Hair analysis is now regarded as an effective method to uncover drug and alcohol consumption. The hair strands retain drug-related markers within their fibers, offering a comprehensive timeline of substance use. When hair is taken near the scalp, it can reveal a drug and alcohol consumption history stretching up to three months. The procedure for hair collection is straightforward, with tampering posing more of a challenge, and it can be easily transported.
A hair sample, measuring 1.5 inches in length with around 200 strands (comparable to the thickness of a #2 pencil), collected nearest to the scalp, equates to 100mg, which is suitable for initial screening and follow-up testing. For EtG, add-ons, and/or screenings beyond 10 panels, 150mg is suggested. It's advisable to use a jeweler’s scale for weighing the sample. If scalp hair cannot be obtained, a matching quantity of body hair might be used. When referencing head hair, it specifically means scalp hair. Body hair refers to all other types of hair (e.g., facial, axillary).
Process Overview
The primary stages in processing a drug test at a laboratory are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step where samples are logged into the laboratory's system. This phase includes verifying that the sample's seal and shipment were handled correctly, allocating a random Laboratory Accessioning Number (LAN), and completing any extra details not included via the electronic chain of custody system.
Screening serves as a preliminary check for potential drug abuse. While cost-effective for ruling out drug usage in many samples, any positive result from Screening needs verification for legal considerations. Samples indicative of drug presence in Screening require confirmatory testing.
Should a Screening test show a presumptive positive, further hair is taken from the original sample for Extraction. This stage involves drawing drugs from hair at significantly lower concentrations compared to other testing methods like urine or oral fluid, which is why hair analysis is considered highly challenging.
Any presumptive screen positive must be validated using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, necessary cleaning is performed. The entire transition from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair criteria and adheres to ISO / IEC 17025 standards.
