Recognized as an effective means for identifying drug and alcohol consumption, hair testing is a valuable method. Hair captures a historical record of alcohol and drug use by embedding biomarkers within the growing strand. Hair collected from the scalp can reveal drug and alcohol usage history for up to three months. It’s easy to gather, somewhat challenging to tamper with, and convenient to transport.
A sample measuring 1.5 inches, consisting of approximately 200 hair strands (around the size of a #2 pencil), sourced from the scalp, provides the recommended 100mg for screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, using 150mg of hair is advised. We suggest employing a jeweler’s scale for weighing. If scalp hair isn’t obtainable, a comparable portion of body hair might be used. References to head hair specifically mean scalp hair. Body hair comprises any other hair (facial, axillary, etc.).
Process Overview
The laboratory analysis of a drug test result consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.
The Accessioning phase includes the initial receipt of a sample into the laboratory's system. Tasks involve verifying the sample's secure seal and proper shipment, issuing a LAN (Laboratory Accessioning Number) randomly, and any additional data submission needed aside from an electronic chain of custody system.
Screening provides a preliminary check for substances. Though cost-efficient for excluding drug use in most samples, a Screening positive needs further confirmation to be legally defensible. Samples testing positive in Screening necessitate a confirmatory step.
Presumptively positive samples in Screening involve extracting additional hair from the original sample for further processing. Drugs are extracted from hair in this phase at lower concentrations compared to other methods (uri×ne or oral fluid), making hair drug testing challenging and precise.
Confirmation of presumptive positive findings uses techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, necessary samples undergo washing. Auditing the complete procedure—from Accessioning to Confirmation—is conducted based on CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.
