Hair analysis is regarded as a robust method for identifying substance use. Hair offers an extended timeline of alcohol and drug consumption by capturing biomarkers within the strands. Collected near the scalp, hair can reveal usage within roughly a 90-day period. Collection is straightforward, less prone to tampering, and convenient shipping.
A sample measuring 1.5 inches of approximately 200 hair strands (about the width of a #2 pencil) close to the scalp provides 100mg, optimal for testing. For EtG, additional tests, or panels exceeding ten, 150mg is suggested. It's advisable to measure the sample using a jeweler’s scale. If scalp hair isn't available, equivalent body hair can be obtained. "Head hair" refers to scalp hair, while "body hair" encompasses all other hair forms (facial, axillary, etc.).
Process Overview
The process for lab analysis of drug tests consists of four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves entering a sample into a lab's database. This step includes checking that the sample is intact and shipped correctly, assigning an LAN (Laboratory Accessioning Number), and completing any needed data entry not captured by an electronic chain of custody.
Screening performs an initial examination for drugs. Although it's a cost-effective method to exclude drug use for most samples, a positive result requires confirmation to be legally defensible. Any samples flagged as positive during Screening need further confirmation.
If a sample tests positive at the Screening step, additional hair is extracted from the initial sample and readied for Extraction. During this phase, drugs are isolated from hair at concentrations much lower compared to other methods (e.g., urine or oral fluid), making hair drug screening a complex procedure.
Positive screenings are confirmed via GC/MS, GC/MS/MS, or LC/MS/MS. All preliminary positive samples are cleansed before confirmation if necessary. The lab process from Accessioning to Confirmation is reviewed under CAP (College of American Pathologists) Hair guidelines and accredited to ISO / IEC 17025 standards.

Note: Although termed "hair follicle tests" often, the procedure examines the hair strand rather than the follicle beneath the scalp.
