Hair testing is now recognized as a potent method for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and drug exposure by embedding biomarkers within the fiber of the expanding hair shaft. When taken near the scalp, hair can reveal a detection period for alcohol and drugs that extends up to around three months. Hair is straightforward to gather, relatively hard to tamper with, and convenient to transport.
A 1.5-inch portion of roughly 200 hair strands (approximately the thickness of a #2 pencil) closest to the scalp constitutes 100mg of hair, which is the optimum sample for analysis and verification. For EtG, additional tests, and/or analyses beyond 10 panels, 150mg of the sample is advisable. We suggest measuring the sample on a jeweler’s scale. If scalp hair is not present, a comparable amount of body hair can be used. When speaking of head hair, we mean scalp hair solely. Body hair comprises all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four main stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial incorporation of a sample into a laboratory’s framework. This involves confirming the sample was properly sealed and forwarded, allotting a random LAN (Laboratory Accessioning Number), and finishing any supplementary data input not included by an electronic chain of custody system.
Screening comprises an initial rapid examination for substances of abuse. Although Screening offers a budget-friendly approach to exclude drug use in most samples, a positive result in screening requires confirmation to be valid in judicial contexts. Any samples suspected as positive in Screening demand a further confirmation.
If a sample is deemed presumptively positive during Screening, more hair is extracted from the original sample and set aside for Extraction. In this phase, drugs are isolated from hair at a significantly lower concentration than in other techniques (e.g., urine or oral fluid), establishing hair drug screening as the most complex technique to execute.
Confirmation of any preliminary positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if necessary. The entire lab process from Accessioning to Confirmation is examined under the CAP (College of American Pathologists) Hair designation and the accreditation in compliance with ISO / IEC 17025 standards.
