Hair examinations are now regarded as a potent instrument for identifying alcohol and drug consumption. Hair strands capture biomarkers within their fibers, recording a prolonged history of substances like alcohol and drugs. When gathered near the head, hair can offer a detection period of up to roughly three months for alcohol and other substances. The procedure of collecting hair is easy, somewhat resistant to tampering, and convenient for transportation.
A 1.5-inch length comprising roughly 200 hair strands (similar in size to a #2 pencil) nearest to the head will yield 100mg of hair, which is the perfect sample size for both initial and confirming tests. For EtG tests, add-ons, or assessments beyond 10 panels, 150mg of the sample is advised. It's recommended to measure the sample weight with a jeweler’s scale. In the absence of scalp hair, a comparable amount of body hair may be used. The term head hair specifically denotes scalp hair. In contrast, body hair encompasses all other hair variants (facial, axillary, etc.).
Process Overview
The key stages in laboratory processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the initial sample processing within a lab system. This process ensures the sample was meticulously sealed and transported, assigns it a random LAN (Laboratory Accessioning Number), and completes any data logging absent from an electronic chain of custody system.
Screening serves as an initial assessment to detect substance misuse. Although Screening provides a cost-effective approach to eliminate drug use in most cases, any positive screen requires confirmation to be valid in legal contexts. Presumptive positive samples in the Screening phase necessitate follow-up confirmation.
For samples indicating potential positives in the Screening phase, additional hair is extracted from the original sample for Extraction. Drugs in this stage are extracted from hair at much lesser concentrations than via other methods (e.g., urine or saliva), making hair drug testing the most challenging procedure to perform.
Confirmation of any positive findings during screening employs GC/MS, GC/MS/MS, or LC/MS/MS techniques. Positive samples undergo necessary washing prior to the confirmation stage. The entire process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair classification and complies with ISO / IEC 17025 standards.
