Hair testing is increasingly regarded as an effective method for identifying drug and alcohol consumption. Hair can capture biomarkers in its fibers, offering a prolonged record of alcohol and drug use. By collecting hair near the scalp, it provides a detection window for up to about three months for alcohol and drugs. The collection of hair is straightforward, challenging to tamper with, and simple to transport.
A 1.5-inch segment of roughly 200 hair strands (similar in size to a #2 pencil) cut closely at the scalp provides 100mg of hair, which is ideal for testing and verification. For EtG, additional checks, and/or tests covering more than 10 drug panels, a recommendation of 150mg samples is suggested. We advise measuring the sample using a jeweler’s scale. If scalp hair is not available, comparable body hair may be collected. References to head hair pertain solely to scalp hair. Body hair encompasses other types (e.g., facial, axillary).
Process Overview
The lab processing for drug tests encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial sample processing within the lab’s system. It involves ensuring the sample is properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any missing data not captured by an electronic chain of custody system.
Screening offers a quick check for drug use. Although cost-effective for ruling out drug use in most samples, a positive screen must be confirmed for court admissibility. Samples that are potentially positive during Screening need further confirmation.
If a sample appears presumptively positive during Screening, additional hair is taken for Extraction. In this stage, drugs are extracted from hair at lower concentrations compared to other methodologies (e.g., urine or oral fluid), making hair drug screening more challenging to execute.
Confirmation for any positive screening result occurs using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing pre-confirmation if necessary. The entire process from Accessioning to Confirmation is reviewed under CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
