Hair examination has emerged as an effective instrument for identifying substance and alcohol consumption. Hair serves as a historical record of alcohol and drug use by embedding biomarkers in the fibers of the hair strand as it grows. When obtained near the scalp, hair can offer up to roughly a three-month detection period for alcohol and drugs. Hair is easy to gather, fairly resistant to tampering, and convenient to transport.
A 1.5-inch segment of roughly 200 hair strands (approximating the size of a #2 pencil) nearest the scalp will yield about 100mg, the optimal sample needed for screening and confirmation. For EtG, additional tests, and/or analyses beyond 10 panels, 150mg of the sample is advised. Using a jeweler’s scale for specimen weighing is recommended. If scalp hair is not available, a similar quantity of body hair can be gathered. 'Head hair' refers exclusively to scalp hair, whereas 'body hair' pertains to other types of hair (facial, axillary, etc.).
Process Overview
The laboratory evaluation of a drug test result involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning denotes the initial integration of a sample into a laboratory’s framework. This step involves checking if the sample was properly sealed and transported, allocating a random LAN (Laboratory Accessioning Number), and performing any necessary data input not captured via an electronic chain of custody system.
Screening entails a preliminary assessment for detecting drugs of abuse. While Screening is a financially efficient means of eliminating drug presence in most samples, a positive screen result necessitates verification to be lawful in court. Any samples flagged as presumptive positives during Screening require additional confirmation.
When a sample shows a presumptive positive in Screening, additional hair is extracted from the original sample for the Extraction stage. Here, drugs are isolated from hair at a markedly lower concentration than in alternative methods (e.g., urine or oral fluid), making hair drug testing the most challenging type to execute.
Confirmation of any positive screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed prior to confirmation when necessary. The entire lab process from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 benchmarks.
