Hair tests have gained recognition as an effective method for uncovering drug and alcohol consumption. Hair offers an extended history of alcohol and drug markers by locking them within the developing hair fibers. When harvested close to the scalp, hair can reveal drug and alcohol use for up to a 3-month period. Its collection is straightforward, it's challenging to tamper with, and it is simple to transport.
A hair sample, typically 1.5 inches with around 200 strands (or roughly as thick as a #2 pencil) nearest the scalp yields 100mg, the preferred amount for analysis and validation. For EtG, additional panels, and/or tests exceeding 10 panels, it's suggested to gather 150mg. It's advised to measure the sample on a jeweler’s scale. If scalp hair isn't available, an equivalent quantity of body hair can be collected. "Head hair" refers exclusively to scalp hair, whereas "body hair" covers all other types (such as facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is about integrating a sample into the laboratory system. This encompasses confirming the sample's sealing and shipping integrity, assigning it a unique LAN (Laboratory Accessioning Number), and completing any additional data documentation not managed by an electronic chain of custody system.
Screening performs an initial assessment for drugs of abuse. While it's a budget-friendly approach to exclude drug use in most cases, positive findings in Screening need validation for court acceptance. Samples flagged as positive during Screening require further confirmation.
For samples deemed positive during Screening, additional hair is drawn from the initial sample and set for Extraction. Here, substances are extracted from hair at concentrations much lower than other methods (e.g., urine or oral fluid), making hair drug screening notably challenging.
Confirmation for any positive Screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples considered presumptive positives undergo a washing process before confirmation, as required. The entire laboratory sequence from Accessioning to Confirmation is rigorously reviewed both under the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.
