Hair analysis has emerged as a robust method for detecting substance and alcohol use. The fibers of the hair strand capture biomarkers, providing a prolonged timeline of alcohol and drug exposure. Hair, when collected near the scalp, offers an approximate 3-month detection range for substances. Hair is straightforward to gather, somewhat resistant to tampering, and convenient to transport.
A sample measuring 1.5 inches consisting of roughly 200 strands (comparable to the size of a #2 pencil) taken nearest to the scalp yields 100mg of hair, the optimal sample volume for both screening and confirmation. For EtG testing, additional tests, and/or tests exceeding 10 panels, a quantity of 150mg is advisable. It's recommended to weigh the sample on a jeweler's scale. If scalp hair cannot be collected, an equivalent volume of body hair may be used. The term head hair refers solely to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test outcome comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial integration of a sample into the laboratory's system. This process includes verifying that the sample was securely sealed and properly transported, assigning a unique LAN (Laboratory Accessioning Number), and completing any necessary data entry not provided by an electronic chain of custody system.
Screening involves a preliminary assessment for substances of abuse. Screening is economically efficient for ruling out drug use in most samples, but a positive result requires confirmation for courtroom acceptability. Any samples that show a presumptive positive in Screening require a follow-up confirmation.
If a sample shows a presumptive positive during the Screening phase, additional hair is taken from the specimen for Extraction. This phase entails the extraction of drugs from the hair at much lesser concentrations than found in other sample types (e.g., urine or oral fluid), making hair drug screening the most complex method to perform.
Confirmation of any positive from the screening stage is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if necessary. The entire process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
