positive on all four strips). Each reading provides a concentration band that a single-threshold test cannot give. This matters operationally for programs where the concentration trend over time has clinical meaning. A patient in cannabis detoxification whose specimen reads above 200 ng/mL in week one, between 100 and 200 ng/mL in week two, and below 50 ng/mL in week three is demonstrating documented THC metabolite reduction that a 50 ng/mL binary test would miss entirely because all three results would read as positive with no indication of progress. The SKU for this product is SM-DOA-245 and it is available from $0.49 per test at wholesale volume.

How Do You Read the Results on a 4-Level THC Dip Card?

The 4-Level THC Dip Card produces four separate test regions on a single card, each calibrated to one of the four cutoff thresholds. As with all lateral flow immunoassay strips, a visible colored band in the test region (T) of each strip — however faint — indicates that the THC-COOH concentration in the specimen is below that strip’s cutoff (a negative result for that threshold). The absence of a colored band in the test region alongside a visible control band (C) indicates that the THC-COOH concentration is at or above that strip’s cutoff. Reading all four strips together produces the concentration band determination. If the 15 ng/mL strip shows no test line but the 50, 100, and 200 ng/mL strips all show test lines, the THC-COOH concentration is between 15 and 50 ng/mL. If only the 200 ng/mL strip shows a test line, the concentration is above 200 ng/mL. A control line must be visible on every strip for the test to be valid. An absent control line on any strip invalidates that strip’s result and requires retesting with a fresh device. Results must be read at the 5-minute mark and not after 10 minutes. Complete administration instructions are included in each individually packaged test.

Who Uses the 4-Level THC Dip Card and in What Settings?

The 4-Level THC Dip Card is used primarily by cannabis detoxification programs, rehabilitation centers, pain management clinics, and court-ordered supervision programs that need to track THC metabolite concentration trends over time rather than simply confirming presence or absence. According to Quest Diagnostics’ 2025 Drug Testing Index, marijuana maintained a 4.5% positivity rate in the general US workforce in 2024 and a 7.3% post-accident positivity rate, making it the single most commonly detected substance in American drug testing programs. For rehabilitation and treatment centers managing patients through cannabis detoxification, the 4-Level THC card provides documented evidence of metabolite reduction across four concentration bands during the weeks following cessation, giving clinical teams a rapid and affordable measure of detox progress without laboratory turnaround time. For pain management clinics monitoring patients whose prescribed pain management regimens require cannabis abstinence, the multi-level reading differentiates between incidental or historic exposure at the lower thresholds and active recent use at the higher thresholds. For drug court and probation programs where a participant’s cannabis use history is documented and tracked across multiple supervision appointments, the 4-Level card provides quantitative trend data from a rapid on-site device at a cost of $0.49 per test.

Is the 4-Level THC Dip Card Appropriate for Workplace Drug Testing?

Yes, particularly for employers in legal cannabis states that have moved to a more nuanced cannabis testing policy. In states including California, New York, New Jersey, Washington, Illinois, and others, legislation increasingly restricts employers from taking adverse employment action based solely on a positive THC test result for non-safety-sensitive positions. Employers operating in those jurisdictions who still wish to monitor cannabis use can use the 4-Level THC card to identify very high concentration results — consistent with recent active use — while distinguishing them from low-concentration results that may reflect historical or residual metabolite excretion unrelated to recent impairment. This is not a legally definitive impairment determination, and employers should consult employment counsel before using any drug test result to inform employment decisions in restricted jurisdictions. For safety-sensitive positions, post-accident testing, and reasonable suspicion testing where the federal 50 ng/mL threshold governs, the 50 ng/mL strip reading on the 4-Level card provides the same result as a standard THC strip while the additional thresholds provide supplemental concentration context. For employers who need only a binary 50 ng/mL THC result without additional concentration data, the single panel THC drug test strip is a more cost-effective choice.

Who Uses the Standard 4 Panel Drug Test Dip Card?

The standard 4 panel dip card covering OPI, COC, THC, and mAMP is used by employers, home testers, small compliance programs, and individuals who need multi-substance screening for the four most commonly misused substances without the cost of a 10 or 12-panel format. The OPI/COC/THC/mAMP combination covers opiates, cocaine, marijuana, and methamphetamine, which collectively represent the core substance categories most relevant to workplace safety incidents, roadside impairment, and home and family monitoring situations. The four-substance format sits between the single-substance strip and the five-substance 5-panel format that represents the federal SAMHSA baseline for mandated workplace programs. Programs that do not operate under federal drug-free workplace mandates — which require a minimum 5-panel configuration — and whose substance risk profile is adequately covered by opiates, cocaine, cannabis, and methamphetamine will find the 4-panel format a cost-effective and appropriately scoped solution. Sober living homes, family members monitoring a relative in early recovery, and small employers in non-DOT industries are the most common buyer segments for the standard 4-panel dip card format. The standard 4-panel is also available as an oral swab configuration for programs that prefer saliva collection over urine specimen handling.

What Is the Difference Between the 4 Panel Dip Card and a 4 Panel Drug Test Cup?

