The utilization of hair testing has emerged as a significant method for identifying drug and alcohol consumption. Hair offers an extended timeline for detecting alcohol and other substances, as biomarkers are caught within the fibers of developing hair strands. When collected near the scalp, hair can offer approximately a three-month window for detecting alcohol and other substances. Hair samples are straightforward to acquire, relatively hard to tamper with, and convenient to send.
Collecting a 1.5-inch sample of around 200 hair strands (roughly the size of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal quantity for both screening and confirmation. For EtG tests, additional screenings, and panels beyond 10, a 150mg sample is advised. Measuring the sample with a jeweler's scale is also recommended. If scalp hair is not accessible, an equivalent quantity of body hair can be collected. When we mention head hair, we refer solely to scalp hair, while body hair includes all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of drug test results primarily involves four stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially processed within the laboratory’s system. It involves ensuring that the sample was properly sealed and sent, assigning it a unique LAN (Laboratory Accessioning Number), and completing any extra data entry absent from an electronic chain of custody system.
Screening is a preliminary rapid evaluation for drugs of abuse. Although it's economical for ruling out drug usage in most samples, a positive screen must be confirmed to be considered valid in legal contexts. Samples that test presumptively positive in Screening must undergo a secondary confirmation.
If a sample shows a presumptive positive in the Screening phase, more hair is extracted from the initial sample for the Extraction phase. Here, drugs are obtained from hair at a considerably lower concentration than with other methods (for example, urine or saliva), making hair drug testing the most challenging to perform.
Confirmation of any positive screen is carried out using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positives undergo washing before confirmation if required. The complete laboratory process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.
