Hair tests are now recognized as an effective method for detecting drug and alcohol usage. The hair captures long-term evidence of alcohol and drug presence by embedding biomarkers in the hair shaft. When hair is cut close to the scalp, it can reveal usage patterns over approximately a 3-month timeframe. This method of collection is straightforward, resistant to tampering, and easily transportable.
A 1.5-inch sample consisting of roughly 200 hair strands (similar in thickness to a #2 pencil) taken near the scalp provides about 100mg of hair, which is ideal for both initial testing and verification. For EtG, additional analysis, or tests exceeding 10 panels, a sample of 150mg is advised. Using a jeweler’s scale to weigh the sample is recommended. If scalp hair cannot be obtained, a proportional quantity of body hair is acceptable. When mentioning head hair, it refers specifically to scalp hair, while body hair includes all other varieties (such as facial or axillary hair).
Process Overview
The lab process for a drug test result encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the introductory step involving the integration of a sample into the lab’s workflow. This step encompasses confirming the sample's sealing and appropriate shipment, assigning a unique LAN (Laboratory Accessioning Number), and performing any supplementary data input absent from an electronic chain of custody.
Screening entails a preliminary evaluation for the presence of drugs. Although a cost-efficient method to potentially rule out drug consumption in most cases, a positive result from Screening mandates confirmation for legal validity. Samples with an initial positive result in Screening require further verification.
In cases where the Screening stage suggests a positive result, additional hair is extracted from the original sample and set up for Extraction. At this phase, drugs are separated from hair at significantly reduced concentrations compared to other methods (e.g., urine or oral fluid), which makes hair drug testing uniquely challenging.
Verification of any positive result from Screening is conducted using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo washing before confirmation when necessary. The complete lab process from Accessioning to Confirmation adheres to standards set by both the CAP (College of American Pathologists) with its Hair designation and the ISO / IEC 17025 accreditation.

Note: Though often termed "hair follicle tests", the testing analyzes the hair itself, not the hair follicle beneath the skin.
