Over time, hair testing has gained recognition as an effective means of identifying drug and alcohol consumption. Hair archives the presence of alcohol and drugs by encapsulating biomarkers within the fibers of the progressively growing hair. When obtained near the scalp, hair can reveal drug and alcohol usage within a nearly 3-month timeframe. Hair is straightforward to obtain, challenging to tamper with, and convenient to transport.
A 1.5-inch section, consisting of roughly 200 hair strands (comparable in thickness to a #2 pencil) closest to the scalp, provides 100mg of hair, which is the optimal amount for initial screening and verification. For EtG, additional tests, and examinations exceeding 10 panels, a specimen weighing 150mg is advised. It is recommended to measure the specimen with a jeweler's scale. If scalp hair is absent, a corresponding amount of body hair might be used. References to head hair specifically indicate scalp hair. Body hair pertains to all other varieties (facial, axillary, etc.).
Process Overview
The key phases in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes initial handling within a lab's framework. This consists of ensuring the sample is properly sealed and transported, allotting a random LAN (Laboratory Accessioning Number), and finalizing any supplemental data entry absent from an electronic chain of custody setup.
Screening involves an introductory swift analysis for substance abuse. Screening is an economical approach to exclude substance consumption for most specimens; however, a positive screen must be verified to be legally permissible. Any specimens showing tentative positivity in Screening necessitate a follow-up confirmation.
If a specimen is tentatively positive in the Screening phase, additional hair is extracted from the original specimen and prepped for Extraction. In this stage, drugs are isolated from hair at a considerably lower concentration than other techniques (for instance, urine or oral fluid), thus making hair drug screening a challenging methodology to conduct.
Verification of any positive screening outcome occurs through GC/MS, GC/MS/MS, or LC/MS/MS. All preliminary positive specimens are cleansed before confirmation as needed. The complete laboratory procedure from Accessioning to Verification is examined under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 benchmarks.
