Hair analysis is regarded as an effective method for identifying drug and alcohol consumption. Hair retains a long-term record of substances by capturing indicators within the fibers of the growing strands. When obtained near the scalp, hair can present a detection period of up to roughly 3 months for these substances. Gathering hair is straightforward, fairly tamper-resistant, and convenient to transport.
A sample measuring 1.5 inches of approximately 200 hair strands (comparable to the diameter of a #2 pencil) nearest the scalp should yield 100mg of hair, an optimal amount for both screening and subsequent verification. For EtG, additional analyses, and/or tests exceeding 10 panels, 150mg of the specimen is advised. It's best to use a jeweler’s scale to weigh the sample. If scalp hair isn’t accessible, an equivalent amount of body hair can be obtained. By head hair, we mean scalp hair alone. Body hair indicates any other types (facial, axillary, etc.).
Process Overview
The core steps in laboratory drug testing are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into the lab's system. This phase ensures the sample was sealed and shipped correctly, assigns a random LAN (Laboratory Accessioning Number), and finalizes any extra data input absent in an electronic chain of custody system.
Screening is a preliminary assessment for drug presence. While it’s a cost-effective way to rule out drug usage in the majority, a positive screen must be confirmed for legal admissibility. Tests indicating a potential positive result during Screening need retesting for validation.
Should a sample show a probable positive result in Screening, additional hair is extracted from the original sample for Extraction. At this stage, drugs are extracted from hair at significantly lower concentrations than other methodologies (e.g., urine or oral fluid), explaining why hair drug analysis is among the most intricate techniques to apply.
Substantiation of any positive screen result is carried out via GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are cleansed prior to confirmation if necessary. Each phase from Accessioning through Confirmation undergoes a review under both the CAP (College of American Pathologists) Hair guidelines and accreditation to ISO / IEC 17025 standards.
