Hair testing has emerged as an effective means for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and drug presence by embedding biomarkers within the strands as they grow. When procured near the scalp, hair can represent a detection period of roughly three months for both alcohol and drugs. Hair collection is straightforward, not easy to tamper with, and simple to transport.
Obtaining a 1.5-inch snippet consisting of approximately 200 hairs (comparable to the thickness of a #2 pencil) near the scalp will yield about 100mg, which is optimal for screening and verifying results. For EtG, additional tests, or when exceeding 10 panels, 150mg is advised. Using a jeweler’s scale is recommended for weighing the sample. If scalp hair is not present, an equivalent quantity of body hair can be collected. When referencing head hair, it pertains exclusively to scalp hair. Body hair includes all other hair types (facial, axillary, etc.).
Process Overview
There are four key stages in the laboratory handling of a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the initial assimilation of a sample into a lab's database. It verifies the sample was correctly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and concludes any outstanding data input absent from an electronic chain of custody system.
Screening entails an initial rapid analysis for substance abuse. While Screening is a cost-efficient method for excluding drug use in most samples, a positive result requires confirmation to be valid in legal venues. Any samples yielding a tentative positive result in Screening need subsequent verification.
If a sample shows a potential positive result during Screening, more hair is extracted from the original specimen for the Extraction process. In this stage, drugs are drawn from hair at a significantly diminished concentration compared to other methods (e.g., urine or oral fluid), marking hair drug screening as the most challenging method to execute.
Confirmation of any positive screen outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All suspected positive samples undergo cleaning before confirmation when necessary. The entire lab process from Accessioning to Confirmation adheres to the CAP (College of American Pathologists) Hair guidelines and complies with ISO / IEC 17025 accreditation standards.
