Hair sampling is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair retains a lengthy record of alcohol and drug intake by capturing biomarkers within the hair strand as it grows. When collected near the scalp, hair may offer a detection window of up to three months for alcohol and other drugs. The process of obtaining hair samples is straightforward, with minimal risk of tampering, and the samples can be easily transported.
A 1.5-inch sample consisting of roughly 200 strands of hair (comparable in size to a #2 pencil) taken from the scalp region will yield 100mg, which is the optimal quantity for screening and confirmation. For tests such as EtG, add-ons, and/or those exceeding 10 panels, a specimen of 150mg is advised. It is recommended to utilize a jeweler’s scale for accurately weighing the sample. If scalp hair cannot be obtained, a similar quantity of body hair may be used. The term "head hair" pertains solely to scalp hair, whereas "body hair" encompasses all other hair types (such as facial and axillary hair).
Process Overview
The laboratory processing of a drug test encompasses four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial integration of a sample into a lab's system. This phase ensures that the sample was adequately sealed and shipped, allocates a unique LAN (Laboratory Accessioning Number), and completes any supplementary data entry not available through an electronic chain of custody.
Screening serves as an initial assessment for the presence of drugs of abuse. While it is a cost-efficient method to exclude drug use in most samples, a positive screening result necessitates confirmation for legal admissibility. Any samples preliminarily positive in Screening must undergo secondary confirmation.
In instances where a sample indicates a presumptive positive in the Screening phase, additional hair is extracted from the original specimen and prepared for Extraction. This phase involves extracting drugs from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), rendering hair drug screening one of the most challenging techniques to execute.
Positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing presumptive positives are cleansed prior to confirmation as necessary. The comprehensive laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair standard and accreditation to ISO / IEC 17025 norms.
