Hair analysis is recognized as a potent method for detecting substance and alcohol consumption. This approach offers an extended history of alcohol and other substances by capturing markers within the growing hair strands. When taken near the scalp, hair can offer a detection period of up to roughly three months for alcohol and drugs. Hair is easy to obtain, relatively hard to tamper with, and straightforward to transport.
A 1.5-inch segment of approximately 200 hair strands (similar in size to a #2 pencil) near the scalp will yield 100mg of hair, the optimal sample size for analysis and verification. For EtG, additional tests, and/or evaluations exceeding 10 panels, 150mg of the sample is advisable. We suggest using a jeweler's scale for accuracy in weighing the sample. If scalp hair is not available, an equivalent amount of body hair can be used. When discussing head hair, it refers exclusively to scalp hair. Body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The four primary steps in the lab processing for drug test results are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial procedure for integrating a sample into a lab's system. This step involves ensuring the sample is sealed and shipped correctly, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional information entry not covered by an electronic chain of custody system.
Screening is a preliminary swift evaluation for the presence of drugs. Although Screening serves as an economical method to eliminate drug use for most samples, a positive screen requires validation to hold up in legal contexts. Any samples that are tentatively positive in Screening necessitate further confirmation.
In cases of presumptive positives in the Screening stage, additional hair is extracted from the initial sample and prepared for Extraction. In this phase, drug compounds are separated from hair at much lower concentrations than other methods (e.g., urine or oral fluid), which makes hair drug screening the most challenging technique to execute.
Validation of any positive screening outcome is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples flagged as presumptive positives are cleaned before confirmation if necessary. The full lab process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation standards.
