Hair analysis has gained recognition as an effective method for identifying drug and alcohol consumption. Hair captures a comprehensive record of alcohol and drug presence by embedding biomarkers within the strands as they grow. When harvested near the scalp, hair offers a detection period of up to roughly three months for alcohol and drugs. The collection process is straightforward, tampering is challenging, and it is easy to transport.
A 1.5-inch segment consisting of approximately 200 hair strands (comparable to the thickness of a #2 pencil) positioned nearest to the scalp yields 100mg of hair, which is the quintessential amount for both screening and confirmation. For EtG, additional tests, or panels exceeding 10, 150mg of the sample is advisable. We suggest measuring the sample using a jeweler's scale. If scalp hair is not obtainable, an equivalent quantity of body hair might be used. Specifically, 'head hair' refers solely to scalp hair, while 'body hair' encompasses all other types (such as facial, axillary, etc.).
Process Outline
The laboratory processing of drug test results encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step where a sample is integrated into a laboratory's system. This stage ensures the sample was adequately sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and finalizes any remaining data entry absent from an electronic chain of custody.
Screening entails an initial rapid assessment for drug abuse. While Screening efficiently eliminates drug usage in most samples, any positive findings need to be verified for legal admissibility. Samples deemed presumptively positive in Screening require confirmatory testing.
Should a sample be judged as positive in Screening, additional hair is extracted from the original sample for the Extraction process. This stage involves extracting drugs from hair at considerably lower concentrations compared to other methods (like urine or oral fluids), establishing hair drug testing as a challenging technique.
Confirmation for any Screening-positive results occurs through GC/MS, GC/MS/MS, or LC/MS/MS technologies. Presumptive positive samples undergo washing before confirmation as necessary. The complete laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
