Can hair follicle drug testing show false positives?
A doctor has provided 1 answer
High unlikely: Drug tests of hair has been found to be much more sensitive than urine testing, and is 4-6 times more likely to identify drug users. Although, false positive tests can occur with any test, it is highly unlikely in drug testing with hair, the specificity is 93% - 100%.
