Hair testing is recognized as a robust resource for identifying drug and alcohol consumption. Hair strands encapsulate a biomarker history within the fibers of their growth, allowing for a lengthy timeline of substance use. Hair sampled near the scalp can reveal a 3-month window of drug and alcohol detection. It is straightforward to gather, moderately challenging to tamper with, and straightforward to transport.
A 1.5-inch hair sample, equivalent to roughly 200 strands (comparable to a #2 pencil) near the scalp, yields 100mg, which is the optimal quantity for screening and verification. For EtG, extra tests, and/or screens beyond 10 panels, 150mg is advisable. Utilizing a jeweler's scale for weighing the specimen is suggested. If scalp hair is unavailable, the equivalent amount of body hair is an alternative. When discussing head hair, it pertains only to scalp hair, whereas body hair encompasses other types (facial, axillary, etc.).
Process Overview
The key stages involved in laboratory processing of a drug test include Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the preliminary processing of a sample within a laboratory system, ensuring the sample's seal and shipment are intact, assigning a unique LAN (Laboratory Accessioning Number), and entering any additional information not covered by an electronic chain of custody system.
Screening involves an initial rapid assessment for drug abuse substances. While it is a cost-efficient approach for excluding drug use in most samples, a positive screening necessitates confirmation for legal admissibility. Any samples with presumptive positives in Screening need subsequent confirmation.
Should a sample be marked as presumptively positive during Screening, additional hair is extracted from the initial sample for Extraction. This procedure retrieves drugs from hair at lower concentrations than other methods (such as urine or oral fluid), making hair drug tests the most intricate to execute.
Confirming any positive screening outcomes is carried out via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as required. The complete laboratory procedure, from Accessioning to Confirmation, is reviewed under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
