Hair analysis is increasingly recognized as a robust method for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and drugs by embedding biomarkers within the hair strand's fibers during growth. When collected near the scalp, hair can reveal a timeline of up to around three months for alcohol and drugs detection. Hair is easy to gather, hard to tamper with, and convenient to transport.
A 1.5-inch section with roughly 200 hair strands (comparable to a #2 pencil) closest to the scalp yields 100mg of hair, the optimal sample for both screening and confirmation. For EtG, add-ons, and/or screens beyond 10 panels, a 150mg sample is suggested. The specimen should ideally be weighed on a jeweler’s scale. If scalp hair is not an option, an equivalent quantity of body hair could be used. When discussing head hair, we specifically mean scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).
Process Overview
The key stages in the laboratory’s handling of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves entering a sample into the lab's system. This process verifies the sample was securely sealed and properly shipped, assigns a LAN (Laboratory Accessioning Number) at random, and completes any missing data entry unsupplied by an electronic chain of custody system.
Screening is a preliminary assessment for substances of abuse. Although Screening is economically sensible for eliminating drug use in most samples, a positive result must be confirmed to be legally valid. Samples with a presumptive positive in Screening need further confirmation.
When a sample is presumed positive in Screening, additional hair is extracted from the original sample and readied for Extraction. In this phase, drugs are drawn from hair at a significantly lower density than in alternative methods (such as urine or oral fluid), which makes hair drug testing particularly challenging.
Positive screening confirmations are executed through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive specimens undergo washing prior to confirmation when necessary. The complete laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair standard and the ISO / IEC 17025 accreditation.

Note: While commonly termed as "hair follicle tests," the test actually examines the hair strand and not the follicle beneath the scalp.
