What is Methadone?

Doctors prescribe methadone for treating opioid addiction. This synthetic opioid agonist acts on the opioid receptors in the brain that are activated by opioids like morphine, heroin, and opioid-based pain medication.

However, unlike heroin, morphine, or opioid pain relievers, methadone acts slowly. Additionally, it does not produce euphoria in a person with an opioid disorder.

What Are the Side Effects of Methadone?

Methadone is an effective and cheaper option for the treatment of opioid use disorder. This is why doctors prescribe it – to allow patients to get access to more affordable pain relievers.

However, there is always a danger of addiction when it comes to prescribed opioid medication. Eventually, a long-term methadone user can experience withdrawal symptoms such as:

  • Slow, shallow breathing, known as respiratory depression
  • Clammy or bluish skin
  • Blue-tinted lips and fingertips
  • Extreme fatigue to the point of being unable to stay awake
  • Stupor
  • Convulsions
  • Vomiting
  • Coma
  • Death

How to Use a MTD Urine Dip Test?

How To Use Rapid Fentanyl Test Strips
  1. Remove the MTD drug test from its sealed pouch and use it as soon as possible. For best results, perform the assay within an hour.
  2. Next, hold the test by the end, where you can see the product name. To avoid contamination, do not touch the test membrane.
  3. Then, holding the test vertically, dip the test in the urine specimen for at least 10-15 seconds. Do not immerse above the maximum line (MAX) on the test. That’s about 1/5th of the way up the test.
  4. After the drug test has finished, remove the test from the specimen and place it on a non-absorbent flat surface. Start the timer and wait for the colored band(s) to appear. Read the result at 5 minutes. Do not interpret it after 10 minutes.

How to Read Methadone Drug Test?

Drug Test Strips Positive Result

Positive

Only one colored band appears, in the control region (C). No apparent colored band appears in the test region (T)

Drug Test Strips Negative Result

Negative

Two colored bands appear on the membrane. One brand appears in the control regions © and another band appears in the test region (T).

Drug Test Strips Invalid Result

Invalid

Control band fails to appear. Results from any test which has not produced a control band at the specified read time must be discarded. Please review the procedure and repeat with a new test. If the problems persist, discontinue using the kit immediately and contact your local distributor.

Why Test for MTD? 

Methadone is a controlled substance and a Schedule II drug. Therefore, it has a high potential for substance abuse which may lead to severe psychological or physical dependence.

Because of the high potential for addiction, those who administer drug screenings may want to incorporate this specific test into their drug testing procedures.

The Urine Dip Tests available from 12 Panel Now may prove to be a more practical solution than a blood test or a hair test.  The urine tests are a fast and accurate way to perform screening.

Many have become addicted after receiving methadone as medication for pain relief. Sadly, abusing or misusing this drug can lead to fatal consequences.

Is Methadone an Agonist?

Yes, it is. It’s a synthetic opioid agonist. As an opioid agonist, it activates the same receptors in the brain as other opioids, but unlike other opioids, it has a longer duration of action and can reduce withdrawal symptoms and cravings.

Does Methadone Show up on a Drug Test?

Yes, it does. It can show up on 10-14 panel drug test cups, dip cards, mouth swabs, or a methadone urine dip test.

What is MTD on a Drug Test?

MTD stands for Methadone, which is a synthetic opioid used commonly in the treatment of opioid addiction, particularly heroin. MTD is used in maintenance therapy because it helps to reduce cravings and withdrawal symptoms, allowing the individual to function more normally.

When it comes to drug testing, MTD is not usually detected on a standard opiate drug test because it has a different structure compared to other opiates. As a result, a separate, specific test is often required to detect methadone. This might be denoted on the test panel as "MTD".

Just like with other drugs, the detection window for methadone in a drug test depends on a number of factors, including the type of test used (urine, blood, hair, etc.), as well as individual factors like metabolism, body mass, and hydration status. In general, methadone can be detected in urine for 3-7 days after the last dose.

What Can Cause a False Positive Drug Test for Methadone?

Antihistamines and some sleep aids containing diphenhydramine (like Benadryl) could cause a false positive result for PCP or methadone. Doxylamine (the active ingredient in Unisom) can also trigger a positive drug result for methadone, opiates, and PCP.

Do Employment Drug Tests Test for Methadone?

It depends on their preferences. Some companies do and are allowed to test for as many substances as they choose.

How Long Does Methadone Stay in Your System?

Methadone has a half-life of about 24 to 55 hours, meaning that it takes approximately 24 to 55 hours for half of the dosage to clear the body. Methadone can typically be processed out of the body within two weeks , but traces of the drug can show up for much longer, depending on the type of drug test used. The amount of time it takes for complete systemic clearance can range from 1.83 days to 13.52 days, with an average estimate of 8 to 59 hours for the clearance of 50% of methadone from the system.

