Seen as a pivotal method, hair testing is instrumental in identifying drug and alcohol consumption. It offers an extended history by embedding biomarkers within the hair strand fibers. When strands are gathered near the scalp, they can reveal a detection period of up to 3 months for both alcohol and drugs. Collection is straightforward, tampering is challenging, and shipment is hassle-free.
A sample measuring 1.5 inches, containing around 200 hair strands (roughly matching the thickness of a #2 pencil) near the scalp, yields 100mg—ideal for both screening and confirmation. For EtG, additional testing, or beyond 10-panel testing, 150mg of the specimen is preferred. It's advisable to quantify the specimen using a jeweler's scale. In the absence of scalp hair, a comparable quantity of body hair can be taken. By head hair, we specifically mean scalp hair. Body hair encompasses all other types (including facial, axillary, etc.).
Process Overview
The process in the lab for a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning incorporates the first stage of integrating a sample into the laboratory's system. It involves confirming that the sample remains sealed and shipped correctly, allocating a random LAN (Laboratory Accessioning Number), and concluding any pending data input absent in an electronic chain of custody system.
Screening provides an initial, swift check for drug abuse. Though Screening economically serves to exclude drug presence in most samples, a positive screen mandates confirmation for judicial acceptance. Presumptive positive results in Screening necessitate a follow-up confirmation.
Should the sample test presumptively positive during Screening, additional hair is extracted from the primary specimen for Extraction. This phase retrieves drugs from hair substantially below concentrations found in other techniques (e.g., urine or oral fluid), rendering hair drug testing exceptionally challenging.
Positive screening results undergo Confirmation utilizing GC/MS, GC/MS/MS, or LC/MS/MS. All samples preliminarily positive undergo washing before confirmation as needed. The entire laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair certification and the ISO / IEC 17025 standard accreditation.
