Hair testing is recognized as a robust method for identifying drug and alcohol consumption. Hair offers an extended history of drug and alcohol use by capturing biomarkers within the strands of growing hair. When taken close to the scalp, hair can indicate drug and alcohol use for up to around a 3-month period. Hair collection is straightforward, relatively hard to tamper with, and simple to send.
A 1.5-inch segment of roughly 200 hair strands (comparable to the thickness of a #2 pencil) near the scalp will yield 100mg of the ideal sample for analysis and confirmation. For EtG, additional tests, and/or examinations over 10 panels, a 150mg sample is advised. It's suggested to weigh the sample with a jeweler’s scale. If scalp hair is not an option, a similar amount of body hair may be collected. When mentioning head hair, it refers exclusively to scalp hair. Body hair includes other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial entry of a sample into a lab’s system. This encompasses checking that the sample was appropriately sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry absent in an electronic chain of custody system.
Screening is an initial rapid test for drugs of abuse. While cost-effective for excluding drug usage on most samples, a positive result in Screening requires confirmation for court admissibility. Samples that are moderately positive in Screening necessitate a secondary confirmation.
If a sample tests moderately positive in the Screening phase, additional hair is taken from the initial sample and readied for Extraction. At this stage, drugs are extracted from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), highlighting why hair drug screening is the most challenging method to execute.
Confirming any positive screen result is conducted via GC/MS, GC/MS/MS, or LC/MS/MS. All moderately positive samples are washed before confirmation, as needed. The entire lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
