Hair analysis is now recognized as an effective means for detecting drug and alcohol consumption. Hair retains a comprehensive history of alcohol and drugs by embedding biomarkers within the strands' fibers as they grow. When samples are closely gathered from the scalp, this can offer a detection period extending up to around three months for both alcohol and other substances. Hair collections are straightforward, resistance to tampering, and conveniently transportable.
A 1.5-inch segment comprising approximately 200 hair strands, akin in size to a typical #2 pencil, cut nearest to the scalp, yields 100mg of hair, which is optimal for both screening and verification processes. For EtG, additional checks, or tests exceeding 10 panels, a sample weight of 150mg is suggested. Using a jeweler’s scale for measuring the sample is advisable. In cases where scalp hair is not present, an equivalent volume of body hair can be used. Note that when mentioning head hair, it strictly refers to scalp hair, whereas body hair includes all other types (such as facial, axillary, and more).
Process Overview
Hair drug testing encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially registered into the system of a lab. This step includes checking the proper sealing and shipping of the sample, the allocation of an arbitrary LAN (Laboratory Accessioning Number), and the completion of any extra data input not managed by an electronic chain of custody system.
The Screening phase involves a preliminary, rapid assessment for drugs of abuse. While it offers an affordable means to eliminate most drug use suspicions, a positive outcome requires confirmation to stand in court. Any sample deemed presumptively positive in Screening demands further confirmation.
Should a sample yield a presumptively positive result during Screening, additional hair is taken from the primary specimen and prepped for Extraction. This phase involves the extraction of drugs from hair at a notably reduced concentration compared to other methods (such as urine or oral fluid), highlighting why hair drug testing is particularly challenging to execute.
To confirm any positive screening results, techniques like GC/MS, GC/MS/MS, or LC/MS/MS are utilized. All samples that are initially positive are cleansed before the confirmation process if necessary. The complete laboratory procedure—from Accessioning through Confirmation—is audited under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
