Hair analysis has emerged as a robust method for identifying alcohol and drug consumption. Hair captures a prolonged timeline of substance use, preserving biomarkers within the strands as they grow. When acquired near the scalp, hair offers a detection period of up to approximately three months for alcohol and drugs. Its collection is straightforward, relatively resistant to tampering, and convenient for transport.
An ideal sample consists of a 1.5-inch section of about 200 hairs (comparable to a #2 pencil in thickness) nearest to the scalp, yielding 100mg—perfect for both screening and confirmation. For EtG or extended tests exceeding 10 panels, 150mg is preferred. It's advisable to verify the specimen's weight using a jeweler's scale. If scalp hair isn't accessible, a similar quantity of body hair may be taken. The term head hair specifically refers to scalp hair, while body hair encompasses all other types (such as facial or axillary).
Process Overview
The laboratory methodology for analyzing a drug test result encompasses four principal stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning initiates with incorporating a specimen into the laboratory's system. This step confirms the sample's secure sealing and proper shipment, assigns a random LAN (Laboratory Accessioning Number), and completes additional data entry omitted by an electronic chain of custody.
Screening offers an initial, rapid evaluation for substances of misuse. Though cost-effective and useful for ruling out drug use in most specimens, positive results from Screening must be validated for legal acceptance, necessitating secondary confirmation.
If Screening indicates a presumptive positive, additional hair is extracted from the original sample and readied for Extraction. At this stage, drugs are separated from hair at much lower concentrations than other methods (e.g., urine or oral fluids), contributing to the complexity of hair drug analysis.
Confirmation of positive screenings is performed through GC/MS, GC/MS/MS, or LC/MS/MS methods. All presumptive positives undergo washing before confirmation as required. The complete lab process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair program and accreditation to ISO/IEC 17025 standards.
