Hair analysis is recognized as a potent method for detecting alcohol and drug usage. Hair strands offer a comprehensive history of substance exposure by embedding biomarkers within their fibers. When sourced near the scalp, hair can offer an approximate 3-month detection timeframe for alcohol and drugs. Hair is straightforward to gather, somewhat resistant to tampering, and simple to transport.
A 1.5-inch sample comprising roughly 200 hair strands (about the diameter of a #2 pencil) from near the scalp yields 100mg, which is the perfect amount for screening and confirmatory purposes. For EtG, add-ons, and/or tests exceeding 10 panels, a 150mg specimen is advised. It's best to weigh the sample on a jeweler’s scale. If scalp hair isn’t available, an equal volume of body hair is acceptable. "Head hair" refers specifically to scalp hair, while "body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory process for drug testing consists of four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where a sample is integrated into the lab’s system. This includes confirming the sample was properly sealed and delivered, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary data entry absent from an electronic chain of custody system.
Screening offers a preliminary examination for substance abuse. Screening is an economical approach to eliminate drug use suspicion in most samples, but a positive result requires further confirmation for legal validity. Samples with presumptive positive results during Screening must undergo additional confirmation.
If the Screening stage indicates a presumptive positive result, further hair is extracted from the initial sample for the Extraction phase. Here, substances are drawn from the hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening the most intricate technique to conduct.
Confirmation of any positive screening is accomplished through GC/MS, GC/MS/MS, or LC/MS/MS. Samples presumptively positive are washed prior to confirmation as needed. The full laboratory process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.
