Urine| Hair Follicle | Oral Fluid | Blood | ETG
Hair analysis has emerged as an influential method for identifying use of narcotics and alcohol. Hair offers an extended historical record of substance ingestion by embedding markers within the fibers of the growing hair shaft. When obtained close to the scalp, this method can reveal up to an approximate 3-month detection period for substances. It is straightforward to gather hair, challenging to forge, and simply shipped.
A section of hair measuring 1.5 inches with approximately 200 hairs (akin to the thickness of a #2 pencil) near the scalp will yield 100mg, ideal for analysis. For EtG, supplementary checks, and/or examinations exceeding 10 panels, 150mg of the sample is advised. It's suggested to measure the sample with a jeweler’s scale. If scalp hair is not accessible, an equivalent amount of body hair can be used. "Head hair" exclusively pertains to scalp hair, whereas "body hair" encompasses other varieties (facial, axillary, etc.).
Procedure Summary
Laboratory processing of a drug test encompasses four principal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where a sample is processed within a laboratory's framework, ensuring the sample was properly sealed and transported, assigning an arbitrary LAN (Laboratory Accessioning Number), and performing any necessary manual data submission absent in an electronic custody chain system.
Screening involves an initial rapid evaluation for controlled substances, offering a cost-efficient approach to dismiss drug use in most samples. However, a screening positive result must undergo confirmation to be legally defensible. Any presumptive positives identified in Screening necessitate further verification.
Upon a presumptive positive in the Screening stage, additional hair is extracted from the original sample for Extraction. Here, narcotics are pulled from hair at a reduced concentration compared to other methodologies (e.g., urine or oral fluid), contributing to the complexity of hair drug screening.
Confirmation of any presumptive positive result is handled through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo necessary cleansing pre-confirmation. The entire lab sequence from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
