Hair analysis is recognized as an effective means for identifying drug and alcohol consumption. Hair serves as a chronicled record of alcohol and drug usage by encapsulating biomarkers within the fibers of the growing strand. When collected adjacent to the scalp, it offers a detection span of up to roughly three months for alcohol and drugs. The collection process is straightforward, tampering is rather challenging, and shipping is uncomplicated.
A 1.5-inch cut of about 200 hair strands (similar to the girth of a #2 pencil) adjoining the scalp yields 100mg of hair, which is optimal for screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, a sample weighing 150mg is advised. We suggest using a jeweler’s scale for precise measurement. If scalp hair cannot be acquired, an equivalent quantity of body hair is an appropriate substitute. When addressing head hair, we refer exclusively to scalp hair. The term body hair encompasses facial hair, axillary hair, and other types.
Process Overview
The laboratory processing of drug test outcomes involves four critical steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial sample handling within a lab’s framework. This process encompasses verifying the sample’s proper sealing and shipping, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any residual data entry absent from an electronic chain of custody system.
Screening is a preliminary evaluation for the presence of drugs. Although Screening is an economical method to exclude drug usage for most samples, any positive findings must be validated to be legally admissible. Samples that present presumptively positive in Screening necessitate a secondary confirmation.
If a specimen shows presumptive positivity during Screening, additional hair is extracted from the original sample for the Extraction process. Here, substances are drawn from the hair at notably lower concentrations compared to alternate methodologies, such as urine or oral fluid testing, establishing hair drug analysis as the most complex methodology to execute.
Authentication of any positive Screening result is pursued via GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptively positive undergo washing before confirmation as required. The full laboratory sequence from Accessioning to Confirmation is evaluated under the dual criteria of the CAP (College of American Pathologists) Hair classification and compliance with ISO/IEC 17025 standards.
