Hair analysis has become recognized as a significant resource for identifying drug and alcohol consumption. Hair retains a prolonged record of alcohol and drugs through embedding biomarkers within the fibers of the growing strand. When extracted near the scalp, it can offer up to a 3-month look-back period for alcohol and other substances. Hair is easy to gather, relatively hard to tamper with, and straightforward to transport.
A 1.5-inch segment of around 200 hair strands (approximately the thickness of a #2 pencil) closest to the scalp will provide 100mg, the preferred sample mass for both screening and verification. For EtG, additional panels, and tests beyond 10 panels, 150mg of the sample is advisable. We suggest measuring the specimen with a jeweler's scale. If scalp hair is lacking, a similar amount of body hair can be used. When mentioning head hair, we refer solely to scalp hair. Body hair encapsulates all other varieties (facial, axillary, etc.).
Process Summary
The laboratory procedure for processing a drug test result consists of four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the early process of entering a sample into a lab’s framework. This involves checking that the sample was correctly sealed and transported, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any extra data entry not available through an electronic chain of custody system.
Screening involves a preliminary rapid examination for substances of abuse. Screening is a budget-friendly method to disregard drug presence in most samples; however, a positive outcome necessitates confirmation to be valid in legal proceedings. Samples tentatively positive at Screening must undergo further verification.
If a sample shows a tentative positive result during the Screening, more hair is extracted from the original specimen to prepare for Extraction. Here, drugs are isolated from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), which is why hair drug testing is the most complex methodology to conduct.
Confirmation of any positive screen result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumption-positive samples undergo washing before confirmation if necessary. The complete laboratory sequence from Accessioning to Confirmation is inspected under both the CAP (College of American Pathologists) Hair criteria and the accreditation to ISO / IEC 17025 standards.
