Hair testing is increasingly recognized as a robust tool for identifying drug and alcohol consumption. Hair captures a historical record of alcohol and drug exposure by embedding biomarkers within the fibers of the hair as it grows. Collected close to the scalp, hair can offer a detection timeframe of up to about three months for alcohol and other drugs. Hair collection is straightforward, relatively challenging to tamper with, and simple to transport.
Obtaining a 1.5-inch sample consisting of around 200 hair strands (approximately the thickness of a #2 pencil) near the scalp yields 100mg, the ideal quantity for both screening and confirmation tests. For EtG, add-ons, and/or tests exceeding 10 panels, it is advisable to gather 150mg of the specimen. We advise using a jeweler’s scale to measure the specimen weight. If scalp hair is unavailable, a comparable amount of body hair can be gathered. By head hair, we mean scalp hair exclusively. Body hair refers to all other hair varieties (facial, axillary, etc.).
Process Overview
The laboratory analysis of a drug test sample involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a lab’s system. It involves ensuring the sample was properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not provided by an electronic chain of custody setup.
Screening involves an initial swift assessment for drugs of abuse. While Screening is a budget-friendly method to rule out drug usage in most samples, a positive screen warrants confirmation to be deemed admissible in legal settings. Any samples showing a presumptive positive in Screening require further confirmation.
Should a sample test presumptively positive during Screening, additional hair is retrieved from the original specimen and readied for Extraction. This stage involves extracting drugs from hair at a much lower concentration than other methods (e.g., urine or oral fluid), which is why hair drug screening is among the most intricate methodologies to perform.
Confirmation of any positive screen result is done using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed before confirmation if needed. The end-to-end lab process from Accessioning to Confirmation is overseen under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
