Hair analysis is now regarded as an effective approach for identifying substance use. Hair strands offer a prolonged record of such usage by capturing biomarkers within the developing hair shaft. When procured near the scalp, these strands can offer nearly a 3-month window of detectability for drugs and alcohol. The collection process is straightforward, tampering is relatively challenging, and shipping is convenient.
A sample length of 1.5 inches, comprising roughly 200 hairs (around the girth of a #2 pencil) near the scalp, yields 100mg, which is the optimal amount for testing and verification. For EtG, supplemental analyses, and assessments over 10 panels, 150mg of the sample is advised. Utilizing a jeweler's scale to weigh the sample is recommended. If scalp hair is not available, a proportional amount of body hair may be used. References to head hair denote only scalp hair. Body hair covers all other types such as facial or axillary hair.
Process Overview
The comprehensive workflow in a laboratory setting for generating a drug test report encompasses Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves incorporating the sample into the lab's system. Tasks include verifying correct sealing and shipping of the sample, allocating a unique LAN (Laboratory Accessioning Number), and completing any necessary manual data entries absent in an electronic custody protocol.
Screening performs a preliminary analysis for drug misuse. It serves as a budget-friendly method to exclude drug presence in the majority of samples, though a positive indication necessitates further verification to be valid in legal settings. Presumptive positive outcomes in Screening require further corroboration.
Upon receiving a presumptive positive in Screening, additional hair is extracted from the original sample and prepped for the Extraction phase. Drugs are isolated from hair at notably lower concentrations than other tests (like urine or oral fluids), making hair drug screening quite challenging to execute.
Confirmation of any positive result from Screening is done through GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positives are washed as needed. The full laboratory process from Accessioning to Confirmation is scrutinized under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
