Hair testing is widely regarded as an effective means of identifying alcohol and drug usage. Hair provides a chronology of substance use by trapping biomarkers within the fibers of the advancing hair strand. When cut close to the scalp, it can offer up to a 3-month timeframe for the detection of alcohol and drugs. Collection is straightforward, difficult to tamper with, and convenient for transportation.
A 1.5-inch hair strand sample, approximately 200 strands thick (comparable to a #2 pencil size) taken near the scalp, yields 100mg, which is ideal for screening and validation. For EtG, additional tests, or tests exceeding 10 panels, a 150mg specimen is advisable. Using a jeweler’s scale for weighing is suggested. If scalp hair is unavailable, an equivalent amount of body hair can be used. When mentioning head hair, it refers specifically to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves Accessioning, Screening, Extraction, and Confirmation as the primary phases.
Accessioning pertains to the initial sample processing within a laboratory’s system. This process includes verifying the sample’s secure sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and executing any further data entry absent in an electronic chain of custody system.
Screening is an initial, rapid evaluation for drug abuse. Despite Screening’s cost-effectiveness in dismissing drug use in most samples, court admissibility requires a positive screen’s confirmation. Presumptive positives in Screening necessitate secondary confirmation.
Should a sample be presumptively positive during Screening, extra hair is taken from the initial sample for Extraction. Here, drugs are extracted from hair at notably lower concentrations than in other methods (e.g., urine or oral fluid), making hair drug screening the most complex method to perform.
Confirmation of any positive screening result occurs using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing before confirmation if needed. The complete laboratory process, from Accessioning to Confirmation, is audited under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
