The role of hair testing has become significant in identifying the use of drugs and alcohol. Hair offers an extensive timeline of drug and alcohol consumption by embedding biomarkers within the fibers of the hair as it grows. When collected near the scalp, it can reveal drug and alcohol use over the past three months. Collecting hair is straightforward, challenging to tamper with, and simple to transport.
A sample measuring 1.5 inches, comprising roughly 200 hair strands (similar to a #2 pencil's width) from the scalp yields 100mg, which is perfect for screening and confirmation. When testing for EtG, add-ons, and/or more than 10 drug panels, 150mg of hair is advisable. It is suggested to weigh the sample using a jeweler’s scale. If scalp hair isn’t available, a comparable amount of body hair can be used. References to head hair pertain only to scalp hair. Body hair includes all other varieties (facial, axillary, etc.).
Process Overview
The primary steps in processing a drug test result in the lab are Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, the sample is initially processed into the lab's system. This step ensures the sample was properly sealed and shipped, assigns a unique LAN (Laboratory Accessioning Number), and addresses any further data entry not recorded by an electronic chain of custody system.
Screening involves a quick initial assessment for substances of abuse. While this step is economical for eliminating the possibility of drug use in most samples, a positive Screen must be validated for court use. Any presumptive positives from Screening need a follow-up confirmation.
For samples marked as presumptively positive during Screening, additional hair is taken from the original sample for Extraction. During Extraction, drugs are extracted at much lower concentrations than in other methods (e.g., urine or oral fluid), making hair drug screening a challenging methodology.
Positive results from Screening undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed prior to necessary confirmations. The entire lab process from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
