Hair testing is recognized as a potent method for identifying drug and alcohol consumption. Hair captures biomarkers within the strands of the growing hair, offering a prolonged record of alcohol and other drugs. When taken near the scalp, hair can reveal drug and alcohol use for up to about three months. Collecting hair is straightforward, with minimal chance for tampering, and it can be easily transported.
A sample measuring 1.5 inches, consisting of approximately 200 hair strands (roughly the diameter of a #2 pencil) taken closest to the scalp, yields 100mg of hair, which is the optimal amount for screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a sample of 150mg is suggested. It is advisable to weigh the sample using a jeweler’s scale. If scalp hair is absent, a similar amount of body hair can be collected. When we refer to head hair, it pertains solely to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The key stages in the laboratory analysis of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial incorporation of a sample into a laboratory’s system. This step ensures the sample’s seal and shipment were handled correctly, allocates a random LAN (Laboratory Accessioning Number), and completes any further data entry that is absent from an electronic chain of custody system.
Screening offers a preliminary, swift assessment for drugs of abuse. Even though Screening is economically efficient for negating drug usage in most samples, confirmed results are essential for court admissibility. Any Screening results that indicate presumptive positivity necessitate further Confirmation.
For samples showing presumptive positivity in the Screening phase, additional hair is extracted from the original sample and readied for Extraction. In Extraction, drugs are isolated from hair at significantly reduced concentrations compared to other techniques (e.g., urine or oral fluid), which makes hair drug screening the most challenging method to execute effectively.
Confirmation of any positive screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are cleansed appropriately. The thorough laboratory operation—from Accessioning through Confirmation—is examined under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
