The use of hair testing has gained recognition as an effective method for identifying drug and alcohol consumption. Hair captures a comprehensive record of substance intake by encasing biomarkers within its fibrous structure. When clipped near the scalp, hair offers roughly a 3-month timeframe to detect drugs and alcohol. Collecting hair is straightforward, somewhat resistant to tampering, and convenient to transport.
A sample measuring 1.5 inches and comprising roughly 200 hair strands (similar in size to a #2 pencil) nearest the scalp yields 100mg, an ideal quantity for initial testing and verification. For tests involving EtG, additional factors, and/or beyond 10 panels, a collection of 150mg is advised. We suggest using a jeweler’s scale for precise measurement. If scalp hair is unavailable, an equivalent volume of body hair can be substituted. When referencing head hair, we specifically mean scalp hair, while body hair encompasses all other forms (facial, underarm, etc.).
Process Overview
The laboratory procedure for determining a drug test outcome comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the sample’s initial entry into the laboratory system. It ensures the sample’s seal and shipment integrity, assigns a random LAN (Laboratory Accessioning Number), and finalizes any missing details not captured by an electronic tracking system.
Screening entails a preliminary swift assessment for drug presence. It serves as a cost-efficient method to dismiss drug use across most samples; however, for legal validation, a positive finding must undergo confirmation. Samples preliminarily identified as positive in Screening require an additional verification procedure.
When a sample preliminarily tests positive during Screening, additional hair from the initial collection is isolated for the Extraction phase. In this phase, drugs are drawn from hair at significantly lower concentrations than found in alternative methods (such as urine or oral fluid), underscoring the complexity of hair drug analysis.
To confirm any positive screening results, techniques like GC/MS, GC/MS/MS, or LC/MS/MS are employed. All samples with a presumptive positive outcome are cleaned before the confirmation stage if necessary. The entire laboratory procedure, spanning Accessioning to Confirmation, is thoroughly scrutinized under the CAP (College of American Pathologists) Hair guidelines and meets the ISO / IEC 17025 accreditation requirements.
