Addiction and Substance Abuse

Steroids & asthma medication



My son takes Albuterol and Azmacort; he test positive for an anabolic steroid, Trenbolone. It was a urine test. Can this be a false positive due to his asthma medication?


Thank you for your question.

NetWellness receives numerous questions about drug screens and possible false positive results. NetWellness experts do not provide information on ways to avoid the detection of drugs in the body nor can they address specific questions related to individual drug screens.

It is recommended that any and all positive screenings be followed up by a second, more selective test to confirm the result and rule out any false positives. Positive test results on urine drug screens must be verified with a confirmatory test before they can be used for legal purposes. Follow up tests used to confirm a positive screening test should be performed using a methodology different from that which performed the initial screening test. The current standard confirmatory test is gas chromatography/mass spectrometry (GC/MS).
