Hair testing is recognized as an effective method for detecting drug and alcohol consumption. Hair strands can capture biomarkers within their fibers, providing a long-term record of alcohol and drug usage. When hair is collected near the scalp, it offers around a three-month window for detecting alcohol and other drugs. Collection is easy, alteration is challenging, and shipping is straightforward.
An ideal sample for analysis consists of a 1.5-inch segment with approximately 200 strands (comparable to a #2 pencil) closest to the scalp, yielding 100mg of hair. For EtG, additional analytes, or tests exceeding 10 panels, 150mg of hair is advised. It's best to measure the sample using a jeweler's scale. If scalp hair is unavailable, the same amount of body hair can be used. When mentioning head hair, it refers exclusively to scalp hair, while body hair includes all other types (facial, axillary, etc.).
Process Overview
The primary steps in processing a drug test outcome in the lab are Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes initial processing within the lab's system, which involves verifying the sample was sealed and transported correctly, assigning a LAN (Laboratory Accessioning Number), and completing necessary data entry absent from an electronic chain of custody method.
Screening provides an initial, rapid examination for drug abuse. Screening is cost-efficient for ruling out drug use in most samples, but a positive result requires confirmation for legal admissibility. Presumptively positive samples during Screening demand secondary confirmation.
If a sample shows presumptive positivity in the Screening stage, more hair is extracted from the original specimen for Extraction. Here, drugs are isolated from hair at a lower concentration level than other methods (such as urine or oral fluid), making hair drug testing one of the most complex methodologies.
Positive screening results are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation as needed. The overall lab process from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
