The examination of hair is increasingly recognized as an effective means for identifying the use of drugs and alcohol. Hair retains a prolonged history of substances as it encases biomarkers within the strands of actively growing hair. When procured from near the scalp, hair can offer an approximate detection period of three months for alcohol and other substances. Collecting hair is straightforward, challenging to tamper with, and effortless to transport.
A hair sample measuring 1.5 inches, consisting of roughly 200 strands (similar in size to a #2 pencil) located closest to the scalp, yields 100mg of hair, which is the optimal quantity for analysis and confirmation. For tests like EtG add-ons and those exceeding 10 panels, a specimen of 150mg is advised. It is suggested to measure the specimen using a jeweler’s scale. In instances where scalp hair is inaccessible, an equivalent volume of body hair might be utilized. “Head hair†exclusively refers to scalp hair, whereas “body hair†encompasses all other types (such as facial, axillary, etc.).
Process Overview
The quartet of primary phases in laboratory processing for drug test outcomes includes Accessioning, Screening, Extraction, and Confirmation.
Accessioning is concerned with the initial integration of a sample into a laboratory’s framework. This step involves ensuring the sample was properly sealed and dispatched, allocating a LAN (Laboratory Accessioning Number), and concluding any supplementary data entry absent from an electronic chain of custody system.
Screening entails a preliminary assessment for illicit substance use. Although Screening presents an economical means to disregard drug consumption in the majority of cases, a positive detection requires validation for court admissibility. Samples that yield presumptive positives in the Screening stage necessitate a secondary confirmation.
When a sample indicates a presumptive positive during Screening, additional hair from the original sample is retrieved and readied for Extraction. In this phase, hair undergoes drug extraction at significantly lower concentrations than other methods (such as urine or oral fluid), underscoring why hair drug screening presents the most complex methodology.
Confirmation of any initial positive findings undergoes analysis using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation as necessary. The complete laboratory procedure from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair specification and adheres to accreditation by ISO / IEC 17025 standards.
