Frequently Asked Questions about Rapid Drug Testing

  1. Why does the BUP strip take longer and more faint compared to other drug strips?

    Drug Testing Cups and Dip Cards test Buprenorphine (BUP) at 5ng/mL. Testing at such a sensitive level is necessary to effectively detect BUP use, the test chemistry takes a bit longer than other test lines to form and tends to form a lighter line because of the low cut-off level. It is very important to remember that it is completely normal for the BUP line to take longer to form and be less intense (lighter) than the surrounding test strips. Make sure to wait the full 5 minutes before calling a BUP line positive.

  2. Why do some test (T) lines appear more faint than others?

    The presence of a line, regardless of its intensity, is to be read as a NEGATIVE result. Because of the chemical composition of certain drugs and metabolites along with the test strip chemistry, variation in cut-off levels for each drug, and expected variation in human donor specimen, it is normal for some lines to appear more intense (darker) than others. Any shade of color in the test (T) region should be considered a NEGATIVE result.

  3. How accurate are the results of a rapid drug test?

    Very accurate. The results reach up to 99% results in accordance with GC/MS, the reference method of confirmation in the laboratory.

  4. Why would EDDP be advantageous over a test for MTD?

    In many cases, the test administrator would like to know if the individual is actually taking their prescribed methadone and not diverting it. If you are using a standard methadone test you cannot tell the difference as you can sprinkle some MTD from a tablet into the sample and you will get a positive. If you use an EDDP test, you are testing for the MTD metabolite which allows you to make sure the person is taking their recommended dose. Additionally, you will also pick up the abuser that is not prescribed and is just abusing it.

  5. Can over-the-counter medications affect drug test results?

    Yes, certain over-the-counter medications can produce false-positive results for specific drugs. It's advisable to inform the test administrator about any medications or supplements you've taken recently to ensure accurate results.

  6. How long do drugs stay detectable in the system?

    The detection time for drugs varies based on factors such as the type of drug, frequency of use, and individual metabolism. Generally, drugs can be detected in urine for a few days to several weeks after use.

  7. Are there any factors that can cause false-positive results?

    Yes, certain factors such as certain foods, medications, or medical conditions can lead to false-positive results. It's essential to provide a complete medical history to ensure accurate interpretation of results.

  8. What is the difference between urine and saliva drug tests?

    Urine and saliva drug tests have different detection windows and sensitivity levels. Saliva tests are generally more effective for detecting recent drug use, while urine tests may detect substances over a longer period.

  9. Can secondhand smoke result in a positive drug test?

    While it's rare, exposure to secondhand smoke, especially in enclosed spaces, can potentially lead to trace amounts of drugs in the system. However, the levels are usually too low to cause a positive test result.

  10. How do rapid drug tests work?

    Rapid drug tests typically use immunoassay technology to detect specific drugs or their metabolites in urine, saliva, or other biological samples. These tests provide quick results within minutes by indicating the presence or absence of drugs in the system.

  11. What drugs can your rapid tests detect?

    Our rapid drug tests are designed to detect a range of commonly abused substances, including but not limited to marijuana, cocaine, opiates, amphetamines, buprenorphine, MDMA, tricyclic antidepressants, benzodiazepines, PCP, and many more panels. The specific drugs covered depend on the type of test and panel chosen.

  12. How accurate are your rapid drug tests?

    Our rapid drug tests are highly accurate, with results reaching up to 99% accuracy in accordance with reference methods such as GC/MS. These tests are reliable tools for quick and efficient screening.

  13. Why choose rapid drug tests over laboratory tests?

    Rapid drug tests offer the advantage of quick results, typically within a few minutes, allowing for timely decision-making. They are cost-effective, convenient, and can be administered on-site without the need for laboratory processing. For comprehensive confirmation, laboratory tests can be used in conjunction with rapid tests. Should you require laboratory based confirmation services, please call our office for assistance.

  14. How can I ensure the integrity of the results?

    Follow the provided instructions carefully to ensure accurate and reliable results. It's important to check the expiration date of the tests, store them properly, and use them within the specified timeframe. Additionally, ensure that the collection process is done correctly to avoid any potential issues.
