Hair analysis has emerged as a significant method in identifying substance use, including drugs and alcohol. By trapping biomarkers within the hair fibers, hair offers a comprehensive history of substance ingestion. When cut near the scalp, the hair can reveal up to roughly a 3-month timeframe for substance detection. It is easy to collect, hard to tamper with, and simple to transport.
Collecting a 1.5-inch segment of about 200 hair strands closest to the scalp provides 100mg, which is optimal for both screening and validation. For tests involving EtG, additional panels, or those exceeding 10 panels, a sample of 150mg is advised. Using a jeweler’s scale to weigh the sample is recommended. If scalp hair is not accessible, a similar quantity of body hair can be used. The term head hair exclusively denotes scalp hair, while body hair includes all alternative hair types such as facial and axillary hair.
Process Overview
Four essential steps constitute the laboratory processing of a drug test: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial handling of the sample within a lab's workflow. This step ensures the sample is appropriately sealed for shipping, assigns a random LAN (Laboratory Accessioning Number), and incorporates any further data input not managed by an electronic chain-of-custody system.
Screening acts as a preliminary rapid test for substance abuse. Although it's a cost-effective measure to eliminate drug use in most specimens, any positive screen demands further confirmation to be legally valid. Presumptive positive results from the Screening require subsequent validation.
If a specimen turns up presumptively positive in Screening, additional hair is taken from the original sample for Extraction. This phase involves extracting substances from hair at lower concentrations compared to other methods such as urine or saliva tests, which is why hair testing is considered the most challenging technique.
Verification of positive screening outcomes is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples, if necessary, undergo washing before confirmation. The entire laboratory procedure from Accessioning to Confirmation is subjected to oversight by both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standard accreditation.

Note: Although often labeled as "hair follicle tests," this method examines the hair strand, not the follicle beneath the scalp.