An Overview of Methadone Clinic Protocols

Methadone clinics generally operate in the morning, a schedule that is crucial for maintaining structure in patients’ recovery journeys.

These clinics are equipped with a multidisciplinary team, including medical doctors (MDs), therapists, nurses, pharmacists, and a clinic director, who may also be an MD or a social worker. Each professional plays a specific role in developing and executing individualized treatment plans, offering crucial support as patients progress through recovery.

Patients can access methadone clinics through various channels Referrals may come from primary care providers, therapists, emergency room physicians, or court orders. Additionally, individuals often choose to seek treatment on their own initiative.

Faqs

The MTD/300ng Methadone Urine Test Strip is a rapid drug screening device designed to detect methadone in urine samples at a cutoff level of 300 ng/mL. It provides fast and reliable preliminary screening results within minutes.

The 300 ng/mL cutoff level is the minimum concentration of methadone in urine required to trigger a positive result. Samples below this concentration typically produce a negative result.

Simply dip the test strip into a urine sample for 10–15 seconds without exceeding the maximum line, place it on a flat surface, and read the results after 5 minutes. Do not interpret results after 10 minutes.

A positive result occurs when only the control line (C) appears and no test line (T) is visible. This indicates methadone may be present at or above the cutoff level.

An invalid result occurs when the control line (C) does not appear. If this happens, discard the test and repeat the procedure using a new test strip.

The Serenity Methadone Test Strip offers up to 99% accuracy when used according to the manufacturer’s instructions. Positive results should be confirmed with laboratory testing if required.

Methadone can generally be detected in urine for 2 to 14 days after use, depending on dosage, frequency of use, metabolism, hydration levels, and overall health.

Results are available in approximately 5 minutes, making the test ideal for workplace screening, treatment centers, clinics, and home use.

A negative result shows two colored lines: one in the control region (C) and one in the test region (T), indicating methadone was not detected above the cutoff concentration.

Yes. Certain medications, including antihistamines containing diphenhydramine and sleep aids containing doxylamine, may occasionally cause false-positive results. Laboratory confirmation is recommended when accuracy is critical.

Products labeled FORENSIC USE ONLY (FUO) are not intended to be used or represented as FDA-cleared clinical diagnostic devices when they do not possess such clearance.

FUO devices are intended for appropriate forensic drugs-of-abuse testing applications.

Appropriate users and settings may include:

  • Court systems
  • Police departments
  • Law-enforcement agencies
  • Probation departments
  • Parole departments
  • Juvenile detention facilities
  • Prisons
  • Jails
  • Correctional facilities
  • Appropriate governmental agencies
  • Forensic laboratories
  • Laboratories conducting appropriate forensic testing
  • Other establishments performing forensic testing on behalf of qualifying law-enforcement, correctional, judicial or governmental entities

Products designated Forensic Use Only should be used only in accordance with their applicable labeling and intended use.

2. NOT FOR CLINICAL DIAGNOSIS

A product designated Forensic Use Only is not intended to diagnose, treat, prevent, monitor or identify a disease, illness, medical condition or drug dependency.

An FUO designation must not be represented by a purchaser, reseller or distributor as equivalent to FDA clearance for clinical diagnostic use.

3. AT-HOME AND OVER-THE-COUNTER USE

Unless the particular device is specifically cleared, authorized and labeled for home or Over-the-Counter use, a product labeled Forensic Use Only is not intended to be marketed or sold as a consumer At-Home or OTC diagnostic product in the United States or its territories.

Customers, distributors and resellers are responsible for maintaining the intended-use designation when advertising or redistributing these products.

4. EMPLOYMENT & INSURANCE PRODUCTS

Certain drugs-of-abuse testing devices may be specifically labeled for Employment & Insurance testing.

Where permitted by the specific product’s labeling and regulatory status, Employment & Insurance applications may include certain:

  • Pre-employment testing
  • Workplace testing
  • Random workplace testing
  • Reasonable-suspicion or reasonable-cause testing
  • Post-accident testing
  • Return-to-duty workplace testing
  • Insurance-related screening

An Employment & Insurance designation does not automatically apply to every FUO product or every drug-testing product sold by 12 Panel Now.

The specific labeling and intended use of the individual product controls.

5. FEDERAL DRUG-TESTING PROGRAMS

Employment & Insurance products must not automatically be assumed to satisfy the requirements of federally regulated drug-testing programs.

Unless the particular product and testing methodology are authorized for the applicable program, customers must not assume that a general Employment & Insurance drug test is appropriate for federally regulated programs including those involving:

  • S. Department of Transportation (DOT)
  • Substance Abuse and Mental Health Services Administration (SAMHSA)
  • S. Military
  • Other federal drug-testing programs having specific regulatory requirements

Customers performing federally regulated testing are responsible for ensuring that the specimen type, collection process, chain-of-custody procedures, laboratory testing, confirmatory testing, Medical Review Officer requirements, reporting and other elements of the testing program comply with applicable federal requirements.

