Hair analysis is gaining recognition as a robust method for detecting drug and alcohol usage. Hair retains a longitudinal record of alcohol and other substances by capturing biomarkers within its fibers as it grows. When sourced near the scalp, hair can reveal up to a roughly 3-month detection timeframe for alcohol and other substances. Hair is straightforward to collect, challenging to adulterate, and straightforward to transport.
A 1.5-inch hair sample of about 200 strands (approximating the thickness of a #2 pencil) from nearest to the scalp provides 100mg of hair, which is the optimal sample for screening and verification. For EtG, add-ons, and/or tests exceeding 10 panels, a 150mg specimen is advisable. It's suggested to weigh the specimen using a jeweler’s scale. If scalp hair is not available, a comparable quantity of body hair may be collected. "Head hair" specifically denotes scalp hair only. "Body hair" encompasses all other hair types (incl. facial, axillary, etc.).
Process Overview
The process comprises four principal stages in the laboratory analysis of a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses processing a sample into a lab's system. This entails confirming the sample was sealed and transported correctly, assigning an arbitrary LAN (Laboratory Accessioning Number), and filling out any supplementary data entry absent from an electronic chain of custody system.
Screening entails an initial swift assessment for substances of abuse. Although Screening is a budget-friendly method to exclude drug use in most samples, a positive screen must be verified for judicial validity. Any samples that suggest positivity in Screening necessitate a secondary confirmation.
Should a sample seem positive during the Screening stage, additional hair is extracted from the original specimen and prepared for Extraction. Here, drugs are isolated from hair at a considerably lower concentration than in alternative methodologies (like urine or oral fluid), which contributes to the complexity of hair drug screening.
Confirmation of any positive screening outcome is performed with GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positivity undergo washing prior to confirmation as required. The comprehensive laboratory procedure from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
