What Causes False Positive Test Result For Ecstasy While On Tegretol?
Question: im a 60 year old women and i take tegretol and had a false positive blood test for exstacy, why
Brief Answer:
False positive drug tests
Detailed Answer:
Thank you for contacting HCM with your health care questions
You recently had a urine drug test that was positive for MDMA or Ecstasy. There are frequent false positive tests for MDMA. Several medications can turn a urine test positive including cold or flu medications that have decongestants in them. Medications like trazodone and possibly even tegretol and other seizure medications.
I would ask the lab to do confirmatory testing so you can prove that you did not use ecstasy. The problem with screening tests that there will be a high number of false positives. That is the nature of screening tests as they are trying to capture all possible positives. This is called high sensitivity but low specificity. In other words high number of positive tests but not very accurate for MDMA. So I would strongly urge that you have a confirmatory test done to clear your name and record
