Utilizing hair for testing is now regarded as an effective method for identifying the consumption of drugs and alcohol. Within the fibers of the growing hair shaft, hair captures biomarkers, offering an extensive history of alcohol and other drugs. When cut near to the scalp, hair can reveal a detection period of approximately three months for both alcohol and other substances. Hair is straightforward to gather, somewhat tough to alter, and simple to transport.
A 1.5-inch segment consisting of around 200 hair strands (comparable to a #2 pencil in thickness) adjacent to the scalp will yield 100mg of hair, considered the optimal sample for both testing and confirmation. For EtG, additional tests, and/or examinations that exceed 10 panels, it is advisable to obtain 150mg of the sample. We suggest measuring the sample using a jeweler’s scale. If scalp hair is not available, a similar amount of body hair may be acquired. When we mention head hair, it exclusively refers to scalp hair. Body hair includes other types of hair (such as facial, axillary, etc.).
Process Overview
In the lab, four principal steps are pivotal in processing a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step in incorporating a sample into the lab’s system. It entails checking that the sample was properly sealed and sent, generating a unique LAN (Laboratory Accessioning Number), and performing any extra data input not offered by an electronic chain of custody.
Screening entails an initial brisk examination for illicit substance consumption. Though Screening provides an economical method to dismiss drug intake in most specimens, any positive findings require confirmation to be legally acceptable. Samples that show presumptive positive results in Screening indeed require subsequent validation.
If Screening indicates a presumptive positive, additional hair is extracted from the original sample and readied for Extraction. In this phase, substances are retrieved from hair at a substantially lesser concentration compared to other methods (e.g., urine or saliva), making hair drug analysis one of the most challenging processes to execute.
Positive results from Screening are validated using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples showing presumptive positive outcomes are cleansed before Confirmation, as needed. The entire laboratory workflow, from Accessioning to Confirmation, undergoes review according to both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
