Hair assessments have emerged as an influential means for detecting alcohol and drug consumption. The hair strands capture biomarkers within their fibers, which allows for a prolonged history of substance use to be observed. By securing hair samples near the scalp, it is possible to identify the presence of alcohol or drugs for about a 3-month period. Hair collection is straightforward, somewhat resistant to tampering, and effortless to transport.
A 1.5-inch section, including roughly 200 hair strands (about the thickness of a #2 pencil) nearest to the scalp, can produce a 100mg sample, which is ideal for screening and confirmation procedures. For EtG, add-ons, or tests exceeding 10 panels, a 150mg sample is preferred. It is advisable to measure the sample using a jeweler’s scale. Should scalp hair be unavailable, an equivalent amount of body hair may be gathered. References to head hair pertain only to scalp hair, whereas body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory examination of a drug test result encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary phase in which the sample is integrated into the laboratory’s operations. This step ensures the sample is properly sealed and dispatched, assigns it a Laboratory Accessioning Number (LAN), and completes any supplemental data entry absent from an electronic chain of custody system.
Screening serves as a primary examination for potential drug use. While this is a cost-efficient strategy to eliminate suspicions of drug usage in most samples, a positive result requires further verification to be acknowledged in judicial proceedings. Thus, any presumptively positive sample in Screening demands a follow-up confirmation.
When a sample tests presumptively positive during Screening, additional hair is extracted from the original sample for the Extraction stage. This phase involves retrieving drugs from hair at much lower concentrations than other techniques (ex. urine or oral fluid), emphasizing the complexity of conducting hair drug assessments.
The Confirmation stage for any positive screenings is carried out via methods like GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples undergo a washing process before confirmation as required. The entire lab procedure, from Accessioning to Confirmation, undergoes scrutiny according to both CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation standards.
