Hair analysis is now recognized as a robust method for identifying drug and alcohol consumption. Hair offers a comprehensive timeline of drug and alcohol use by embedding biomarkers within the growing hair strand. When taken near the scalp, hair can reveal drug use history for up to about three months. The collection is straightforward, tampering chances are low, and shipping is uncomplicated.
A 1.5-inch segment comprising roughly 200 hair strands (equivalent to a #2 pencil) near the scalp yields about 100mg, which is optimal for both screening and confirmation. For EtG assays, additional testing, and/or panels beyond 10, a 150mg specimen is advisable. Using a jeweler’s scale to weigh the sample is suggested. If scalp hair cannot be collected, an equal amount of body hair is an alternative. In this context, head hair specifically pertains to scalp hair, while body hair includes all other types (facial, axillary, etc.).
Process Overview
The sequence involved in laboratory processing of a drug test result includes four principal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the preliminary processing phase of incorporating a sample into a lab’s system. This step involves ensuring proper sealing and shipment of the sample, assigning it a random LAN (Laboratory Accessioning Number), and complementing any missing data not covered by an electronic chain of custody system.
Screening serves as an initial rapid assessment for substance misuse. Although Screening is an effective means to eliminate drug usage in most samples, a positive result from the screening stage necessitates confirmation for legal admissibility. All presumptively positive screenings require an additional confirmation.
Should a sample register a presumptive positive in the Screening phase, further hair is extracted from the original specimen for Extraction. During this operation, drugs are isolated from hair at significantly lower concentrations than in other approaches (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.
The Confirmation phase for any positive screening results is executed via GC/MS, GC/MS/MS, or LC/MS/MS methods. Prior to confirmation, all presumptive positive samples undergo cleaning as needed. The entirety of the lab process from Accessioning through Confirmation undergoes scrutiny under the CAP (College of American Pathologists) Hair designation in line with the accreditation to ISO / IEC 17025 standards.
