Recognized as a significant method, hair testing is instrumental in identifying drug and alcohol consumption. It captures long-term data on such substances by preserving biomarkers within the hair strand's fibers. When cut near the scalp, hair can reveal a detection period of roughly three months for drugs and alcohol. Its collection is straightforward, tampering proves challenging, and it's easily transportable.
A sample measuring 1.5 inches and consisting of approximately 200 hair strands (around the thickness of a #2 pencil) near the scalp yields 100mg, which is optimal for screening and verification. For EtG, supplementary tests, and/or those exceeding 10 panels, a 150mg sample is advised. Using a jeweler's scale is recommended for weighing the specimen. In the absence of scalp hair, an equivalent quantity of body hair can be used. "Head hair" refers explicitly to scalp hair, while "body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
The primary phases in laboratory handling of drug test results include Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially processed within a laboratory's framework, ensuring it was properly sealed and shipped, a random LAN (Laboratory Accessioning Number) is assigned, and any additional data entry not captured by an electronic chain of custody system is completed.
Screening involves a preliminary assessment for drugs of abuse. While Screening effectively excludes drug use for most samples, a positive result requires confirmation for judicial acceptability. Presumed positive samples in the Screening phase necessitate further confirmation.
If a sample is reportedly positive in the Screening phase, further hair is sourced from the original specimen for the Extraction phase. Here, drugs are retrieved from hair at significantly low concentrations compared to other methodologies (e.g., urine or oral fluid), making hair drug screening notably complex.
Positive Screening results are confirmed via GC/MS, GC/MS/MS, or LC/MS/MS. Suspected positive samples are cleansed ahead of confirmation as required. The complete lab process from Accessioning to Confirmation adheres to both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
