Hair testing has emerged as an effective method for identifying drug and alcohol use. Hair captures biomarkers within the strands, offering an extended history of usage. When collected proximally to the scalp, it can provide a detection window of up to three months for drugs and alcohol. Hair is easy to gather, somewhat resistant to tampering, and simple to transport.
A sample measuring 1.5 inches and consisting of roughly 200 strands (about the thickness of a #2 pencil) nearest the scalp yields 100mg of hair, which is the optimal amount for screening and confirmation. For EtG or tests exceeding 10 panels, 150mg of the specimen is advisable. It's suggested to weigh the sample on a jeweler’s scale. If scalp hair cannot be collected, an equivalent amount of body hair is an alternative. Head hair refers specifically to scalp hair. Body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The key stages in the lab processing of a drug test are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial processing phase where a sample is entered into a lab's system, confirming the sample's seal and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not facilitated by an electronic chain of custody system.
Screening is an initial, swift check for drugs of abuse. Though cost-effective for ruling out drug use for most samples, a positive result requires confirmation for court acceptance. Samples that are presumptively positive in Screening must undergo further confirmation.
If a sample shows a presumptively positive result in the Screening phase, additional hair is extracted from the initial sample for further processing in the Extraction phase. Here, drugs are isolated from hair at much lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology.
Confirmation of positive screening outcomes is done using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The entire lab process, from Accessioning to Confirmation, is examined under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO/IEC 17025 standards.
