Hair analysis is increasingly recognized as a robust means for identifying drug and alcohol consumption. Hair strands capture a historical record of drug use by embedding biomarkers in the filamentous structure as they grow. Samples near the scalp offer a detection period nearing three months for drugs and alcohol. Hair collection is straightforward, hard to tamper with, and convenient for shipping.
A section of hair measuring 1.5 inches, comprising about 200 strands (approximately the girth of a #2 pencil) near the scalp, yields 100mg, the optimal amount for analysis. For EtG, supplementary tests, and tests exceeding 10 panels, a 150mg sample is suggested. Utilization of a jeweler’s scale is advised for specimen weighing. If scalp hair is inaccessible, equivalent body hair may be procured. "Head hair" pertains solely to scalp hair, while "body hair" includes other types (e.g., facial, axillary hair).
Process Overview
The laboratory handling of drug test outcomes involves four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a sample within the laboratory framework. This phase includes verifying proper sealing and shipment of the sample, allocating a random LAN (Laboratory Accessioning Number), and finalizing any residual data entry absent from an electronic custody chain system.
In Screening, a swift initial assessment for drug abuse occurs. Screening economically eliminates drug usage in most samples, yet positive results must be confirmed to remain valid in legal contexts. Presumptively positive screenings necessitate further confirmation.
Should Screening suggest a positive result, additional hair is extracted from the initial sample for Extraction. This stage isolates drugs from hair at concentrations lower than other methods (e.g., urine or oral fluids), rendering hair drug screening particularly complex.
Positive screenings undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. Required presumptive positive samples are cleansed prior to Confirmation. From Accessioning to Confirmation, the entire process is regulated by CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 credential standards.
