• Hair Follicle Laboratory GC/MS Drug Test 10 tests

Testing of hair will provide an indicator of drug use at the time the hair was grown. Hair samples have several advantages over urine samples, particularly length of surveillance period (months rather than days) and resistance to tampering. The time period covered is limited up to 90 days according to the length of the hair sample (Each 30 days required 1/2” hair specimen).
