I know someone that tested positive on a hair follicle test

Customer Question

hi I know someone that tested positive on a hair follicle test for cocaine but swears she is clean for 90+ days she is 28% over what the allowed rate is and has tested positive for the metabolite. I want to believe her but I can't find anything to dispute what I know from the report. any suggestions?
JA: Is this a time sensitive issue? What type of specimen are they testing?
Customer: hair follicle
JA: Anything else in your medical history you think the doctor should know?

the cut off for hair testing is 90 days.

Often the detection time is less.

there is no real chance based on the test that she was over 90 days.

Lab error or getting the wrong sample, or a contaminated sample might explain it.
