Hello, this is Dr. David. I am reviewing your question now and will be with you momentarily.

Expert:  Dr. David replied 5 months ago.

false negative or false positive for what substance?

do you have the result of your hair follicle testing?

Customer: replied 5 months ago.
10000 ng/ml for methamphetamine not sure how many ng/ml for amphetamines.
Expert:  Dr. David replied 5 months ago.

so your urine test was positive for methamphetamines?

Ephedrine. Xenadrine RFA-1 contains 25 mg of Ephedra alkaloids in the form of ma huang

which can cause false positive for amphetamines or methamphetamines on urine screening tests.

but confirmatory MS/CG tests should be negative if you don't use amphetamines.

How long do they keep sample for MS/CG testing
Expert:  Dr. David replied 5 months ago.

they should do confirmatory tests with any hair screening tests.

yes, using ephedrine can cause false positive for emphetamines.
