Hair examinations have been recognized as a robust approach for identifying drug and alcohol consumption. Hair offers an extended-term account of alcohol and other drugs by capturing biomarkers within the growing hair strand's fibers. When procured near the scalp, hair can offer up to around a 3-month detection window for alcohol and other substances. Hair is straightforward to gather, relatively hard to tamper with, and simple to mail.
A section of 1.5 inches consisting of roughly 200 hair strands (approximately matching the diameter of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal sample size for evaluation and verification. For EtG, supplementary tests, and/or testing beyond 10 panels, 150mg of the sample is suggested. We recommend using a jeweler's scale for weighing the specimen. If scalp hair cannot be accessed, a comparable quantity of body hair may be utilized. Reference to head hair specifically addresses scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test outcome comprises four main steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the initial handling of a sample into the lab's system. This involves confirming the sample was properly sealed and dispatched, the allocation of a random LAN (Laboratory Accessioning Number), and completing missing data entry not covered by an electronic chain of custody system.
Screening is a preliminary rapid assessment for substance misuse. Although Screening is a budget-friendly option to exclude drug usage in most samples, a positive screen necessitates further confirmation to be court-acceptable. Samples that are tentatively positive in Screening demand additional confirmation.
Should a sample be tentatively positive in Screening, further hair is extracted from the original specimen and prepped for Extraction. This stage entails extracting drugs from hair at a notably reduced concentration than alternate methods (such as urine or oral fluid), which is why hair drug screening is recognized as the most challenging method to conduct.
Positive screening results undergo Confirmation using GC/MS, GC/MS/MS or LC/MS/MS. Every presumptive positive sample is cleansed before confirmation when necessary. The full lab process from Accessioning to Confirmation undergoes review under the scrutiny of the CAP (College of American Pathologists) Hair designation and accreditation per ISO / IEC 17025 standards.
