Hair testing is now viewed as a robust method for detecting drug and alcohol consumption. Hair captures a comprehensive record of alcohol and drug exposure by embedding biomarkers within its fibers during growth. When taken near the scalp, hair can reveal drug and alcohol usage over a window of roughly three months. The collection of hair is straightforward, relatively resistant to tampering, and easy to transport.
A sample of 1.5 inches consisting of about 200 hair strands (comparable in size to a #2 pencil) proximal to the scalp yields 100mg, which is the optimal amount for both screening and confirmation. For advanced testing like EtG, add-on panels, or tests beyond 10 panels, a sample of 150mg is preferred. It's advised to measure the sample using a jeweler’s scale. In instances where scalp hair isn’t available, a similar quantity of body hair can be used. "Head hair" specifically refers to scalp hair. Conversely, "body hair" encompasses all other types such as facial and axillary hair.
Process Overview
The process of laboratory drug test analysis includes four major stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into the laboratory’s workflow. This step entails confirming the sample’s proper sealing and shipment, generating a random LAN (Laboratory Accessioning Number), and entering any data not supplied by an electronic chain of custody system.
Screening is an initial rapid evaluation for drug presence. While screening is an economical method to dismiss drug use in most samples, any positive results necessitate a confirmation for legal acceptability. Samples flagged as presumptively positive in Screening must undergo further confirmation.
When a sample shows a presumptive positive during Screening, additional hair will be prepared from the initial sample for Extraction. At this stage, drugs are extracted from hair at significantly lower concentrations compared to other methods (such as urine or oral fluids), which makes hair drug screening particularly challenging.
Positive results in the Screening phase are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS methodologies. Prior to confirmation, presumptive positive samples are cleaned as required. From the Accessioning to Confirmation stages, the entire laboratory procedure is scrutinized under CAP (College of American Pathologists) Hair standards as well as ISO/IEC 17025 accreditation.
