Hair testing is now regarded as an effective means for detecting drug and alcohol usage. Through capturing biomarkers within the fibrous structure of growing hair, it yields an extended history of alcohol and drug consumption. When taken from near the scalp, hair samples offer close to a 3-month window for detecting alcohol and drugs. Hair is straightforward to collect, challenging to tamper with, and easy to transport.
A 1.5-inch sample of about 200 hair strands (approximately the diameter of a #2 pencil) nearest to the scalp will yield 100mg, the optimal sample for screening and verifications. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is advised. Using a jeweler’s scale to weigh the specimen is recommended. If scalp hair is unobtainable, an equivalent body hair sample may be used. When mentioning head hair, it refers solely to scalp hair. Body hair includes all other hair types (facial, axillary, etc.).
Process Overview
There are four inherent steps in laboratory processing of a drug test: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial procedure of incorporating a sample into the laboratory system. It involves confirming the sample was sealed and delivered correctly, generating a random LAN (Laboratory Accessioning Number), and performing additional data logging not provided by an electronic custody system.
Screening constitutes a preliminary swift assessment for substances of abuse. While Screening efficiently rules out drug use in most cases, a positive outcome demands confirmation for court viability. Samples with presumptive positives in Screening require secondary verification.
Upon encountering a presumptive positive in Screening, further hair from the original sample is prepared for Extraction. Drugs are isolated at notably lower concentrations in hair than in other sample types (e.g., urine or oral fluid), making hair drug testing exceptionally challenging.
Positive screenings undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo necessary washing before confirmation. The entire process from Accessioning to Confirmation is audited under both CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation.
