Hair analysis is recognized as an effective means for detecting drug and alcohol consumption. Hair captures long-term drug and alcohol histories by embedding biomarkers within the strands of growing hair. When gathered near the scalp, hair can indicate drug and alcohol usage for up to an approximate 3-month period. Hair is easy to collect, relatively hard to tamper with, and simple to transport.
A 1.5-inch segment of roughly 200 hair strands (about the thickness of a #2 pencil) taken closest to the scalp provides 100mg of hair, which is the ideal quantity for both screening and confirmation. For EtG, additional tests, and/or screenings exceeding 10 panels, 150mg of the sample is advised. It is advisable to use a jeweler’s scale to weigh the specimen accurately. If scalp hair cannot be collected, a comparable amount of body hair can be used instead. When mentioning head hair, we mean only scalp hair. All other hair types (facial, axillary, etc.) are considered body hair.
Process Overview
The key steps of laboratory processing for drug testing results include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves introducing a sample into the laboratory’s system initially. This step comprises verifying the sample was properly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any extra data entry not covered by an electronic chain of custody system.
Screening is a preliminary check for potential drug abuse. Screening is a cost-efficient method to eliminate drug use in most samples; however, a positive result requires confirmation to be valid in legal proceedings. Samples that show a presumptive positive during Screening must undergo additional confirmation.
If a sample shows a presumptive positive at the Screening phase, more hair is extracted from the original specimen to prepare for Extraction. During this stage, drugs are extracted from hair at much lower concentrations than in other methods (e.g., urine or oral fluid), which explains why hair drug screening is the most challenging technique to execute.
Confirmation of any positive screen outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed prior to confirmation if required. The complete laboratory process from Accessioning through Confirmation is examined 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 examines the hair strand rather than the follicle below the skin.
