Hair analysis has emerged as a highly effective method for identifying drug and alcohol consumption. Hair captures extended-term evidence of alcohol and other substances by embedding biomarkers in its fibers as it grows. When collected near the scalp, hair samples can detect drugs and alcohol for up to roughly three months. Hair is straightforward to collect, challenging to alter, and convenient to transport.
A hair sample measuring 1.5 inches with approximately 200 strands (about the size of a #2 pencil) taken closest to the scalp yields 100mg of hair, the optimal sample size for both screening and confirmation. For EtG, additional tests, and/or over 10-panel tests, 150mg of the specimen is advised. We suggest using a jeweler’s scale for weighing the specimen. Should scalp hair be unavailable, an equivalent quantity of body hair can be collected. When we mention head hair, we refer exclusively to scalp hair. Body hair comprises all other types of hair (such as facial, axillary, etc.).
Process Overview
There are four primary stages in the laboratory analysis of a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial handling of a sample within a laboratory’s system. This process involves confirming the sample was correctly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any additional information entry not handled through an electronic chain of custody system.
Screening involves a preliminary rapid check for drugs of abuse. While Screening offers a cost-effective means of eliminating drug use in most samples, a positive screen must be validated for legal admissibility. Samples that show presumptively positive results in Screening require a secondary validation.
If a sample displays presumptive positivity during the Screening phase, further hair is extracted from the initial specimen for Extraction. This step involves extracting drugs from hair at much lower concentrations than found in other methodologies (e.g., urine or oral fluid), highlighting why hair drug screening is the most intricate methodology.
Any positive screening result is verified through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation when necessary. The entire laboratory procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
