Hair testing is recognized as a robust instrument for identifying drug and alcohol consumption. Hair captures long-term biomarker histories of alcohol and drugs within the fibers of the maturing hair strand. When obtained close to the scalp, hair can deliver up to an estimated 3-month detection timespan for alcohol and substances. Hair sample collection is straightforward, challenging to alter, and convenient to transport.
A 1.5-inch piece, comprising roughly 200 hair strands (comparable to the girth of a #2 pencil) nearest to the scalp will provide 100mg of hair, which is the perfect sample size for screening and verification. For EtG, add-ons, and/or tests surpassing 10 panels, 150mg of the sample is advised. We suggest utilizing a jeweler’s scale to weigh the specimen. In cases where scalp hair is absent, an equivalent quantity of body hair may be taken. In terms of head hair, it pertains solely to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test outcome encompasses four principal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step of integrating a sample into the lab’s framework. This includes confirming the sample was sealed and dispatched correctly, assigning a random LAN (Laboratory Accessioning Number), and accomplishing any supplemental data input absent in an electronic chain of custody protocol.
Screening encompasses an initial brisk review for substances of concern. While Screening offers a cost-effective manner to discount drug usage across the majority of samples, it requires a validated confirmation for court admissibility. Samples showing presumptive positivity in Screening necessitate a subsequent confirmation.
Samples registering presumptive positivity within Screening proceed with further hair extraction from the original sample and preparation for Extraction. During this phase, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), highlighting why hair drug screening is the most intricate methodology available.
Any outcome showing positivity is confirmed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positivity undergo washing before confirmation where necessary. The complete laboratory workflow, from Accessioning through to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair categorization alongside ISO / IEC 17025 accreditation standards.
