Within recent years, hair testing has emerged as a significant method to identify drug and alcohol consumption. By trapping biomarkers within the fibers of a growing hair strand, hair provides an extended history of substance use. When taken near the scalp, it can offer up to roughly a 3-month period for detection of both alcohol and other substances. Hair is easy to gather, relatively hard to tamper with, and straightforward to transport.
Gathering a 1.5-inch sample containing about 200 strands of hair (roughly equivalent to a #2 pencil's width) nearest the scalp yields 100mg of hair, which is the preferred amount for both screening and confirmation. For EtG, supplementary tests, or analyses beyond 10 panels, a 150mg specimen is suggested. It's advised to measure the sample on a jeweler’s scale. If head hair isn't available, a similar amount of body hair can be used as an alternative. When mentioning head hair, we specifically mean scalp hair. Body hair encompasses all other hair forms (like facial, axillary, etc.).
Process Overview
The laboratory processing of drug test results encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the sample's entry into a lab's system. This phase includes checking that the sample was sealed and shipped correctly, assigning a unique LAN (Laboratory Accessioning Number), and inputting any extra data not captured by an electronic chain of custody method.
Screening provides an initial rapid drug check. Even though Screening is an economical approach to eliminate drug usage for most samples, a verified positive result is necessary for court acceptability. Samples deemed presumptively positive in Screening need a follow-up confirmation.
If Screening results in a presumptive positive, additional hair is sourced from the original sample for Extraction. This phase extracts drugs from hair at lower concentrations than techniques like urine or oral fluid testing, making hair drug screening a particularly challenging methodology.
Confirmation for any positive screening result is done using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, each presumptive positive sample is washed when needed. The comprehensive lab process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and with accreditation to ISO / IEC 17025 standards.
