Hair testing is recognized as a significant method for identifying drug and alcohol consumption. Hair acts as a long-term record of alcohol and other substances by capturing biomarkers within the fibers of growing hair. When hair is gathered near the scalp, it offers a detection range of up to around three months for alcohol and other drugs. Hair collection is straightforward, relatively tamper-resistant, and conveniently transportable.
A sample measuring 1.5 inches with approximately 200 hair strands (roughly the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, suitable for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, a specimen weighing 150mg is advisable. We suggest measuring the specimen on a jeweler’s scale. If scalp hair isn't available, an equivalent volume of body hair can be collected. When speaking of head hair, it pertains solely to scalp hair. Body hair includes all other varieties (facial, axillary, etc.).
Process Overview
The laboratory processing stages of a drug test result consist of Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial handling of a sample within a laboratory’s system. This step involves ensuring the sample was securely sealed and properly shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any requisite data entry absent in an electronic chain of custody system.
Screening involves a preliminary assessment for drugs of abuse. It is a cost-effective method to exclude drug use in most samples, but a positive screening result must be confirmed for court admissibility. Samples presumed positive in Screening require additional confirmation.
If a sample shows a presumptive positive in the Screening stage, more hair is taken from the original specimen and prepared for Extraction. This phase involves extracting drugs from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), which contributes to hair drug testing being the most challenging methodology to execute.
Confirmation of a positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are washed as necessary. The entire laboratory workflow from Accessioning to Confirmation is reviewed under the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.
