Frequently Asked Questions about Rapid Point of Care Diagnostics

Have a question about rapid point of care diagnostics or other drug testing topics? Take a look at our FAQ for more information.

  • How accurate are the diagnostic results?

    Most tests are U.S. FDA cleared to be 99.9% accurate, as well as CLIA waived and approved for home use, certifying that they are sufficiently simple to operate and interpret. Any test we make that may be considered a niche test, for which the FDA has not yet established guidelines, is held to this same standard and will be cleared after protocols are established by the FDA.

  • How fast can the results be read?

    Negative results may be seen in as little as one minute. Positive results may be read after 5 minutes. Results should not be read after 60 minutes.

  • Are specific drugs more common than others to provide inaccurate results, based on multiple drugs interacting?

    Some tests do not distinguish between therapeutic use of a drug and abuse of the same drug. A test may yield preliminary positive results when prescription tricyclic antidepressants, barbiturates, benzodiazepines, methadone, buprenorphine or opiates are ingested, even at therapeutic doses. There are no uniformly recognized drug levels for these prescription drugs in urine.

  • How should the tests be stored and for how long?

    Room temperature storage, or 2-30 degrees Celsius / 35.6-86 degrees Fahrenheit is recommended. Do not freeze the test. The expiration date is written on the pouch that contains the device, most tests have a shelf life of 2 years from the date of manufacture.

  • The test line is very faint. Is this a positive or negative result?

    A red or pink line next to the “T1” or “T2” (drug test line) under the drug name indicates a negative result for that drug, even if the line is very faint. In the case of a positive result, there will be NO line at all. ANY line, no matter how faint, indicates a negative result.
