Hair testing has emerged as a crucial technique for identifying drug and alcohol consumption. By encapsulating biomarkers within the strands of growing hair, it offers a prolonged history of substance use. When collected near the scalp, hair can reveal alcohol and drug presence for up to roughly 90 days. This method is straightforward to collect, relatively hard to tamper with, and convenient for shipping.
A 1.5-inch segment comprising approximately 200 hair strands (roughly the girth of a #2 pencil) nearest to the scalp will achieve a 100mg hair sample, which is optimal for both screening and confirmation. For EtG, additional items, and/or evaluations beyond 10 panels, a specimen of 150mg is advisable. Utilizing a jeweler’s scale for weighing the sample is recommended. In the absence of scalp hair, an equivalent volume of body hair is an alternative. When discussing head hair, it specifically denotes scalp hair. Body hair encompasses all other varieties (including facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result primarily includes four steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial admittance of a sample into a lab's system. This process involves ensuring the sample was properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and finalizing any additional data entry absent in an electronic chain of custody system.
Screening offers a preliminary rapid assessment for substances of abuse. Although Screening efficiently excludes drug usage in a large number of samples, a positive result requires confirmation for legal admissibility. Samples that yield a tentative positive in Screening necessitate a follow-up confirmation.
In cases where a sample shows a presumptive positive at the Screening phase, extra hair is obtained from the original sample for Extraction. During this phase, drugs are extracted from hair at concentrations significantly lower than other approaches (such as urine or oral fluid), rendering hair drug testing one of the most complex methodologies.
Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo necessary washing before confirmation. The comprehensive laboratory procedure, from Accessioning to Confirmation, aligns with both the CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 standards.
