Hair testing has emerged as a significant method for identifying drug and alcohol usage. Hair captures a prolonged history of alcohol and drug consumption by holding biomarkers within the fibers of the progressing hair strand. When hair is collected near the scalp, it can reflect up to a roughly three-month detection period for alcohol and drugs. Hair is easy to collect, somewhat resistant to tampering, and straightforward to transport.
Gathering a 1.5-inch sample of around 200 hair strands (comparable to a #2 pencil) closest to the scalp yields 100mg of hair, which is optimal for screening and verification. For EtG, additional tests, or tests exceeding 10 panels, 150mg of the sample is advisable. Measuring the sample using a jeweler’s scale is suggested. If head hair is unavailable, a similar quantity of body hair can be collected. In discussing head hair, we refer exclusively to scalp hair. Body hair encompasses all other hair types (facial, underarm, etc.).
Process Overview
The four key stages in the lab processing of drug test outcomes are Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial handling of a sample within a laboratory’s protocol. This involves confirming that the sample was correctly sealed and shipped, allotting an arbitrary LAN (Laboratory Accessioning Number), and completing additional data recording not included in an electronic chain of custody system.
Screening executes an initial rapid check for abusive substances. Although Screening is a budget-friendly approach to exclude drug usage for the majority of samples, a positive screen must be substantiated to be legally acceptable. Any samples that are provisionally positive in Screening necessitate a secondary validation.
Should a sample appear presumptively positive during the Screening phase, additional hair is extracted from the initial sample and prepped for Extraction. Herein, drugs are harvested from hair at a considerably reduced concentration than other methods (e.g., urine or oral fluid), which is why hair drug testing is the most challenging procedure.
Verification of positive screening outcomes is performed via GC/MS, GC/MS/MS, or LC/MS/MS. Every provisionally positive sample is cleansed prior to confirmation as required. The complete laboratory process from Accessioning through Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
