Hair analysis has gained recognition as an effective method for identifying substance use including alcohol. Hair provides an extended record of substance intake by embedding biomarkers within the strands of hair as it grows. When sampled near the scalp, hair can reveal alcohol and drug use history for roughly a three-month period. Hair collection is straightforward, challenging to tamper with, and convenient for transport.
A segment measuring 1.5 inches and consisting of roughly 200 hair strands (similar in width to a #2 pencil) closest to the scalp yields 100mg of hair—an optimal amount for testing and validation. For EtG examinations, additional and/or tests exceeding 10 panels, 150mg of hair is advisable. Using a jeweler’s scale for specimen measurement is suggested. In the absence of scalp hair, a comparable amount of body hair is acceptable. References to head hair pertain solely to scalp hair. Body hair encompasses all other types such as facial or axillary hair.
Process Overview
The primary phases in the laboratory procedure for processing a drug test result consist of Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the sample's initial processing in a laboratory’s framework. This phase entails confirming proper sealing and shipment of the sample, allocating a random LAN (Laboratory Accessioning Number), and finalizing any additional data entry not supplied by an electronic chain of custody mechanism.
Screening is a preliminary swift procedure to detect drugs of abuse. Although Screening offers an economical approach to exclude drug use in most samples, a positive screen mandates verification for legal compliance. Samples testing presumptively positive require a subsequent confirmation.
Upon presumptive positivity in the Screening phase, extra hair is drawn from the initial sample for preparation in Extraction. Drugs are isolated from hair at significantly lower concentrations than other methods (e.g., urine or saliva), rendering hair drug screening a challenging technique to execute.
Confirmatory tests of any positive screening outcome utilize GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing presumptively positive undergo washing prior to confirmation as necessary. The full laboratory procedure, from Accessioning to Confirmation, is reviewed under the CAP (College of American Pathologists) Hair designation alongside accreditation to ISO / IEC 17025 standards.
