Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and drug use by embedding biomarkers into the strands as they grow. When gathered close to the scalp, hair samples can offer a detection period of around 3 months for both alcohol and drugs. Collecting hair is straightforward, hard to tamper with, and convenient to transport.
A suitable sample is a 1.5-inch segment of approximately 200 hair strands near the scalp, equating to 100mg, which is optimal for both screening and confirmation. For EtG, additional panels, or tests beyond 10 panels, 150mg of the sample is advisable. It's suggested to weigh the specimen using a jeweler’s scale. In the absence of scalp hair, an equivalent amount of body hair can be used. By head hair, we specifically mean scalp hair. Body hair denotes all other hair types (facial, axillary, etc.).
Process Overview
There are four key stages in the laboratory analysis of a drug test result: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial processing of a sample into the lab's system. This phase ensures the sample is properly sealed and shipped, assigns a unique LAN (Laboratory Accessioning Number), and completes any extra data entry absent from an electronic chain of custody.
Screening consists of a preliminary quick test for drug abuse. While Screening offers a cost-effective method to exclude drug use in most samples, a positive result requires a confirmatory test for legal acceptability. Any samples that appear positive during Screening demand further confirmation.
If a sample tests preliminary positive during the Screening phase, additional hair is extracted from the initial sample and prepared for Extraction. At this stage, drugs are extracted at minute concentrations compared to other methods (e.g., urine or oral fluid), making hair drug testing the most challenging to conduct.
Confirmation of any positive result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples undergo washing as required. The entire lab process, from Accessioning to Confirmation, is thoroughly reviewed under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.