6. SPECIALTY AND EMERGING DRUG TESTS

12 Panel Now carries standard and specialty drug-testing configurations.

Depending upon the particular product, labeling, configuration and regulatory status, products testing for certain specialty or emerging analytes may be designated Forensic Use Only or possess another restricted intended use.

Examples may include products screening for:

  • Fentanyl (FEN)
  • Xylazine (XYL)
  • Tianeptine / ZaZa (TIA)
  • Kratom (KRA)
  • Synthetic Marijuana / K2 / Spice
  • Ethyl Glucuronide / EtG
  • Alcohol (ALC)
  • Cotinine (COT)
  • Ketamine (KET)
  • Lysergic Acid Diethylamide (LSD)
  • Methaqualone (MQL)
  • MDPV / certain synthetic cathinones sometimes referred to as Bath Salts
  • Psilocybin / mushroom-related screening configurations
  • Other emerging or non-standard drug analytes

The appearance of an analyte on this list does not mean that every test containing that analyte is automatically classified as Forensic Use Only.

Different products testing for the same substance may possess different regulatory classifications.

Always follow the regulatory designation and intended-use labeling of the specific product.

7. FENTANYL PRODUCTS

Fentanyl testing products are available in different formats and may possess different intended uses and regulatory classifications.

Customers should therefore not assume that all fentanyl test strips, cups, dip cards, cartridges or other fentanyl-testing devices have the same regulatory status simply because they detect fentanyl.

The designation applicable to the particular product controls.

8. ORAL FLUID AND SALIVA TESTING

Certain oral-fluid or saliva drug-testing devices and configurations may be designated Forensic Use Only or have other intended-use restrictions.

The regulatory status of a urine-testing device must not be assumed to apply to an oral-fluid device, or vice versa, merely because both devices test for similar substances.

Customers should verify the designation applicable to the specific oral-fluid product.

9. RAPID TESTS PROVIDE SCREENING RESULTS

Unless the applicable product labeling expressly provides otherwise, rapid drugs-of-abuse tests are screening devices.

A preliminary positive, presumptive positive or non-negative screening result should not automatically be regarded as a definitive laboratory-confirmed result.

Where confirmation is required by law, regulation, employer policy, court procedure, correctional policy, insurance program or other applicable standard, confirmatory laboratory testing should be performed using an appropriate confirmatory methodology.

10. COLLECTION AND CHAIN OF CUSTODY

Organizations using drug-testing devices are responsible for implementing collection and handling procedures appropriate for their program.

Depending upon the application, this may include:

  • Donor identification
  • Specimen integrity procedures
  • Chain-of-custody documentation
  • Secure specimen handling
  • Result documentation
  • Laboratory confirmation
  • Medical Review Officer review
  • Record retention
  • Confidentiality
  • Reporting procedures

12 Panel Now supplies testing products but does not control the customer’s testing program or individual testing procedures.

11. PRODUCT INSTRUCTIONS CONTROL

Customers must follow all applicable manufacturer instructions, package inserts, cutoff information, warnings, limitations and interpretation requirements.

Website descriptions and general educational information do not replace the official labeling and instructions applicable to the individual device.

12. NO MEDICAL DIAGNOSIS

Rapid screening products should not be used as substitutes for medical diagnosis, clinical evaluation or appropriate laboratory confirmation where such services are necessary.

12 Panel Now does not diagnose medical conditions, substance-use disorders or drug dependency through the sale of a testing device.

13. CUSTOMER RESPONSIBILITY

  • The intended application
  • The intended testing program
  • The intended end user
  • The applicable jurisdiction
  • The type of specimen being tested

Why Does My Tracking Info Still Say "Label Created, Not yet in the System" When I Placed It X Days Ago?

If your order was placed via USPS, sometimes your label might not show up in their system even 1-3 days after they have received the package. The same can happen for UPS orders, although they almost always show up in their system the night which they are shipped. If you have any questions regarding the status of your order, please contact us and we will investigate the matter.

If I Pay for a next Day Air Delivery, Am I Guaranteed to Receive It the next Day?

Air deliveries performed by UPS are counted via business days, so you will receive your package the business day after it has been shipped. We also do not ship orders placed after 4 pm EST on the same day, so Next Day orders placed after 4 pm will be shipped the following business day.

Why Can't I Check the Tracking of My Package?

After you place your order, an email will be sent to you with the tracking number within a business day. If you did not receive this email, it's possible that the e-mail was entered incorrectly, sent to your spam folder, or blocked. If you did not receive this email, please call or email us and we'll be happy to give you the status of your shipment.

I Placed My Order but I No Longer Need It. Can I Return It and Get a Refund?

We accept returns for unused items as long as they are placed within 30 days after the day they are purchased. Although shipping is free upon order, we still incur a cost for every order that is shipped, and you will be refunded the amount of your order once we receive the returned goods, minus the cost of shipping.
