Hair examination is now regarded as an effective approach for identifying the usage of drugs and alcohol. Hair captures a long-term record of alcohol and other substances by embedding biomarkers within the expanding hair fibers. When collected near the scalp, hair offers a detection window extending up to about 3 months for alcohol and other substances. The collection of hair is straightforward, comparatively hard to tamper with, and conveniently shippable.
A 1.5-inch segment consisting of around 200 hair strands (approximately the dimension of a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal amount for screening and confirmation. For EtG, supplementary tests, and/or tests exceeding 10 panels, 150mg of the sample is advisable. It is suggested to weigh the sample using a jeweler’s scale. If scalp hair is not present, an analogous quantity of body hair might be gathered. When referring to head hair, this exclusively pertains to scalp hair. Body hair is inclusive of all other hair varieties (like facial, axillary, etc.).
Process Overview
The complete laboratory processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial handling of a sample into a lab’s system. This step incorporates confirming that the sample is properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any further data input absent in an electronic chain of custody system.
Screening comprises an initial rapid evaluation for substances of abuse. Although Screening is an economical solution to exclude drug use in most samples, a positive screen necessitates confirmation to be usable in legal proceedings. Samples yielding presumptive positive results in Screening require subsequent verification.
If a sample shows presumptive positivity in the Screening phase, additional hair is extracted from the initial sample and prepared for Extraction. During Extraction, drugs are isolated from hair at notably lower concentrations than in other methods (e.g., urine or oral fluid), contributing to the complexity of performing hair drug screening.
Confirmation of any positive screening outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples undergo necessary washing. The entirety of the lab procedure, from Accessioning to Confirmation, is assessed under both the CAP (College of American Pathologists) Hair designation and accreditation per ISO / IEC 17025 standards.
