Hair analysis is recognized as an effective means to identify drug and alcohol consumption. It provides a prolonged history of substance use by capturing biomarkers within the growing strands. When obtained near the scalp, it offers up to a three-month detection period for alcohol and drugs. The collection is straightforward, hard to tamper with, and simple to transport.
A sample measuring 1.5 inches, consisting of around 200 hair strands (the thickness of a #2 pencil), yields 100mg - the perfect amount for tests and confirmation. For EtG, add-on tests, or those exceeding 10 panels, 150mg is advisable. We suggest using a jeweler's scale for specimen measurement. If scalp hair isn't accessible, the same quantity of body hair can be collected. 'Head hair' denotes only scalp hair, whereas 'body hair' encompasses other types (facial, axillary, etc.).
Process Overview
The four key stages in drug test result processing in the lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the sample's integration into the lab's system initially. It includes ensuring the sample is correctly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any data entry missing from an electronic chain of custody system.
Screening performs a quick preliminary test for substance abuse. While cost-efficient for ruling out drug use in most cases, a positive screen needs confirmation to be legally admissible. Samples that test presumptively positive in Screening require a confirmatory test.
If Screening indicates a presumptive positive, more hair is taken from the initial sample and prepared for Extraction. Here, substances are extracted from hair at much lower levels than other methods (e.g., urine or oral fluid), making hair drug screening the most difficult method.
Confirmation of positive screening outcomes is carried out via GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples undergo washing if required. The whole process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair program and ISO / IEC 17025 standards.
