Hair testing is increasingly recognized as a robust method for identifying drug and alcohol use. Hair effectively captures long-term evidence of alcohol and drugs by embedding biomarkers within the fibers of the growing strand. When taken near the scalp, the hair offers a detection window extending up to around 3 months for alcohol and other substances. Hair collection is straightforward, relatively resistant to tampering, and uncomplicated to transport.
A sample measuring 1.5 inches and consisting of roughly 200 hair strands (comparable in size to a #2 pencil) closest to the scalp results in 100mg of hair, which is optimal for screening and verification. For EtG, additional analyses, and/or tests exceeding 10 panels, a specimen weighing 150mg is suggested. We advise measuring the sample on a jeweler’s scale. If scalp hair is absent, a comparable quantity of body hair might be taken. The term head hair denotes scalp hair exclusively. Body hair implies all other hair varieties (facial, axillary, etc.).
Process Overview
The primary procedures involved in the laboratory evaluation of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial handling of a sample into a lab’s system. This process ensures the sample is correctly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes any supplemental data entry not included in an electronic chain of custody system.
Screening involves a preliminary rapid assessment for drugs of abuse. Despite Screening being an economical method to eliminate drug use in most samples, a positive screen necessitates confirmation to be valid in legal contexts. Any samples that are provisionally positive in Screening require further confirmation.
If a specimen appears positive during the Screening phase, additional hair from the original sample is extracted for the Extraction stage. Here, drugs are isolated from hair at significantly lower concentrations than other techniques (e.g., urine or oral fluid), making hair drug screening the most challenging approach to execute.
Confirmation of any positive screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are tentatively positive undergo washing before confirmation as required. The entire lab process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.
