Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair strands hold a prolonged record of substance usage by capturing biomarkers within their fibers. If cut close to the scalp, hair can reveal drug or alcohol use over roughly a 3-month timeframe. Hair is easy to collect, hard to tamper with, and simple to send.
A 1.5-inch section containing about 200 hair strands (similar in size to a #2 pencil) taken from the scalp will yield 100mg of hair, which is the optimal amount for testing and confirmation. For EtG, additional tests, or those exceeding 10 panels, 150mg is suggested. It's advisable to weigh the hair with a jeweler's scale. If scalp hair isn't accessible, a similar quantity of body hair can be obtained. References to head hair imply only scalp hair, while body hair includes all other types (like facial or axillary).
Process Overview
The laboratory analysis of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of initially integrating a sample into a laboratory’s system. This step ensures the sample's seal and shipment are intact, assigns a random Laboratory Accessioning Number (LAN), and fulfills any data entry not provided by an electronic chain of custody system.
Screening is a preliminary assessment for drugs. Though it is a cost-efficient means to exclude drug use from most samples, a positive screening outcome requires confirmation to be valid in legal settings. Any samples that appear positive during Screening necessitate a further confirmatory test.
For samples indicated as positive during Screening, additional hair is taken from the original sample for Extraction. This phase involves extracting drugs from hair at concentrations far lower than other methods (such as urine or oral fluid), making hair drug testing a challenging procedure.
Confirmation of any positive screen utilizes GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptively positive samples are cleansed before confirmation if needed. The complete laboratory process from Accessioning through Confirmation is scrutinized under CAP (College of American Pathologists) Hair designation alongside ISO / IEC 17025 standards accreditation.
