Hair screening is increasingly regarded as a valuable method for identifying substance use. As hair strands grow, they encapsulate biomarkers, offering an extended history of alcohol and drug consumption. When cut close to the scalp, hair can present a detection timeframe reaching nearly 90 days for substances. Its collection is straightforward, it's not easily tainted, and it facilitates easy transportation.
A 1.5-inch segment consisting of roughly 200 hair strands (comparable to a #2 pencil's thickness) from near the scalp yields 100mg, which is optimal for analysis and verification. For EtG, supplementary, and/or tests exceeding 10 panels, 150mg of the sample is advised. Using a jeweler’s scale for weighing the sample is recommended. If scalp hair is not attainable, an equal mass of body hair can be used. References to head hair correspond solely to scalp hair, while body hair pertains to other types such as facial or axillary hair.
Process Overview
The laboratory processing of a drug test result encompasses four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial sample process within a laboratory's system, ensuring the sample was correctly sealed and transported, allocating a random LAN (Laboratory Accessioning Number), and completing any additional data input absent in an electronic chain of custody system.
Screening entails a preliminary assessment for drug abuse. Although Screening offers a cost-efficient means of negating drug use in most samples, a positive result demands confirmation for court admissibility. Presumptive positive samples in Screening necessitate further validation.
In instances of a presumptive positive result during Screening, additional hair is extracted from the original specimen for Extraction. This stage isolates drugs from hair at significantly lower concentrations compared to other approaches (such as urine or oral fluid), highlighting the challenges in hair drug analysis.
Confirmation of any positive screening outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are rinsed prior to confirmation as required. The laboratory procedure from Accessioning through to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation.
