Hair analysis is now recognized as an effective means for identifying drug and alcohol consumption. It offers a long-term profile by capturing biomarkers within the strands of hair as they grow. Hair, when collected near the scalp, can reflect a detection period of up to around 3 months for substances. It is straightforward to collect, hard to tamper with, and simple to transport.
A 1.5-inch section comprising roughly 200 strands (equivalent to a #2 pencil's diameter) next to the scalp should yield 100mg, which is the ideal sample for initial tests and validations. For EtG, added tests, and panels exceeding 10, a sample of 150mg is advisable. We suggest using a jeweler’s scale for accurate measurement. If scalp hair isn't available, a similar quantity of body hair can be used. When “head hair” is mentioned, it specifically means scalp hair, while “body hair” includes other types such as facial or axillary hair.
Process Overview
There are four main stages in processing drug test results in a lab: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step, where a sample is logged into the lab’s system. This step verifies the integrity of the sample's packaging and shipping, assigns it a unique LAN (Laboratory Accessioning Number), and enters any further required information not part of an electronic chain of custody.
Screening is a preliminary and swift assessment for drug traces. It’s economically efficient for excluding drug presence in most samples. Nevertheless, positive results from this stage must be verified to be used legally. Samples that test possibly positive during Screening require further validation.
For samples showing potential positivity during Screening, additional hair is retrieved from the initial collection for Extraction. At this stage, substances are extracted from hair at concentrations lower than some other methods (like urine or saliva), contributing to the complexity of hair testing.
Verification of positive screening outcomes employs GC/MS, GC/MS/MS, or LC/MS/MS methods. Samples marked positive are prepped through washing as needed for verification. The processes from Accessioning to Confirmation are conducted under the supervision of both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
