Hair examination is now regarded as an effective means for identifying drug and alcohol consumption. Hair offers an extended timeline of alcohol and drug usage by capturing biomarkers within the strands as they grow. When cut close to the head, hair can reveal up to roughly a 3-month period of drug and alcohol presence. Hair is uncomplicated to gather, relatively resistant to tampering, and straightforward to mail.
A sample of hair measuring 1.5 inches, comprising approximately 200 strands (equivalent to a #2 pencil), near the scalp provides 100mg, which is the optimal amount for assessment and validation. For EtG, supplementary tests, and tests exceeding 10 panels, 150mg of hair is advised. We suggest weighing the hair on a jeweler’s scale. If head hair isn't available, a comparable amount of body hair might be used. When discussing head hair, we specifically mean scalp hair. Body hair includes all other hair (facial, axillary, etc.).
Process Overview
The laboratory workflow for analyzing a drug test result involves four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase of introducing a sample into a laboratory’s system. This encompasses verifying that the sample was correctly sealed and dispatched, allocating a unique LAN (Laboratory Accessioning Number), and completing any extra data entry lacking from an electronic chain of custody.
Screening is a preliminary analysis for drugs known to be abused. Though it's a cost-efficient approach to dismiss drug usage for most samples, a positive result requires validation for legal acceptability. Any samples flagged as presumptively positive during Screening must undergo a secondary verification.
In cases where a sample shows presumptive positivity during Screening, additional hair is extracted from the initial specimen for the Extraction phase. This stage involves extracting drugs from hair at lower concentrations compared to other techniques (e.g., urine or saliva), highlighting the complexity of hair drug testing.
Confirmation for any positive screening outcome is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are washed before confirmation as deemed necessary. The entire laboratory process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation.
