Hair analysis is increasingly viewed as a robust method for detecting drug and alcohol consumption. By trapping biomarkers within the fibers of hair as it grows, it can offer an extensive history of alcohol and other substances. When gathered from near the scalp, the hair sample can reveal substance use over a roughly 3-month span. This method is straightforward to collect, relatively hard to tamper with, and simple to transport.
A 1.5-inch segment of around 200 hairs (approximately the thickness of a #2 pencil) near the scalp equates to 100mg of hair, which is ideal for both screening and confirmation. For tests like EtG, add-ons, or those exceeding 10 panels, it's advisable to use 150mg of the specimen. A jeweler’s scale is suggested for weighing the sample. If scalp hair is unavailable, a comparable amount of body hair can be used. 'Head hair' pertains solely to scalp hair, whereas 'body hair' includes all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result includes four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves integrating the sample into a lab's system. This step checks that the sample was appropriately sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any leftover data entry absent from an electronic chain of custody system.
Screening conducts an initial swift assessment for substance abuse. Though Screening offers a cost-effective method to eliminate drug use in most samples, any positive results must be confirmed for legal admissibility. Presumptively positive samples in Screening require a follow-up confirmation.
If the Screening phase suggests a positive result, additional hair is taken from the original sample for the Extraction process. This step isolates drugs from hair at a much lower concentration than other techniques (like urine or oral fluid), underscoring the complexity of hair drug analysis.
Confirmation of any screening results indicating positivity is done via GC/MS, GC/MS/MS, or LC/MS/MS. If necessary, all presumptive positive samples are cleaned before confirmation. The whole lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
