Hair testing is increasingly recognized as an effective method for uncovering drug and alcohol consumption. Hair records a prolonged history of alcohol and drug exposure by encasing biomarkers in the fibers as the hair grows. When taken near the scalp, hair can reflect up to a three-month history of drug and alcohol use. Hair collection is straightforward, challenging to tamper with, and simple to send.
A sample measuring 1.5 inches, consisting of roughly 200 hairs (comparable to the thickness of a #2 pencil), close to the scalp is ideal, yielding 100mg of hair, perfect for tests. For EtG additionals, or analyses exceeding 10 panel tests, 150mg of the hair is suggested. It is advisable to weigh the sample using a jeweler’s scale. If scalp hair isn't available, an equivalent portion of body hair may be gathered. References to head hair pertain exclusively to scalp hair. Body hair includes all other hair types, such as facial and axillary hair.
Process Overview
The laboratory processing of a drug test result consists of four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step where a sample is integrated into a laboratory's system. This step involves ensuring the sample is correctly sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and logging in any additional information not furnished by an electronic chain of custody system.
Screening is a preliminary evaluation for drug substances. While it's an affordable approach to exclude drug use for most specimens, a positive finding needs confirmation for it to be court-acceptable. Any samples that exhibit positive results during Screening require further verification.
For samples that indicate positive results in Screening, additional hair is extracted from the primary sample to proceed to Extraction. This phase involves extracting drugs from hair at significantly lower concentrations compared to other methods (like urine or oral fluid), which makes hair drug screening a challenging procedure.
Confirmation of any positive screening is done using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleaned before confirmation, as needed. The entire lab process from Accessioning through Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and the accreditation standards of ISO / IEC 17025.
