Detecting drugs and alcohol use through hair testing has emerged as a robust approach. Hair captures a historical record of alcohol and drug consumption by embedding biomarkers within the hair strand's fibers as they grow. When collected near the scalp, hair offers an approximate 3-month detection period for substances. Hair collection is straightforward, tampering is relatively challenging, and it is easily shippable.
A snippet of 1.5 inches of around 200 hair strands (about the size equivalent to a #2 pencil) nearest to the scalp constitutes 100mg, deemed the optimal sample for both screening and confirmation processes. For EtG testing, additional screenings, and tests exceeding 10 panels, a 150mg specimen is advised. It is suggested to weigh the specimen using a jeweler’s scale. If scalp hair isn't accessible, an equivalent mass of body hair can be taken. The term head hair specifically refers to scalp hair only, while body hair includes all other types (such as facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four critical phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning initiates the laboratory's handling of a sample by integrating it into the lab's system. This involves confirming the sample's proper sealing and shipment, assigning an arbitrary LAN (Laboratory Accessioning Number), and finishing any extra data entry not executed by an electronic chain of custody system.
Screening serves as the primary rapid test for potential drug presence. Although Screening provides a cost-effective means to eliminate drug use across most samples, a positive result calls for verification to hold up in court. Screening results indicating presumptive positives necessitate additional confirmation.
For specimens showing presumptive positivity in Screening, further hair is extracted from the original sample and readied for Extraction. In this phase, drug compounds are extracted from hair at notably lower concentrations compared to other processes (such as urine or oral fluid), highlighting the challenges of hair drug screening methodologies.
Confirmation of all positive Screenings is conducted via GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positives undergo pre-emptive washing if needed. The complete laboratory operation, from Accessioning to Confirmation, is assessed under both the CAP (College of American Pathologists) Hair standards and the accreditation to ISO / IEC 17025 benchmarks.
