Hair screening is recognized as an effective measure for identifying drug and alcohol consumption. Hair can offer a lengthy history of alcohol and drug use by capturing biomarkers within the shafts of the growing hair. When taken near the scalp, hair can reveal evidence of alcohol and drug use for up to three months. Hair collection is straightforward, challenging to alter, and easy to dispatch.
A sample measuring 1.5 inches and comprising around 200 hair strands (approximately the thickness of a #2 pencil) nearest to the scalp provides 100mg, which is optimal for analysis and verification. For EtG, supplementary tests, or tests exceeding 10 panels, 150mg of the hair is advised. It is best to weigh the hair on a jeweler's scale. If scalp hair cannot be sourced, equivalent body hair may be used. When specifying head hair, we mean scalp hair solely. Body hair encompasses any other hair types (like facial and underarm hair).
Process Overview
The four fundamental stages involved in processing a drug test in the lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial entry of a sample into the lab system. This includes checking that the sample was properly sealed and transported, generating a random LAN (Laboratory Accessioning Number), and completing additional data entry absent in an electronic chain of custody system.
Screening carries out an initial drug abuse check. This screening method economizes while eliminating drug use among most samples; however, a screen showing positive must be confirmed for legal acceptance. Samples indicating a positive result in Screening need a confirmation follow-up.
For any presumptive positive at Screening, additional hair is extracted from the initial sample for the Extraction phase. Here, drugs are extracted from hair at lower concentrations compared to other methods (for example, urine or saliva), making hair drug testing the most intricate routine to execute.
Any positive results from screening are verified using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive specimens are cleansed before confirmation as necessary. The complete lab process from Accessioning to Confirmation undergoes evaluation according to CAP (College of American Pathologists) Hair standards and accreditation to the ISO / IEC 17025 criteria.
