Hair testing is regarded as an effective tool for identifying drug and alcohol use. Hair offers a prolonged history of alcohol and other drugs by capturing biomarkers within the hair strand's fibers as it grows. When collected near the scalp, hair can reveal up to an approximate 3-month detection period for alcohol and other substances. Hair's ease of collection, resistance to tampering, and straightforward shipping make it advantageous.
A 1.5-inch sample consisting of about 200 hair strands (comparable to a #2 pencil in thickness) nearest to the scalp yields 100mg of hair, the preferred sample for testing and verification. For EtG, add-ons, or tests beyond 10 panels, a 150mg sample is advisable. It's suggested to weigh the sample on a jeweler’s scale. If scalp hair isn't available, an analogous quantity of body hair is suitable. Regarding head hair, we strictly refer to scalp hair. Body hair encompasses all other hair categories (facial, axillary, and so forth).
Process Overview
The laboratory processing of a drug test outcome involves four principal steps: Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, the initial sample processing into a lab’s system occurs. This step includes confirming the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry not covered by an electronic chain of custody system.
Screening serves as a preliminary rapid check for substance abuse. Although Screening economically rules out drug usage for most samples, a positive screen necessitates confirmation for legal admissibility. Samples showing presumptive positives in Screening need subsequent confirmation.
Should a sample yield a presumptive positive during Screening, additional hair is extracted from the initial sample for the Extraction phase. Here, drugs are isolated from hair at a much lower concentration than alternative techniques (e.g., urine or oral fluid), positioning hair drug screening as a complex methodology to execute.
Confirmation of any positive screen result is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, presumptive positive samples undergo necessary washing. The entire lab process from Accessioning to Confirmation undergoes scrutiny under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
