The perception of hair testing has evolved into a recognized method for identifying drug and alcohol consumption. Hair acts as a reservoir for long-term indicators of alcohol and substances by embedding markers within the strands' fibers. When gathered near the scalp, hair can offer up to about a 3-month detection period for alcohol and drugs. Harvesting hair is straightforward, relatively tamper-resistant, and convenient to transport.
A sample of 1.5 inches, comprising around 200 hair strands (approximately the diameter of a #2 pencil), taken closest to the scalp, delivers 100mg of hair, which is the preferred sample size for analysis. For EtG, add-ons, and/or assessments exceeding 10 panels, a specimen amounting to 150mg is advisable. Utilizing a jeweler’s scale for weighing the sample is suggested. If scalp hair is not available, a comparable collection of body hair can be obtained. "Head hair" specifies only scalp hair, while "body hair" includes all other categories (facial, axillary, etc.).
Process Overview
There are four fundamental stages in the lab processing of a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into a laboratory framework. It encompasses confirming the proper sealing and shipping of the sample, generating a random LAN (Laboratory Accessioning Number), and finalizing any supplemental data entry missing from an electronic chain of custody protocol.
Screening comprises a preliminary, brisk evaluation for substance abuse. While Screening provides an economical method to exclude drug consumption for the bulk of samples, a positive screen necessitates validation for legal acceptance. Any samples flagged as presumptively positive in Screening mandate a follow-up confirmation.
In scenarios where a sample appears positive during Screening, additional hair is extracted from the original specimen and readied for Extraction. At this juncture, drugs are isolated from hair in concentrations notably lower than alternative systems (e.g., urine or oral fluid), establishing hair drug testing as the most complex procedure to conduct.
Confirmation of a positive screening outcome is achieved using GC/MS, GC/MS/MS, or LC/MS/MS methods. All initial positive samples undergo washing pre-confirmation when essential. The comprehensive laboratory operations, from Accessioning to Confirmation, are conducted per both the CAP (College of American Pathologists) Hair directive and the compliance standards of ISO / IEC 17025.
