Hair testing has increasingly gained recognition as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged history of substance use by embedding biomarkers within the fibers of the hair strand as it grows. When gathered near the scalp, hair can reveal substance use over a period of approximately three months. Collecting hair is straightforward, relatively resistant to tampering, and convenient for transportation.
A sample measuring 1.5 inches and containing around 200 hair strands (roughly the diameter of a #2 pencil) adjacent to the scalp will yield 100mg of hair, which is the optimal amount for both screening and confirmation. For EtG, additional tests, and/or assessments exceeding 10 panels, a 150mg sample is advisable. We suggest weighing the specimen using a jeweler’s scale. If scalp hair is not accessible, an equivalent volume of body hair may be utilized. References to head hair pertain exclusively to scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).
Process Overview
The laboratory processing for drug test results encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into a laboratory’s system. This process ensures the sample was appropriately sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and fills any missing information not captured by an electronic chain of custody system.
Screening provides an initial cursory check for drug use. While Screening is a budget-friendly approach to exclude drug use in most samples, a positive outcome requires confirmation for legal admissibility. Any samples exhibiting presumptive positive results in Screening mandate a secondary confirmation.
If a sample registers as presumptively positive during Screening, additional hair is sourced from the original sample for Extraction. During Extraction, drugs are isolated from hair at a significantly lower concentration compared to other methods (e.g., urine or oral fluid), rendering hair drug testing as the most challenging methodology.
Confirmation of any positive screen is executed via GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positive results undergo a washing stage before confirmation as appropriate. The entire laboratory sequence from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and accreditation pursuant to ISO / IEC 17025 standards.
