Hair analysis has emerged as a robust method for identifying drug and alcohol usage. Hair offers an extended record of alcohol and drug intake by encapsulating biomarkers within the fiber structure of the hair as it grows. When collected near the scalp, hair samples can reveal a detection period of up to three months for alcohol and drugs. Hair collection is straightforward, relatively hard to tamper with, and convenient to transport.
A 1.5-inch section of roughly 200 hair strands (comparable to a #2 pencil’s diameter) closest to the scalp yields 100mg, the ideal amount for testing and confirmation. For EtG, extended panels, and/or tests beyond 10 panels, a 150mg sample is advisable. It's suggested to weigh the sample using a jeweler's scale. In the absence of scalp hair, a similar quantity of body hair can be used. When discussing head hair, it is exclusively the scalp hair. Body hair encompasses all other hair types (facial, underarm, etc.).
Process Overview
The four primary phases in processing a drug test in the lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary phase where a sample is processed into a lab's system. This includes confirming the sample was sealed and transported correctly, assigning a unique LAN (Laboratory Accessioning Number), and completing any data entry not covered by an electronic chain of custody.
Screening provides a preliminary examination for substances of abuse. While Screening is a cost-efficient method for ruling out drug use in most samples, a positive result necessitates confirmation for legal admissibility. Samples deemed presumptively positive in Screening require secondary verification.
If a sample tests presumptively positive during Screening, additional hair from the initial sample is selected for Extraction. At this stage, substances are extracted from the hair at substantially lower levels compared to other methods (e.g., urine or oral fluid), making hair drug analysis one of the most sophisticated methods available.
Confirmation for any positive screening results is done via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples undergo washing before confirmation as required. The complete lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair standards and the accreditation of ISO / IEC 17025 norms.
