Hair analysis has emerged as a potent means for detecting drugs and alcohol. Hair offers a prolonged record of alcohol and drugs by locking biomarkers within its fibers during growth. When taken near the scalp, it can extend to roughly a 3-month detection period for alcohol and drugs. Hair is easy to collect, hard to tamper with, and simple to transport.
A 1.5-inch section of around 200 hair strands (similar to a #2 pencil) nearest to the scalp provides 100mg, the optimal amount for analysis and confirmation. For EtG, additional tests, and those exceeding 10 panels, 150mg is advised. We suggest measuring the sample on a jeweler’s scale. If head hair is absent, a similar quantity of body hair can be used. Head hair refers solely to scalp hair. Body hair includes all other types (facial, axillary, etc.).
Process Overview
The primary steps in the lab processing of drug testing are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails incorporating a sample into a lab's system. This encompasses verifying the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing additional data entry as needed.
Screening involves a preliminary inspection for drugs. Although Screening is cost-effective for ruling out drug use in most cases, a confirmed result is necessary for court admission. Samples that test positive in Screening require secondary confirmation.
Should a sample be positive in Screening, more hair is taken from the original sample for Extraction, where drugs are withdrawn from hair at lower concentrations than other methods (e.g., urine or saliva). This makes hair drug screening one of the most challenging methodologies.
Confirmation of positive screening results is done using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives are washed before confirmation if needed. The complete laboratory process, from Accessioning to Confirmation, is reviewed under both CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
