Acknowledged as an effective method, hair testing has emerged as an invaluable asset for spotting drug and alcohol consumption. Hair captures a prolonged history of substances by embedding biomarkers in the hair's developing strands. When hair is taken close to the scalp, it can offer an approximate three-month detection period for substances. Its simple collection process, difficulty in tampering, and ease of shipment are notable features.
A sample of 1.5 inches containing about 200 strands (roughly the width of a #2 pencil) near the scalp yields 100mg of hair, which is optimal for both screening and confirmation stages. For EtG, add-ons, and tests beyond 10 panels, a sample weighing 150mg is advised. Utilizing a jeweler’s scale to weigh the specimen is suggested. Should scalp hair be unobtainable, an equivalent amount of body hair is acceptable. References to "head hair" specify scalp hair, whereas "body hair" includes all other types (facial, axillary, etc).
Process Overview
The laboratory operations for processing drug test results comprise four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample in the laboratory framework. This process confirms appropriate sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and finalizes any remaining data entry absent from the electronic chain of custody system.
Screening performs a preliminary, swift assessment for substances of abuse. Though Screening serves as a budget-friendly means to exclude drug use across most samples, confirmatory testing is required for legal admissibility. Any samples testing provisionally positive in Screening need further verification.
Upon a provisional positive result during Screening, additional hair is extracted from the initial sample for the Extraction phase. Here, drugs are isolated from hair at lower concentrations compared to other tests (like urine or oral fluid), highlighting the complexity of hair drug screening.
Confirmation of any positive Screening output is executed using GC/MS, GC/MS/MS, or LC/MS/MS methods. Any samples presumed positive undergo washing as part of confirmation, if necessary. This entire laboratory procedure from Accessioning to Confirmation undergoes evaluation under the CAP (College of American Pathologists) Hair standard and aligns with ISO/IEC 17025 accreditation.
