Hair testing is recognized as a significant method for identifying drug and alcohol consumption. Hair captures biomarkers in the strands' fibers, offering a comprehensive record of substance use over time. When taken near the scalp, it can reveal a usage timeline of up to roughly three months. Hair collection is straightforward, not easily tampered with, and simple to transport.
A 1.5-inch segment of approximately 200 hair strands (about the size of a #2 pencil) near the scalp provides 100mg, the optimal specimen size for testing and verification. For EtG, additional substances, or panels exceeding 10, 150mg of the sample is advised. It's suggested to use a jeweler’s scale for weighing. If scalp hair isn't available, an equivalent portion of body hair can be used. Head hair refers specifically to scalp hair, whereas body hair encompasses all other types (facial, axillary, etc.).
Process Overview
Key phases in the lab analysis of a drug test are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step, involving entering the sample into the lab's system. This step ensures the sample’s secure sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and involves any extra data entry not covered by an electronic chain of custody.
Screening offers a fast, economical test for substance abuse. Although effective for the majority of samples, a confirmed result is necessary for legal proceedings. Any samples that test presumptively positive during Screening must undergo further confirmation.
If the Screening stage indicates a presumptively positive result, additional hair is extracted and readied for the Extraction stage. At this point, drugs are isolated from the hair at lower concentrations than in alternative methods (e.g., urine or oral fluid); thus, hair drug screening is notably challenging.
Positive results from the Screening process are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples are cleansed before confirmation if necessary. The entire lab process, from Accessioning to Confirmation, complies with the CAP (College of American Pathologists) Hair guidelines and ISO/IEC 17025 accreditation standards.
