Hair analysis is increasingly recognized as a potent method for identifying drug and alcohol usage. Hair offers a comprehensive record of alcohol and other substance use by capturing biomarkers within the hair strand fibers. Collected near the scalp, hair can suggest a detection window of up to three months for alcohol and other substances. Hair collection is uncomplicated, moderately resistant to tampering, and easily transported.
A sample measuring 1.5 inches, consisting of around 200 hair strands (approximately the thickness of a #2 pencil) close to the scalp culminates in 100mg of hair, the optimal amount for both initial screening and confirmation. For EtG, additional tests, or tests exceeding ten panels, a 150mg specimen is advised. Using a jeweler's scale for specimen weighing is suggested. Should scalp hair be unobtainable, an equivalent quantity of body hair may be gathered. References to head hair intend scalp hair exclusively; body hair encompasses all other types (e.g., facial, axillary).
Process Overview
Four principal stages constitute the lab processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary integration of a sample into a lab’s system. This process includes ensuring proper sealing and shipment of the sample, generating a random LAN (Laboratory Accessioning Number), and completing any required data entry absent from an electronic chain of custody system.
Screening is a preliminary evaluation for drugs of misuse. Though a cost-efficient means to dismiss drug usage on most samples, Screening positives require confirmation for court acceptance. Samples testing presumptively positive in Screening mandate a further confirmation.
Should a sample appear presumptively positive during Screening, additional hair is retrieved from the initial specimen for Extraction. Here, drugs are isolated from hair at notably reduced concentrations compared to other methods (e.g., urine or oral fluids), underscoring why hair drug screening remains the utmost challenging methodology.
Confirmed positive screening results undergo verification through GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, washing of all presumptive positive samples occurs as warranted. The full lab process from Accessioning to Confirmation undergoes evaluation under the CAP (College of American Pathologists) Hair classification and with ISO/IEC 17025 standards accreditation.
