Hair analysis is increasingly recognized as a significant method for identifying drug and alcohol consumption. Hair can offer an extended overview of substance use by encapsulating biomarkers within the strands of the hair as it grows. When cut near the scalp, hair can reveal drug and alcohol usage history for a duration of up to 90 days. Hair is easy to gather, challenging to tamper with, and convenient for transport.
For optimal examination and validation, a 1.5-inch segment of about 200 hair strands (similar to the thickness of a #2 pencil) next to the scalp yields approximately 100mg of hair. For EtG tests and other specialized analyses involving more than 10 panels, a 150mg sample is recommended. It's advised to measure the specimen using a jeweler's scale. If scalp hair isn't accessible, an equivalent quantity of body hair can be utilized. The term head hair specifically refers to hair from the scalp, while body hair denotes any other hair types (such as facial or axillary hair).
Procedure Summary
The process of analyzing a drug test result in the lab includes these primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step where the sample is integrated into the laboratory’s workflow. This step verifies that the package was properly sealed and sent, assigns an arbitrary LAN (Laboratory Accessioning Number), and fulfills any supplementary data entry that wasn’t covered by an electronic chain of custody framework.
Screening is the second step, providing a preliminary assessment for substances of abuse. Although Screening is cost-efficient for eliminating drug use in most cases, any positive result necessitates further validation for legal acceptance. Samples that show a potential positive in Screening require a follow-up confirmation test.
If a Screening outcome suggests a positive, additional hair is taken from the initial sample for the Extraction phase. Here, substances are derived from hair at significantly lower concentrations than other methods (like urine or oral fluid), making hair drug testing one of the most intricate methodologies.
GC/MS, GC/MS/MS, or LC/MS/MS is used for authenticating any positive from the Screening phase. Before final confirmation, all potentially positive samples undergo cleaning as applicable. The entire testing sequence from Accessioning to Confirmation adheres to CAP (College of American Pathologists) Hair standards along with ISO / IEC 17025 benchmarks.
