Hair testing is now recognized as a significant method for identifying drug and alcohol consumption. It offers a prolonged record of substance use by preserving biomarkers within the fibers of hair strands as they grow. When gathered near the scalp, hair can reveal substance use for as long as a three-month duration. The process of hair collection is straightforward, hard to tamper with, and convenient to transport.
A segment of hair measuring 1.5 inches with approximately 200 strands (equivalent to a #2 pencil's size) close to the scalp equates to 100mg, which is the perfect amount for both screening and confirmation. For EtG, additional tests, or testing exceeding 10 panels, a sample of 150mg is advised. Utilizing a jeweler's scale for measuring the sample is suggested. If scalp hair is not available, an equivalent quantity of body hair can be used. When mentioning head hair, we specifically mean scalp hair. Body hair encompasses all other hair types, including facial and axillary hair.
Process Overview
The laboratory processing of a drug test result encompasses four main steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial integration of a sample into the laboratory's system. This step includes checking that the sample is properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and finishing any supplementary data entry not covered by an electronic chain of custody system.
Screening is a preliminary examination for substances of abuse. It is a cost-efficient method to eliminate drug use in most samples; however, a positive result in Screening must be substantiated to be valid in legal proceedings. Any samples with a presumptive positive result in Screening require further confirmation.
Should a sample show a presumptive positive during Screening, additional hair is utilized from the original sample and set up for Extraction. During this phase, substances are removed from hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), explaining why hair drug screening is one of the most challenging methods to execute.
Confirmation of any positive result from Screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before being confirmed as necessary. The complete laboratory procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
