Hair testing stands recognized as a potent method for identifying drug and alcohol consumption. Hair strands capture long-term substance use by securing biomarkers within the fibers as the hair strand develops. Sourced near the scalp, hair has the potential to reveal substance use over roughly a 3-month window. Collecting hair is straightforward, hard to manipulate, and convenient to transport.
A 1.5-inch segment made up of around 200 hair strands (equivalent to the width of a #2 pencil) from the scalp yields 100mg of hair, an ideal quantity for testing and verification. For EtG, supplemental tests, or tests above 10 panels, a specimen size of 150mg is suggested. It's advisable to weigh the specimen using a jeweler’s scale. In cases where scalp hair is missing, a comparable quantity of body hair could be used. The term head hair refers solely to scalp hair, while body hair includes all other hair types (like facial, axillary, etc.).
Process Overview
The crucial steps in the laboratory journey of a drug test result encompass Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample undergoes its first processing phase in a lab’s system. This step covers ensuring the sample was appropriately sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any missing data entry not covered by an electronic chain of custody system.
Screening serves as an initial rapid assessment for drugs of abuse. Screening is an economical approach to negate drug use in most samples; however, a positive screening mandates confirmation for court viability. Any samples preliminarily positive in Screening need further confirmation.
Should a sample test preliminarily positive in Screening, additional hair is extracted from the initial sample for the Extraction phase. During this phase, drugs are retrieved from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening the most challenging method to execute.
Confirmation for any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptive positive sample undergoes washing before confirmation if necessary. The complete lab procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.
