Hair analysis has emerged as an effective means for detecting drug and alcohol consumption. Hair captures long-term traces of alcohol and other substances by retaining biomarkers within the strands of hair as they grow. When hair samples are taken near the scalp, they offer a detection period of up to about three months for alcohol and other substances. Collecting hair samples is straightforward, challenging to tamper with, and convenient to transport.
A 1.5-inch section containing roughly 200 hair strands (approximately the width of a #2 pencil) nearest to the scalp yields 100mg, which is the ideal sample size for both testing and validation. For EtG, additional tests, or panels exceeding 10, a specimen weighing 150mg is preferred. Utilizing a jeweler's scale to measure the specimen is suggested. Should scalp hair be unavailable, a similar weight of body hair can be obtained. When mentioning head hair, it specifically signifies scalp hair alone. Body hair encompasses all other hair (facial, axillary, etc.).
Process Overview
The four essential stages in processing drug tests in the laboratory are Accessioning, Screening, Extraction, and Confirmation.
Accessioning constitutes the initial handling of a sample for entry into a laboratory system. This step includes checking that the sample is correctly sealed and dispatched, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any additional information entry not covered by an electronic chain of custody protocol.
Screening concerns an initial swift evaluation for substances of abuse. Although Screening is an economical approach to exclude drug use in most samples, a favorable screen outcome must be followed by a confirmation to be court-acceptable. Samples exhibiting a presumptive positive in Screening will necessitate further validation.
When a Screening indicates a presumptive positive result, extra hair from the original sample is prepared for Extraction. During this phase, drugs are drawn from hair in much smaller concentrations than with other methods (e.g., urine or oral fluids), marking hair drug testing as the most complex methodology.
Validation of any positive Screening outcome is pursued using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Before verification, all presumptive positive samples undergo necessary cleansing. From Accessioning through to Confirmation, the entire lab procedure is conducted in conformity with the CAP (College of American Pathologists) Hair classification and adherence to ISO / IEC 17025 standards.
