Hair analysis has gained recognition as an effective method for identifying drug and alcohol consumption. By encapsulating biomarkers within the fibers of the hair shaft as it grows, hair offers an extended timeline of substance use history. When gathered close to the scalp, hair can reveal alcohol and drug use for up to a three-month period. It is straightforward to collect, relatively tamper-resistant, and convenient to transport.
A 1.5-inch segment comprising approximately 200 hair strands (comparable to the diameter of a #2 pencil) near the scalp yields 100mg of hair, which is optimal for screening and confirmation. For detailed analyses, such as EtG or tests exceeding ten panels, 150mg of the sample is preferred. We suggest using a jeweler’s scale for measurement. If scalp hair cannot be obtained, a corresponding quantity of body hair may be used. By head hair, we specifically mean scalp hair, while body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of drug test results involves four principal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preliminary processing of a sample within a lab’s system, which includes ensuring the sample was properly sealed and transported, allocating a unique LAN (Laboratory Accessioning Number), and completing any extra data entry absent in an electronic chain of custody system.
Screening entails an initial rapid assessment for illicit substances. Although Screening is a cost-efficient method for ruling out drug use in most samples, a positive result during screening requires confirmation to be legally valid. Samples that are potentially positive in Screening necessitate a follow-up confirmation.
If Screening indicates a presumptive positive, additional hair is extracted from the initial sample for Preparation. In this phase, drugs are isolated from hair at substantially lower concentrations compared to alternative methods (e.g., urine or oral fluid), making hair drug screening one of the most challenging methods to perform.
Confirmation of any positive screening outcome is achieved via GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation as necessary. The entire laboratory workflow from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair classification and compliance with ISO / IEC 17025 standards.