Both the 4 panel dip card and a 4 panel drug test cup use the same lateral flow immunoassay technology and deliver equivalent screening accuracy for the same four substances. The operational difference is in collection format, documentation, and cost. A drug test cup integrates specimen collection and testing into one sealed container where the donor urinates directly into the cup and results are read through the test windows without opening the container, maintaining specimen integrity and reducing handling risk. A dip card requires a separate clean collection container from which the card’s test strips are dipped into the specimen for 10 to 15 seconds. The dip card format is less expensive per test and better suited for settings where documentation of the test strip readings is needed through the photocopy-compatible result windows. The cup format is better suited for settings where specimen handling hygiene, tamper-evident collection, and integrated temperature strip validity confirmation are operational priorities. 4 panel drug test cups are available alongside dip cards at 12 Panel Now, giving programs the flexibility to choose the collection format that best matches their administration environment.

Why Choose 4 Panels Instead of a 5 or 10-Panel Format?

The 4-panel format is the right choice when the program needs multi-substance coverage for the four most common non-PCP substances without the federal 5-panel mandate, or when cannabis has been removed from the screening policy and three stimulant and opiate substances are all that remains relevant. The federally mandated SAMHSA 5-panel covers THC, cocaine, amphetamines, opiates, and PCP. Many non-federal employers in 2025 and 2026 have moved to a 4-panel “no-THC” configuration that removes marijuana from the panel in response to state cannabis legalization laws, retaining cocaine, opiates, and methamphetamine as the core screening substances. The legal landscape for employer cannabis testing has shifted meaningfully since 2020, with California, New York, New Jersey, Washington, and other states enacting various restrictions on adverse action based on positive THC results for non-safety-sensitive roles. For those employers, a 4-panel configuration that excludes THC entirely — or for programs that need only the four OPI/COC/THC/mAMP substances — the 4-panel dip card is the most cost-efficient and appropriately scoped format available. Programs that need the PCP analyte, benzodiazepines, oxycodone, barbiturates, or other prescription drug monitoring should move to the 5 through 19 panel dip card formats available at 12 Panel Now.

Does the 4 Panel Dip Card Detect Fentanyl?

No. Neither the standard 4 panel dip card (OPI/COC/THC/mAMP) nor the 4-Level THC Dip Card detects fentanyl. The OPI strip on the standard 4-panel detects morphine, codeine, and heroin metabolites at 300 ng/mL but does not detect fentanyl, which has a fundamentally different molecular structure and requires a dedicated FEN immunoassay strip to produce a result. The HHS Federal Register notice of January 2025 confirmed that fentanyl was added to the authorized federal testing panel effective July 7, 2025, reflecting the federal recognition that fentanyl is not detected by standard opiate immunoassay strips. Programs that need fentanyl detection alongside their 4-substance baseline should consider adding the single panel fentanyl dip card as a targeted add-on to the standard 4-panel at $0.49 per test, or upgrading to a higher-panel dip card configuration that includes a dedicated FEN strip. This is one of the most operationally significant gaps in any drug testing program running a 4-panel or lower format without a supplemental fentanyl-specific strip.

What Are the Detection Windows for the Standard 4 Panel Dip Card?

Detection windows for the standard 4-panel dip card vary by substance: THC is detectable for 3 to 30 days, opiates for up to 3 days, cocaine for 2 to 4 days, and methamphetamine for 2 to 4 days in urine. THC (marijuana) has the longest and most variable window because THC-COOH, the primary urinary metabolite, is fat-soluble and accumulates in body fat tissue, releasing slowly over time in chronic users. Occasional users typically test positive for 3 to 7 days. Heavy chronic daily users can test positive for 30 days or more. The OPI strip at 300 ng/mL detects morphine, codeine, and heroin metabolites for up to 3 days following use. Cocaine metabolites are typically detectable for 2 to 4 days. Methamphetamine at the 1000 ng/mL cutoff on this panel is detectable for 2 to 4 days. These detection windows reflect the advantage of urine over oral fluid testing for multi-day historical documentation. For the 4-Level THC Dip Card specifically, detection windows align with the THC ranges above — but a result that falls between 15 and 50 ng/mL rather than above 200 ng/mL reflects a specimen that is in the declining phase of metabolite excretion, typically consistent with use that occurred several days to several weeks earlier depending on the individual’s frequency of use and body composition. The NIH reference on cannabis pharmacokinetics documents the high inter-individual variability in THC metabolite clearance, which is the primary reason that no single detection window figure is accurate for all users.

How Accurate Is the 4 Panel Drug Test Dip Card?

Both the 4-Level THC Dip Card and the standard 4-panel dip card deliver 99% accuracy across their respective analytes when administered correctly. The CLIA Waived classification on the 4-Level THC card confirms FDA clearance and validation for clinical use by minimally trained operators. Accuracy depends directly on following the administration protocol: dipping the card for 10 to 15 seconds, capping the strips immediately after dipping, laying the card flat on a clean non-absorbent surface, and reading results at exactly the 5-minute mark. Allowing the urine to touch the plastic card housing above the maximum dip line produces flooding and invalid results. Reading after 10 minutes produces unreliable results regardless of product quality. All presumptive positive results from either product must be confirmed by a certified laboratory using GC-MS or LC-MS/MS methodology before any employment, clinical, or compliance consequence is applied. The SAMHSA Drug-Free Workplace FAQ confirms that rapid immunoassay screening results are preliminary only, and laboratory confirmation is mandatory before any consequential action is taken based on a positive screening result.
