Assessing hair has emerged as a significant means in identifying drug and alcohol consumption. The hair strands contain a historical account of alcohol and substance use by encapsulating biomarkers within the hair fibers as they develop. When procured near the scalp, hair can reveal a detection window of up to roughly 3 months for alcohol and drugs. It is easy to gather, hard to tamper with, and convenient to ship.
A 1.5-inch hair fragment with approximately 200 hairs (about the thickness of a #2 pencil) nearest the scalp will yield 100mg, the optimal quantity for analysis and validation. For EtG, supplements, and/or assessments exceeding 10 panels, a 150mg sample is advised. It's advisable to measure the sample utilizing a jeweler’s scale. In the absence of scalp hair, an equivalent measure of body hair may be gathered. When mentioning head hair, it strictly denotes scalp hair. Body hair pertains to all other categories (facial, axillary, etc.).
Process Overview
The primary phases included in the lab processing of a drug test are Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the preliminary examination of the sample within the lab’s framework. This step ensures the sample’s seal and shipment were intact, assigns a random LAN (Laboratory Accessioning Number), and fills any further data gaps not covered by a digital chain of custody system.
Screening executes an initial rapid evaluation for substance abuse. While Screening offers an economical avenue to negate drug use in most samples, a detected positive requires confirmation for court acceptance. Samples preliminarily positive in Screening necessitate secondary confirmation.
For a sample preliminarily positive at the Screening point, more hair is extracted from the original sample and poised for Extraction. Drugs are drawn from hair at significantly lower concentrations compared to alternative methodologies (e.g., urine or oral fluid), which renders hair drug analysis particularly intricate.
To confirm any positive detected result, methods such as GC/MS, GC/MS/MS, or LC/MS/MS are used. Presumptive positive samples are cleansed prior to confirmation as required. The comprehensive lab procedure, from Accessioning to Confirmation, undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation as well as the ISO / IEC 17025 accreditation standards.
