Hair screening is increasingly recognized as a robust method for identifying drug and alcohol consumption. By capturing biomarkers within the fibers of the developing hair strand, hair preserves a long-term record of substance use. When samples are obtained close to the scalp, they can offer a detection timeframe of up to around three months for substances like alcohol and drugs. Collection of hair is straightforward, somewhat resistant to tampering, and can be easily transported.
A 1.5-inch portion of roughly 200 hair strands (approximately resembling a #2 pencil) nearest to the scalp produces 100mg of hair, which is the optimal quantity for both screening and confirmation. For tests involving EtG, additional checks, or those beyond 10 panels, a specimen size of 150mg is advisable. It's suggested to use a jeweler’s scale for weighing the specimen. If scalp hair isn't present, equivalent body hair can be utilized. "Head hair" specifically refers to scalp hair, whereas "body hair" denotes all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four essential steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a lab's system. This stage includes ensuring the sample was properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any needed data entry not covered by an electronic chain of custody system.
Screening is a preliminary review for the presence of drugs of misuse. Although Screening is a cost-effective technique to exclude drug usage for most samples, a positive result must be validated to be considered court-admissible. Samples that yield a presumptive positive in Screening necessitate subsequent confirmation.
If Screening indicates a presumptive positive result, additional hair is collected from the initial specimen for Extraction. This stage involves retrieving drugs from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening the most challenging method to execute.
Positive screening results undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Before confirmation, all presumptive positive samples are cleansed as required. The comprehensive lab process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and accreditation according to ISO / IEC 17025 standards.
