Hair analysis is recognized as an effective means for identifying drug and alcohol use. It captures a long-term record of alcohol and drug intake by embedding markers within the structure of the hair as it grows. When taken from near the scalp, hair can offer a detection period of up to three months for alcohol and drugs. Collection is straightforward, tampering is challenging, and shipping is convenient.
A sample measuring 1.5 inches of around 200 hair strands (roughly the diameter of a #2 pencil) closest to the scalp provides 100mg, which is optimal for both screening and confirmation. For EtG, add-ons, or tests that exceed 10 panels, 150mg is advisable. It's best to weigh the sample using a jeweler’s scale. If scalp hair isn't accessible, an equivalent quantity of body hair is an alternative. By head hair, we mean scalp hair specifically. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The key stages in laboratory drug test processing include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage where a sample is entered into a lab’s framework. This step ensures the sample's seal and shipment integrity, assigns a unique LAN (Laboratory Accessioning Number), and completes any extra data input not covered by an electronic chain of custody.
Screening provides an initial, quick evaluation for substance abuse. Although it is an economical method to exclude drug use in most samples, a positive screen must be verified to be legally admissible. Any samples that return a presumptive positive result in Screening need a confirmatory test.
Should a sample be presumptively positive during Screening, additional hair is extracted from the initial sample and prepped for Extraction. In this phase, drugs in hair are processed at a lower concentration compared to other techniques (e.g., urine or oral fluid), which makes hair drug testing the most intricate method to execute.
Confirmation of any positive result from Screening occurs via GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The complete lab process from Accessioning to Confirmation is subjected to review under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation.
