A member asked:
Is there a specific test which can differentiate between pseudoephedrine and amphetamines which can be requested in the case of a false positive?
A doctor has provided 1 answer
Absolutely: Many drug screens look at classes of chemicals first and then there are specific tests that break that down further. There is always a confirmatory test that helps with false positive drug screens. Talk to your doctor!
