Hair testing is increasingly recognized as an effective means for detecting drug and alcohol consumption. Hair strands retain biomarkers within the fibers as they grow, offering a long-term record of alcohol and drug use. When hair is collected near the scalp, it can reveal alcohol and drug use over a timeframe of up to about three months. Hair is easy to collect, not easily altered, and simple to transport.
A sample size of 1.5 inches, comprising approximately 200 hair strands (comparable to a #2 pencil), nearest to the scalp yields around 100mg of hair, the preferred amount for both screening and confirmation. For EtG, add-ons, and/or more comprehensive tests beyond 10 panels, 150mg of the specimen is suggested. It's advisable to measure the specimen's weight using a jeweler’s scale. If scalp hair is unavailable, a comparable quantity of body hair can be collected. References to head hair specifically mean scalp hair. Body hair encompasses all other types of hair (e.g., facial, axillary, etc.).
Process Overview
The lab processing of drug test results involves four main phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of processing a sample initially into the lab's system. This process verifies the proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any missing data entries not provided through an electronic chain of custody system.
Screening involves a preliminary assessment for drugs of abuse. Screening is a cost-efficient way to eliminate drug usage in most samples; however, a positive screening must be confirmed for legal admissibility. Samples that are initially positive in Screening require secondary confirmation.
If Screening results are presumptively positive, additional hair is extracted from the initial sample to prepare it for Extraction. In Extraction, drugs are isolated from hair at concentrations considerably lower than those in other methods (e.g., urine or oral fluid), which makes hair drug screening the most challenging methodology to execute.
Confirmation of any positive screening is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing before confirmation if necessary. The comprehensive lab procedure from Accessioning to Confirmation is examined according to both the CAP (College of American Pathologists) Hair designation and the standards accredited to ISO / IEC 17025.
