Hair testing has emerged as an effective technique for identifying drug and alcohol consumption. By embedding biomarkers within the fibers of hair strands, hair offers an extended retrospective view of alcohol and drug use. When hair is retrieved near the scalp, it can reveal usage of substances for a period of up to around three months. Collecting hair is uncomplicated, somewhat resistant to tampering, and straightforward to transport.
A 1.5-inch portion involving roughly 200 hair strands (equivalent to the diameter of a #2 pencil) nearest to the scalp supplies about 100mg of hair, which serves as the optimal sample size for testing and verification. For EtG, supplementary tests, and/or more than 10-panel tests, a sample of 150mg is advised. It's recommended to measure the weight of the sample using a jeweler's scale. If scalp hair is not present, a comparable amount of body hair can be gathered. References to head hair are solely directed at scalp hair. Body hair encompasses other types of hair (such as facial or axillary).
Process Overview
The key steps associated with laboratory processing of a drug test outcome involve Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial handling of a sample into a lab's system. This process includes confirming the sample was appropriately sealed and delivered, allocating a random Laboratory Accessioning Number (LAN), and finalizing any extra data entry absent in a digital chain of custody system.
Screening comprises a preliminary swift check for substances of abuse. While Screening efficiently rules out drug presence in most samples, any positive indications require confirmation to be legally valid. Samples presumed positive in Screening need subsequent confirmation.
Should a sample test presumptively positive during Screening, additional hair is extracted from the original sample and made ready for Extraction. At this stage, drugs are withdrawn from the hair at much lower concentrations compared to other methods (such as urine or oral fluid), which is why hair drug screening remains the most challenging method to execute.
Confirmation of any positive results from Screening is undertaken using GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicated as presumptively positive are washed before confirmation, when necessary. The full laboratory procedure from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.
