Hair testing has gained recognition as an effective means for identifying drug and alcohol use. Hair strands offer a long-lasting record of alcohol and other drugs by capturing biomarkers within the growing hair's fibers. A sample collected near the scalp can reveal drug or alcohol usage for up to around a 3-month period. Hair is easy to obtain, hard to tamper with, and simple to transport.
Gathering a 1.5-inch segment of approximately 200 hairs (comparable to a #2 pencil) near the scalp yields 100mg of hair, which is optimal for analysis and verification. For EtG, additional tests, and/or panels beyond 10, 150mg of the sample is advised. It is suggested to weigh the sample using a jeweler's scale. If scalp hair is not an option, a similar amount of body hair can be taken. When discussing head hair, we specifically mean scalp hair. Body hair refers to all other hair types (facial, axillary, etc.).
Process Overview
The key phases in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step of incorporating a sample into a lab’s system. This involves confirming that the sample was properly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not available from an electronic chain of custody system.
Screening is a preliminary assessment for drug abuse. Though Screening is an economical way to dismiss drug use in most samples, a positive result must be confirmed for legal acceptance. Any samples that yield a presumptive positive in Screening need secondary confirmation.
Should the sample test presumptively positive during Screening, more hair is extracted from the original specimen to prepare for Extraction. During this phase, drugs are removed from hair at a significantly lower concentration than other methods (e.g., urine or oral fluid), making hair drug screening the most challenging method to undertake.
Confirmation of any positive screening result is accomplished using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results undergo washing before confirmation as required. The complete lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
