Hair testing has emerged as an effective means of detecting drug and alcohol consumption. Hair captures a long-term record of these substances by embedding biomarkers within the growing hair strand's fibers. Collected near the scalp, it can indicate alcohol and drug use over roughly a 3-month span. It's straightforward to collect, not easily tampered with, and simple to transport.
A 1.5-inch sample comprising roughly 200 strands (around the thickness of a #2 pencil) near the scalp provides 100mg of hair, the preferred amount for testing and confirmation. For EtG, additional screenings, and extensive panel tests above 10, 150mg is the advised amount. Use a jeweler’s scale to measure. Should scalp hair be inaccessible, similar quantities of body hair can be used. "Head hair" denotes only scalp hair. "Body hair" covers all other types (facial, axillary, etc.).
Process Overview
The procedure for lab processing of a drug test includes four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage of incorporating a sample into a lab's framework. This step verifies the proper sealing and shipping of the sample, assigns it a random LAN (Laboratory Accessioning Number), and concludes with any remaining data entry that the electronic custody system hasn't completed.
Screening gives a preliminary assessment for drug use. While it efficiently rules out drug consumption for most samples, any positive results from this stage must be confirmed for legal admissibility. Presumptively positive samples here lead to a secondary confirmation.
Upon a presumptive positive indication during Screening, additional hair is extracted from the initial sample for the Extraction phase. Here, drugs are isolated from hair at much lower concentrations than methods like urine or oral fluid testing, making hair drug screening particularly challenging.
GC/MS, GC/MS/MS, or LC/MS/MS procedures confirm any positive Screening outcomes. Samples testing presumptively positive undergo washing before Confirmation, as necessary. Each laboratory procedure from Accessioning to Confirmation is cross-referenced under both the CAP (College of American Pathologists) guidelines and conformity with ISO / IEC 17025 standards.
