Identified as a potent method, hair testing serves in detecting substance use. Hair locks in biomarkers within its fibers, offering a prolonged history of drug or alcohol ingestion. When sampling close to the scalp, hair testing can reveal substance use up to roughly three months. The collection process is straightforward, with a minimal chance of tampering, and easy transportation.
Acquiring a 1.5-inch hair segment near the scalp, consisting of about 200 strands (similar in size to a #2 pencil), yields 100mg, suitable for examination and confirmation. For expanded tests or EtG evaluations, 150mg is advisable. Using a jeweler’s scale is recommended for measuring the sample. If scalp hair isn’t present, equivalent body hair is an option. "Head hair" specifically indicates scalp hair, while "body hair" encompasses other types such as facial or axillary hair.
Process Overview
The procedure for processing drug tests in labs includes four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is about starting the sample’s lab integration, which entails ensuring it’s sealed and dispatched correctly, allocating a LAN (Laboratory Accessioning Number), and organizing any supplementary data entry that isn’t managed by an e-chain custody system.
Screening offers an initial rapid assessment for substance abuse. While it's a cost-effective means to dismiss drug use in most samples, a positive detection necessitates validation for legal acceptability. Presumptive positives in Screening require follow-up confirmation.
On detecting positivity in Screening, extra hair from the initial batch is prepared for Extraction. This phase extracts substances from hair at much lower levels than other methods (like urine or oral fluid), highlighting the complexity of hair testing.
Any positive outcomes in Screening undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. Prior to Confirmation, positive samples are washed as needed. The complete lab sequence, from Accessioning to Confirmation, adheres to CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 standards.

Limitations:
Note: Known as "hair follicle tests", these evaluations analyze the hair strand rather than the scalp's hair follicle.
