Hair analysis is recognized as an effective method for detecting alcohol and drug use. It offers a comprehensive history of substance intake by capturing biomarkers within the hair strand's fibers. When collected near the scalp, hair can demonstrate a detection span of approximately three months for both alcohol and drugs. Hair collection is straightforward, resistant to tampering, and convenient for transport.
Using a sample size of 1.5 inches with roughly 200 strands (comparable to a #2 pencil width) nearest to the scalp will yield 100mg of hair, which is the optimal quantity for testing and verification. For tests such as EtG, additional panels, or those exceeding 10 panels, a 150mg sample is advised. It's best to weigh the sample with a jeweler’s scale. In the absence of scalp hair, an equivalent amount of body hair may be used. Note that head hair specifically refers to scalp hair, while body hair encompasses all other hair types (such as facial or axillary hair).
Process Overview
There are four primary phases in the lab processing of a drug test: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial integration of a sample into the laboratory's records. This step includes ensuring the sample was adequately sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any missing data entry not covered by an electronic chain of custody system.
Screening serves as an initial assessment for drug presence. Although Screening is cost-effective for excluding drug use in most samples, confirmation is necessary for any legal proceedings. Any samples with presumptive positive results in Screening must undergo further confirmation.
Should a sample test positive at the Screening stage, additional hair is extracted from the original sample and prepared for Extraction. In this phase, drugs are drawn from hair at a notably lower concentration compared to other techniques (e.g., urine or oral fluids), which makes hair drug testing one of the most challenging methodologies.
Confirmation of positive results from Screening is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Any samples with presumptive positive results are cleansed before confirmation if required. The comprehensive laboratory procedure, from Accessioning to Confirmation, is examined following both the CAP (College of American Pathologists) Hair accreditation and the ISO / IEC 17025 standards.
