Seen as an influential method, hair testing is beneficial for identifying drug and alcohol consumption. By capturing biomarkers within the fibers, hair chronicles the consumption of alcohol and drugs. A sample taken near the scalp can show usage up to three months prior. Hair is easy to gather, challenging to tamper with, and convenient to transport.
A 1.5-inch portion made up of around 200 strands near the scalp provides 100mg, the optimal specimen size. For EtG, extensions, and/or analyses beyond a 10-panel test, 150mg is suggested. Using a jeweler’s scale to measure the sample is advised. Should scalp hair be missing, a similar quantity of body hair is acceptable. The term scalp hair refers specifically to head hair, whereas body hair encompasses other kinds (like facial, axillary, etc.).
Process Overview
Drug test result processing in the lab entails four key phases: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a specimen enters into the lab's framework. This process confirms the integrity of the sample’s seal and shipment, assigns a unique Laboratory Accessioning Number (LAN), and executes any supplementary data entry absent in an electronic chain of custody system.
The Screening phase offers a rapid assessment for drug traces. While cost-efficient to eliminate drug use in many samples, any positive screen necessitates verification for court usage. Any specimen showing presumptive positivity will need additional confirmation.
If Screening identifies a sample as presumptively positive, more hair is extracted from the initial sample for further preparation in Extraction. Drugs are isolated from hair at notably lower concentrations compared to other techniques (such as urine or oral fluid), marking hair drug screening as the most demanding methodology.
Confirmation of positive Screening outcomes occurs via GC/MS, GC/MS/MS, or LC/MS/MS techniques. Necessary presumptive positive samples undergo washing before confirmation. The comprehensive lab procedure from Accessioning to Confirmation complies with the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.
