Hair testing has advanced as an efficient means for identifying drug and alcohol consumption. Hair encapsulates a timeline of alcohol and drug use by embedding biomarkers within the strands during growth. When taken near the scalp, it offers around a three-month scope for detecting alcohol and various drugs. Hair collection is straightforward, fairly resistant to tampering, and easy to transport.
A 1.5-inch segment of roughly 200 hair strands (comparable to a #2 pencil thickness) from the scalp provides 100mg, the perfect quantity for analysis. For EtG, additional tests, or panels over 10, a sample of 150mg is preferred. Utilizing a jeweler's scale to weigh the sample is advised. If scalp hair isn't present, an equivalent amount of body hair can be used. By "head hair," we mean exclusively scalp hair, whereas "body hair" encompasses other hair types (facial, axillary, etc.).
Process Overview
The laboratory stages for processing a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the sample's initial entry into a lab’s records, confirming it was sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and inputting any additional data not available through an electronic custody process.
Screening is a preliminary examination for substance use. It’s a cost-efficient measure for excluding drug use in most samples, but any positive findings require confirmation before being deemed courtworthy. Any initially positive samples need further confirmation.
When a sample is marked positive in Screening, more hair is extracted and prepared for Extraction. Here, drugs are isolated from hair at lower concentrations than in other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug testing.
Positive screening results are validated via GC/MS, GC/MS/MS or LC/MS/MS. Samples with assumed positive results are cleansed before confirmation if necessary. The full lab process from Accessioning to Confirmation is inspected under CAP (College of American Pathologists) Hair criteria and is ISO / IEC 17025 accredited.
