Hair analysis is increasingly recognized as an effective method for detecting drug and alcohol consumption. The composition of hair records a prolonged history of substance use by capturing biomarkers within the hair fibers as they grow. When sourced near the scalp, hair offers a detection window for alcohol and drugs of up to about three months. It's easy to collect, challenging to tamper with, and straightforward to transport.
Collecting a 1.5-inch segment of roughly 200 hair strands (comparable to a #2 pencil) nearest the scalp provides 100mg of hair, the perfect quantity for screening and analysis. For EtG, additional tests, and/or tests exceeding 10 panels, it's advised to collect 150mg of the sample. Utilizing a jeweler’s scale to weigh the hair sample is recommended. If head hair isn't available, an equivalent amount of body hair can be acquired. When we discuss head hair, it refers solely to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The key stages in laboratory processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the initial entry of a sample into a lab's system. This process ensures the sample was sealed and transported correctly, assigns a random LAN (Laboratory Accessioning Number), and finishes any required data entry missing from an electronic chain of custody system.
Screening entails a preliminary quick evaluation for drugs. Despite being a cost-efficient method to eliminate drug use in the majority of samples, a positive result requires confirmation for admissibility in court. Any samples that return a presumptive positive during Screening need further, confirmatory testing.
In cases where a sample is presumptively positive at the Screening phase, additional hair is retrieved from the original specimen and prepared for Extraction. In this segment, drugs are withdrawn from hair at a notably lower concentration compared to other methods (e.g., urine or oral fluid), highlighting why hair drug testing is the most intricate approach.
To verify any positive screening outcome, techniques like GC/MS, GC/MS/MS, or LC/MS/MS are employed. All samples deemed presumptive positive are cleaned prior to confirmation as needed. The comprehensive lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation standards.
