Hair testing has gained recognition as a robust method for detecting drug and alcohol usage. Hair offers a prolonged history of substance use by capturing biomarkers within the fibers of the growing hair strand. When taken near the scalp, hair can provide a detection timeframe of up to roughly 3 months for alcohol and other drugs. Hair is easy to collect, hard to tamper with, and simple to ship.
A 1.5-inch portion of around 200 hair strands (approximately the diameter of a #2 pencil) nearest to the scalp will yield 100mg of hair, the optimal sample for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the hair sample is advised. It's suggested to weigh the sample using a jeweler’s scale. If scalp hair is absent, a similar quantity of body hair may be gathered. When discussing head hair, we specifically mean scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The process of analyzing a drug test result in a laboratory involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial processing phase where a sample is entered into a laboratory system. It entails ensuring the sample was sealed and transported correctly, assigning a random LAN (Laboratory Accessioning Number), and completing additional data entry if not provided by an electronic chain of custody.
Screening conducts a preliminary rapid check for drug abuse. While Screening is an inexpensive way to eliminate drug use in the majority of samples, a positive screen must be verified for court admissibility. Samples showing positive indications during Screening require further confirmation.
If a sample tests positive during the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. In the Extraction phase, drugs are isolated from hair at a significantly lower concentration than in other methods (e.g., urine or oral fluid), making hair drug testing the most challenging procedure to execute.
Confirmation of any positive Screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo washing before confirmation if needed. The entire lab process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
