Hair analysis is highly regarded for its efficacy in detecting drug and alcohol consumption. Hair strands capture long-term histories of these substances by embedding biomarkers within their fibers as they grow. A collection near the scalp offers a detection period of around 3 months for alcohol and drugs. Sampling hair is straightforward, tampering is challenging, and transportation is easy.
Collecting a sample of 1.5 inches, totaling about 200 hair strands (approximately the diameter of a #2 pencil), provides 100mg of hair, which is the perfect sample size for assessment. For EtG, additional tests, and/or more than 10 panels, 150mg is advisable. Using a jeweler’s scale for measurement is suggested. If scalp hair is not present, an equivalent quantity of body hair is acceptable. "Head hair" specifically refers to scalp hair, whereas "body hair" encompasses all other types like facial or axillary hair, etc.
Process Overview
Analyzing a drug test sample in a lab involves these major stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial handling of a sample into a lab’s workflow. This step ensures the sample is properly sealed and shipped, assigns it a random LAN (Laboratory Accessioning Number), and includes any remaining data tasks not automatically managed by an electronic custody system.
Screening performs a preliminary assessment for abusive substances. This method serves as a cost-effective preliminary check for the majority of samples to clear drug presence, but any positive findings from this step need corroboration to be valid in a legal context. Samples with potential positive results in Screening must also go through a further confirmation process.
Should a sample yield a potential positive during Screening, additional hair is taken from the original collection for Extraction. In this stage, substances are extracted from hair at notably lower concentrations compared to other methodologies like urine or saliva, which makes hair drug analysis more complex to conduct.
Substantiation of any positive results from Screening is executed through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples undergo cleaning before confirmation as necessary. The complete lab process, from Accessioning to Confirmation, aligns with CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
