Lately, the trend in drug testing increasingly favors hair follicle tests. Employers, courts, and substance abuse experts are opting for hair drug tests over the conventional urine tests. Hair follicle tests are invaluable to employers with strict drug-free policies, judicial systems, and individuals on probation, as they offer a much longer detection period—up to 90 days—making them almost impossible to falsify. Yet, for detecting recent usage within 5 days, urine tests remain the gold standard.

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair offers a chronic record of alcohol and drug use by embedding biomarkers within the strands of hair as they grow. When obtained near the scalp, hair can illustrate up to a three-month period of alcohol and drug use. Hair is not only easy to collect and hard to tamper with, but also straightforward to transport.
A 1.5-inch section containing about 200 hairs (roughly the diameter of a #2 pencil) closest to the scalp will yield 100mg of hair, which is the optimal amount for testing and verification. For EtG, add-ons, and/or tests exceeding 10 panels, a specimen of 150mg is advised. It's suggested to measure the specimen using a jeweler’s scale. If there's no scalp hair available, a comparable quantity of body hair may be collected. "Head hair" specifically relates to scalp hair. "Body hair" includes all other hair types (facial, axillary, etc.).
Process Overview
The four essential phases in lab processing for drug testing results include Accessioning, Screening, Extraction, and Confirmation.
Accessioning incorporates the first handling of a sample in the lab’s system. This involves confirming the sample was properly sealed and shipped, assigning an arbitrary LAN (Laboratory Accessioning Number), and fulfilling any additional data-entry tasks not covered by an electronic chain of custody.
Screening conducts an initial brief assessment for substance misuse. Despite Screening being a cost-efficient approach to exclude drug use in the majority of cases, a positive result must be confirmed for legal acceptance. Samples with a presumptive positive in Screening require another confirmation.
If a sample tests presumptively positive during Screening, extra hair is extracted from the primary sample and prepped for Extraction. In this procedure, drugs are drawn out from hair at lower concentrations compared to other methods (like urine or oral fluid), making hair drug testing the most intricate method to execute.
Confirmation of a positive Screening is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are washed before confirmation as needed. The complete lab workflow from Accessioning to Confirmation is scrutinized per the CAP (College of American Pathologists) Hair designation and accreditation per ISO / IEC 17025 standards.
