Customer Question

I did a hair folicle tes per my ex wifes demand. The test came ack positive for amphetimines and methamphetimines. I donot do illegal dugs. Ithas to be a false positive fom edications i take from docotor. however in the past few months have passed random urine screen at Guardian at Lietms office and had a 850.00 psych eval done that essentially indicated I am not a drug user. Guardian at lietm filed a motion to review hair foliclle test results. Guadian at lietm indicated that she did not feel my kids were in danger or harms way whn with me and commented on how beautiful my home was. Im worried the juge is going to think im a drug user or will he see it can b a reflection of my medications. here is a list of my medications that i hav the bottles to pove from docto:
Benzonate 100mg 3times daily as needed for cough.

Welcome to Just Answer and thanks for your question. Hair follicle tests are run via GC/MS (gas chromatography/mass spectrophotometry where every chemical is different, and differentiating between them is even more accurate than fingerprint analysis. Unless the samples were somehow switched in the chain of custody with another person's sample, then if amphetamines and methamphetamine were found, then those were the drugs that had been used at some time in the past 3 months. There are no false positives with GC/MS analysis.

Perhaps you didn't understand. GC/MS testing can tell exactly what drugs, medications, etc. have been taken. There are no "false positives." Those only occur with dipstick style urine screening tests. GC/MS testing removes all doubt. If you had absolutely not used any amphetamine or methamphetamine for the 3 months prior to the tests, then the only explanation was that the samples were switched with another person's. False positive is not a possibility.
