Hair testing is perceived as an effective method for identifying drug and alcohol consumption. Hair archives a long-term record of substance use by embedding biomarkers within the hair fibers as they grow. When sourced near the scalp, hair offers roughly a 3-month detection period for alcohol and drugs. Collecting hair is straightforward, challenging to alter, and convenient for transport.
A sample of 1.5 inches, containing around 200 hair strands (similar in width to a #2 pencil) near the scalp provides 100mg, which is optimal for both preliminary and confirmatory testing. For EtG, additional analyses, and/or panels exceeding 10, a 150mg specimen is advisable. It is suggested to weigh the sample using a jeweler’s scale. If head hair is absent, a comparable quantity of body hair may be used. The term head hair specifically denotes scalp hair. Other body hairs include facial, axillary, etc.
Process Overview
The laboratory drug testing process encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, samples are entered into the laboratory's database. This process checks if the sample was properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and handles any additional data input not managed by an electronic chain of custody system.
Screening introduces an initial test for drugs. While Screening economically determines drug absence in most cases, any positive findings necessitate confirmation for legal acceptance. Those samples that preliminarily test positive in Screening require additional confirmation.
If a sample shows a presumptive positive result in Screening, extra hair is taken from the original sample for Extraction. This stage extracts drugs from hair at notably lower concentrations than other methods (e.g., urine or oral fluid), which makes hair drug testing exceptionally complex.
Confirmation of a positive result is done using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed before confirmation as necessary. The comprehensive lab procedure from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair standards and the accreditation of ISO / IEC 17025.
