This test alone is not always accurate or reliable. If the initial screen is positive, a second test should be done. For a test result to be reported as positive, both test results must agree. If your drug test is positive, the MRO reviews the results, makes sure the chain of custody procedures were followed, and contacts you to make sure there are no medical or other reasons for the result. It is only at this point that the MRO may report the positive test result to the employer.
Medications can sometimes cause a positive test result.
If this is the case, and if a doctor prescribed the medicine, the test is reported as negative. The DHHS requires that these and other guidelines be met for a drug testing laboratory to be certified. If you are interested in learning more about the testing procedures that your organization is using, refer to the official policy or ask your supervisor, manager, or union steward for information. When reporting to the test site, you may be asked for a picture identification. You should sign the label on the container.
