Hair analysis is increasingly regarded as an effective method for detecting substance use. This form of testing offers a long-term record of drug and alcohol usage by capturing biomarkers within the fibers of the growing hair. When taken adjacent to the scalp, hair samples can reveal drug and alcohol consumption spanning up to around three months. Collecting hair is straightforward, challenging to tamper with, and convenient to transport.
A sample length of 1.5 inches consisting of roughly 200 hairs (similar in thickness to a #2 pencil) nearest to the scalp will yield 100mg, which is the optimal amount for both testing and verification. For testing categories such as EtG, enhancements, and/or more than 10-panel tests, 150mg of the hair is advised. Using a jeweler’s scale for weighing specimens is recommended. If scalp hair is not available, a comparable amount of body hair can be utilized. Here, head hair refers strictly to scalp hair. All other hair types (such as beard or underarm) are considered body hair.
Process Overview
The lab processing of a drug test result involves four principal stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the initial handling of a specimen within a lab's workflow, ensuring proper sealing and transportation, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any additional data entry that an electronic custody chain hasn’t supplied.
Screening provides a rapid test for drug abuse. This stage helps efficiently exclude drug usage in most cases, though a verified result is mandatory for legal contexts. Any sample testing positive in the initial Screening demands a follow-up confirmation.
When a sample yields a positive Screening outcome, extra hair is retrieved from the original batch and prepared for Extraction. At this stage, substances are removed from hair at significantly lower concentrations compared to other test types (such as urine or oral samples), which renders hair drug screening notably complex.
Positive test results from Screening must undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples indicated as positive in Screening are cleansed as required before Confirmation. The entire lab process from Accessioning to Confirmation complies with CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 standards.
