Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. Hair strands store a comprehensive history of alcohol and drug intake by capturing biomarkers in the hair fibers as they grow. A sample taken near the scalp can reveal substance use for up to a 3-month period. Hair sample collection is straightforward, challenging to tamper with, and simple to transport.
A measurement of 1.5 inches consisting of roughly 200 hair strands (equivalent in thickness to a #2 pencil) cut near the scalp provides 100mg of hair, which is the optimal amount for both initial testing and confirmation. For EtG, add-on tests, or screenings involving more than 10 panels, a quantity of 150mg is suggested. It's advisable to weigh the sample using a jeweler’s scale. If no scalp hair is available, a comparable quantity of body hair can be used. When mentioning head hair, it refers exclusively to scalp hair. Body hair includes all other types of hair (facial, axillary, etc.).
Process Overview
The laboratory procedure for processing drug test results involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially processed within the laboratory's system. This step involves checking the proper sealing and shipping of the sample, assigning it a random LAN (Laboratory Accessioning Number), and completing any remaining data entry not covered by an electronic chain of custody system.
Screening is an initial rapid assessment to detect drug abuse. Though Screening is an economical approach for excluding drug use in most samples, any positive findings require confirmation for admissibility in legal proceedings. Samples showing presumptive positives in Screening need further confirmation.
In cases of presumptive positives during Screening, additional hair is taken from the initial sample for Extraction. Here, drugs are isolated from hair at a significantly lower concentration compared to other testing methods (such as urine or oral fluid), a reason why hair drug testing is among the hardest methodologies to execute.
Any positive screening results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed before confirmation if needed. The entire lab process, from Accessioning to Confirmation, adheres to CAP (College of American Pathologists) Hair guidelines and complies with ISO / IEC 17025 standards.
