The use of hair testing has emerged as an effective means for identifying substance and alcohol consumption. Hair can hold biomarkers within its strands, providing a detailed timeline of drug and alcohol use. A sample taken close to the scalp can offer a detection window of up to three months for various substances. Collecting hair is straightforward, challenging to tamper with, and convenient to transport.
Collecting a 1.5-inch sample consisting of around 200 hair strands (approximately the thickness of a pencil) nearest the scalp yields a preferred 100mg for screening and confirmation. For EtG, additional tests, and tests exceeding 10 panels, a sample of 150mg is suggested. It is advisable to measure the specimen using a jeweler’s scale. If scalp hair is inaccessible, a similar quantity of body hair is an option. When discussing head hair, it exclusively refers to scalp hair. Body hair encompasses all other types (beard, underarm, etc.).
Process Overview
There are four crucial stages in processing a drug test laboratory result: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the initial sample handling occurs within the laboratory system. This involves confirming the sample seal and shipping integrity, assigning a Laboratory Accessioning Number (LAN), and completing any additional required data entry absent from an electronic chain of custody.
In the Screening stage, an initial evaluation for drugs of misuse is conducted. Screening is a cost-effective method to eliminate drug usage for most samples. However, for court admissibility, a positive screening requires confirmation. Samples exhibiting presumptive positives during Screening necessitate further confirmation.
For samples testing positive in Screening, an additional sample is sourced for the Extraction stage, where drugs are extracted from hair at significantly lower concentrations than other methods (e.g., urine, saliva), making hair drug screening the most complex methodology.
Utilizing GC/MS, GC/MS/MS, or LC/MS/MS, Confirmation verifies any positive Screening outcomes. Presumptive positive samples are washed before confirmation as necessary. The laboratory process from Accessioning through Confirmation is assessed under the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 standards.
