Hair examinations are increasingly valued for identifying substance and alcohol consumption. Hair encases a prolonged timeline of alcohol and drug use by embedding markers within the fibers of the hair as it grows. When gathered near the scalp, it can yield a detection period of up to roughly three months for substances. Hair is straightforward to gather, relatively resistant to tampering, and simple to transport.
A 1.5-inch section of roughly 200 hair strands (comparable to a #2 pencil in diameter) nearest the scalp provides 100mg of hair, which is optimal for analysis and corroboration. For EtG, supplementary tests, and/or inquiries exceeding ten panels, a specimen of 150mg is advisable. We propose using a jeweler's scale to ascertain the specimen's mass. If collecting from the scalp is unattainable, a similar volume of body hair may be used. When mentioning head hair, we imply scalp hair solely. Body hair encompasses all other types (beard, underarm, etc.).
Process Overview
The key phases in a laboratory's drug test processing include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preliminary sample integration into the lab's system. This step ensures the sample was properly sealed and dispatched, assigns a unique LAN (Laboratory Accessioning Number), and fulfills any extra data entry not established by an electronic chain-of-custody framework.
Screening signifies an expedited preliminary check for illicit substances. Although Screening economically rules out drug presence in most cases, any positive findings necessitate validation to be permissible in legal settings. Samples considered presumptively positive in Screening must undergo additional confirmation.
Should a sample exhibit presumptive positivity in the Screening phase, additional hair is procured from the originating sample for Extraction. This phase extracts substances from hair at significantly lower concentrations compared to other modes (e.g., urine or saliva), underscoring the complexity of hair-specific drug analyses.
Confirmation of any Screening-positives employs GC/MS, GC/MS/MS, or LC/MS/MS. All samples considered presumptive positives are cleansed before verification as warranted. The comprehensive lab cycle from Accessioning to Confirmation adheres to both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
