The utilization of hair testing has emerged as a formidable method for identifying drug and alcohol consumption. Hair strands capture biomolecular evidence within their fibers, providing an extended timeline of substance usage. When acquired in close proximity to the scalp, hair samples can present nearly a three-month detection period for drugs and alcohol. Collecting hair is straightforward, challenging to tamper with, and convenient to transport.
Obtaining a 1.5-inch hair sample consisting of approximately 200 strands nearest to the scalp yields 100mg of hair, the optimal quantity for testing and confirmation processes. For EtG or additional tests exceeding 10 panels, a sample weighing 150mg is advised. Utilizing a jeweler’s scale for precise measurement is suggested. If scalp hair cannot be obtained, an equivalent volume of body hair is acceptable. References to head hair imply scalp hair, while body hair encompasses all other types (such as facial and axillary hair).
Process Overview
The laboratory procedure for evaluating a drug test result encompasses four fundamental stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially integrated into a laboratory's system, entailing validation of proper sealing and shipping, allocation of a unique LAN (Laboratory Accessioning Number), and completion of any data entry not facilitated by an electronic chain of custody system.
The Screening phase involves a preliminary assessment for the presence of drugs. This step is a cost-efficient means to exclude drug use in the majority of samples; however, a positive screening necessitates confirmation for court admissibility. Samples yielding presumptive positive results require additional confirmation testing.
In cases of presumptive positivity at the Screening stage, further hair is extracted from the original sample for the Extraction phase, where drugs are isolated at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug screening.
Positive screening results are substantiated through GC/MS, GC/MS/MS, or LC/MS/MS confirmation techniques. All presumptive positive specimens undergo washing prior to confirmation as required. The comprehensive laboratory workflow, from Accessioning to Confirmation, is evaluated in accordance with both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation criteria.
Advantages of hair drug testing:
Limitations:
Note: Although commonly termed "hair follicle tests," the actual analysis is conducted on the hair strands rather than the follicles beneath the scalp.
