Hair analysis is increasingly recognized as a robust method for identifying drug and alcohol consumption. Hair captures a prolonged usage history by securing biomarkers within its strands. When cut near the scalp, hair can offer roughly a three-month detection window for alcohol and other substances. It’s straightforward to collect, with limited opportunities for tampering, and simple to transport.
A sample measuring 1.5 inches and consisting of approximately 200 hair strands (akin to a #2 pencil in thickness) near the scalp yields 100mg, which is optimal for screening and confirmation processes. For EtG, add-on tests, or assessments exceeding ten panels, a sample size of 150mg is advised. We suggest weighing the sample on a jeweler’s scale. If no scalp hair is available, an equivalent amount of body hair can be used. By head hair, we mean only scalp hair. Body hair encompasses all other hair types (such as facial, axillary, etc.).
Process Overview
The laboratory work for a drug test result comprises four essential stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step of processing a sample into the lab system. This step ensures the sample was sealed and sent correctly, assigns it a random LAN (Laboratory Accessioning Number), and completes any extra data input not supplied by an electronic chain of custody system.
Screening involves a rapid initial check for illicit substances. While Screening cost-effectively excludes drug usage in most cases, any positive results need confirmation for court proceedings. Samples testing presumptively positive in Screening necessitate additional verification.
For samples testing presumptively positive during Screening, extra hair is extracted from the initial sample for the Extraction phase. In this phase, drugs are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug testing a more challenging methodology to execute.
Any positive screens are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumptively positive receive a wash prior to confirmation as required. The complete laboratory workflow, from Accessioning to Confirmation, is assessed under both the CAP (College of American Pathologists) Hair criteria and ISO/IEC 17025 accreditation standards.
