Hair analysis has emerged as a potent method for identifying drug and alcohol usage. It offers a comprehensive timeline of substance intake by encapsulating biomarkers within the strands' fibers as they grow. When hair is taken near the scalp, it can reveal approximately a three-month history of alcohol and drugs. Hair collection is straightforward, challenging to falsify, and easy to transport.
A 1.5-inch hair segment made up of roughly 200 strands (similar to a #2 pencil's thickness) closest to the scalp yields 100mg of hair, the preferred quantity for screening and confirming. For tests on EtG, add-ons, or exceeding 10 panels, 150mg of hair is advised. We suggest measuring the sample with a jeweler's scale. If scalp hair is not an option, the same amount of body hair can be used. When we mention head hair, we mean only scalp hair. Body hair includes all other types (facial, axillary, etc.).
Process Overview
The four primary phases in processing a drug test in the laboratory are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step of incorporating a sample into a lab's framework. It ensures that the sample has been sealed and sent accurately, assigns a random LAN (Laboratory Accessioning Number), and fulfills any extra data input absent from an electronic chain of custody system.
Screening offers an initial rapid assessment for substances of abuse. Though Screening is a budget-friendly method to rule out drug usage on most samples, a positive result must be verified for legal acceptability. All samples that test positive in Screening necessitate a secondary confirmation.
Should a sample test positive in Screening, additional hair is extracted from the original sample and prepared for Extraction. During this phase, drugs are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), explaining why hair drug screening stands as the most challenging method to execute.
Confirmation of any positive screen result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if required. From Accessioning to Confirmation, the entire lab process undergoes a review under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
