Hair analysis has emerged as a potent instrument for detecting drug and alcohol use. By capturing biomarkers within the fibers of a growing hair strand, hair offers a prolonged history of drug and alcohol consumption. When obtained near the scalp, it can present up to a 3-month detection period for these substances. Hair collection is straightforward, resistant to tampering, and easy to transport.
A 1.5-inch segment of roughly 200 hair strands (approximately the size of a #2 pencil) nearest to the scalp will yield 100mg of hair, the optimal quantity for screening and confirmation. For EtG, additional tests, or tests beyond 10 panels, a suggestion of 150mg is made. Utilizing a jeweler’s scale for weighing the specimen is advised. Should scalp hair be inaccessible, an equivalent portion of body hair might be collected. When mentioning head hair, only scalp hair is implied. Body hair encompasses all other hair types (such as facial, axillary, etc.).
Process Overview
The laboratory procedure for processing a drug test result encompasses four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the sample's initial processing into a laboratory system. This process incorporates confirming that the sample was properly sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and completing any supplementary data input not available through an electronic chain of custody system.
Screening represents a preliminary, swift check for drug abuse. While Screening affords a cost-efficient approach to dismiss drug use in the majority of samples, to be permissible in legal settings, a positive screen must be verified. Samples that show a presumptive positive during Screening need a follow-up confirmation.
When a sample tests presumptively positive in the Screening phase, additional hair is extracted from the initial specimen and readied for Extraction. This phase involves extracting drugs from the hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), illustrating why hair drug screening is the most intricate technique to administer.
Confirmation for any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are cleaned as needed. The comprehensive laboratory operation from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the accreditation per ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Commonly referred to as "hair follicle tests", the examination targets the hair strand itself, not the sub-scalp hair follicle.
