Trazadone is RARELY included in drug testing panels. However, it has been reported as a cause for false positive screening (immunoassay) tests for amphetamines. GC/MS confirmation at a laboratory will however determine that the test is in fact a false positive.

What is GC/MS confirmation? It will confirm false positive?
Expert:  Family Physician replied 5 years ago.
GC/MS is gas chromatography-mass spectrometry an advanced forensic testing methodology that essentially gives a "chemical fingerprint" of the specimen. It will determine if the test is a true ("real") positive or a false positive.

I have no script for the Trazodone, but take it to help me sleep. If I get back positive for amphetimines, how can I explain it without having to admit I am taking a drug with no script?
Expert:  Family Physician replied 5 years ago.
If you get a positive for amphetamine, you would need to request that the specimen would be confirmed with GC/MS.

The GC/MS confirmation will NOT show amphetamine, therefore it would be reported as NEGATIVE.
