Hair analysis has evolved into an effective resource for identifying substance and alcohol consumption. Hair offers an extended timeline of alcohol and drug presence by capturing biomarkers within the fibers of the evolving hair strand. When retrieved close to the scalp, it can offer an approximate three-month window of detection for substances. It is straightforward to gather, somewhat resistant to tampering, and simple to transport.
A 1.5-inch segment of roughly 200 hair strands (comparable to a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal amount for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, 150mg of hair is advised. It is recommended to weigh the specimen using a jeweler’s scale. If scalp hair cannot be obtained, a corresponding amount of body hair is acceptable. When mentioning head hair, it pertains to scalp hair exclusively. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The four essential stages in the laboratory assessment of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial processing of a specimen into the laboratory’s framework. This entails verifying that the specimen was correctly sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain of custody system.
Screening constitutes a preliminary rapid assessment for substances of misuse. While Screening is an economical approach to rule out narcotic usage for the majority of specimens, any positive finding must be confirmed for court admissibility. Specimens that yield a presumptive positive during Screening necessitate a secondary confirmation.
If a specimen indicates a presumptive positive during the Screening phase, more material is drawn from the original sample and readied for Extraction. At this phase, substances are extracted from hair in significantly lower concentrations than through other methods (e.g., urine or oral fluid), underscoring why hair analysis poses the most challenging methodology.
Confirmation of any positive Screening outcome is accomplished via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens undergo a washing process prior to confirmation as required. The entire laboratory procedure from Accessioning to Confirmation is inspected under both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.
