Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair offers a prolonged record of alcohol and other substances by capturing biomarkers within the fibers of the maturing strand. When sourced near the scalp, hair can reflect a detection period of up to roughly 3 months for both alcohol and other substances. Hair collection is straightforward, somewhat challenging to alter, and convenient for shipping.
A sample of 1.5 inches with approximately 200 hair strands (comparable to the girth of a #2 pencil) near the scalp yields 100mg of hair, which is ideal for initial and confirmatory testing. For EtG, additional testing, or tests beyond 10 panels, collecting 150mg of the sample is advisable. It's suggested to measure the sample using a jeweler’s balance. In cases where head hair isn't available, a matching amount of body hair can be used. "Head hair" specifically refers to scalp hair, while "Body hair" pertains to other hair types (like facial, axillary, etc.).
Process Overview
The lab processing of a drug test result encompasses four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the preliminary processing of a sample into a laboratory's framework. This phase ensures the sample was properly sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and fills in any extra data not covered by an electronic chain of custody system.
Screening provides a preliminary scan for drug usage. While this step offers a cost-efficient mechanism to rule out drug use in most samples, a positive finding in Screening needs further validation for legal admissibility. Samples that screen as presumptively positive must undergo additional confirmation.
In cases of presumptive positivity during Screening, additional hair is taken from the initial sample for the Extraction step. During this phase, drugs are extracted from hair at concentrations substantially lower than those in other methods (such as urine or oral fluid), which is why hair drug testing is the most intricate method to conduct.
For verifying any positive Screening result, procedures like GC/MS, GC/MS/MS, or LC/MS/MS are employed. Presumptive positive samples undergo a washing process before confirmation as needed. The entire lab workflow from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation standards.
