Hair testing is now recognized as a formidable method for detecting drug and alcohol consumption. Hair captures a prolonged track record of alcohol and drug usage by encasing biomarkers within its growing strands. When collected near the scalp, hair offers up to a 3-month detection timeframe for alcohol and drugs. It's easy to collect, relatively tough to alter, and convenient to ship.
A 1.5-inch slice comprising roughly 200 hair strands (about the size of a #2 pencil) nearest the scalp yields 100mg of hair, which is the optimal sample for analysis. For EtG, additional tests, or tests beyond 10 panels, 150mg of the sample is necessary. It's advised to weigh the sample using a jeweler’s scale. If scalp hair isn't accessible, the equivalent quantity of body hair can be collected. "Head hair" refers strictly to scalp hair, while "body hair" encompasses all other hair forms (facial, axillary, etc.).
Process Overview
There are four primary steps in the lab processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the step where a sample is initially processed into a lab's system. This includes confirming that the sample was sealed and transported correctly, allocating a unique LAN (Laboratory Accessioning Number), and completing any extra data input not covered by an electronic chain of custody system.
Screening serves as an initial swift examination for drugs of abuse. While Screening is an economical approach to dismiss drug usage in most samples, a positive screen must be validated to stand up in court. Samples that are presumptively positive in Screening require further confirmation.
If a sample shows presumptive positivity during Screening, extra hair is taken from the initial sample and readied for Extraction. During this phase, drugs are drawn from hair at lower concentrations compared to other methodologies (such as urine or oral fluid), which explains why hair drug testing is one of the most complex methodologies to execute.
Confirmation of any positive screen is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as needed. The complete lab process from Accessioning to Confirmation is evaluated under both CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
