Hair testing has emerged as a significant instrument for identifying drug and alcohol consumption. Hair serves as a long-term repository for alcohol and drugs by encapsulating biomarkers within the fibers of the developing hair strand. When sourced from near the scalp, hair can reveal up to a 3-month detection window for alcohol and drugs. Its collection is straightforward, challenging to tamper with, and simple to transport.
A 1.5-inch segment consisting of roughly 200 hair strands (akin to the size of a #2 pencil) closest to the scalp will produce 100mg of hair, forming the ideal sample for testing and verification. For EtG, additional analyses, and/or more than 10-panel tests, 150mg of the sample is advised. Measuring the sample on a jeweler’s scale is recommended. If scalp hair is not available, a comparable quantity of body hair may be used. When discussing head hair, it pertains solely to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The four key stages in the lab processing of a drug screening result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the primary intake of a sample into a lab’s framework. This involves confirming that the sample was securely sealed and dispatched accurately, designating a random LAN (Laboratory Accessioning Number), and finalizing any data entry not catered to by an electronic custody chain system.
Screening entails an initial rapid assessment for substance abuse. Although Screening is an affordable method to negate drug usage in most samples, a positive screen must be verified for court acceptability. Any samples that test presumptively positive in Screening necessitate secondary confirmation.
If a sample tests presumptively positive during the Screening phase, additional hair is collected from the initial sample and readied for Extraction. In this phase, drugs are extracted from hair at a substantially lower concentration level compared to other methods (ex. urine or oral fluid), rendering hair drug testing the most complex method to execute.
Confirmation of any positive screening outcome is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The entire lab process from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Note: Often termed "hair follicle tests", the analysis targets the hair strand and not the follicle beneath the scalp.
