Hair testing is now recognized as a robust method for identifying substance and alcohol consumption. Hair captures a prolonged history of substances by embedding biomarkers within the fibers of the hair as it grows. When hair is cut close to the scalp, it can offer up to a 3-month timeframe for detecting alcohol and other substances. Hair is straightforward to gather, somewhat challenging to tamper with, and convenient to transport.
A sample measuring 1.5 inches with around 200 hair strands (approximately #2 pencil thickness) near the scalp will yield 100mg of hair, ideal for analysis and verification. For EtG, add-ons, and tests beyond 10 panels, 150mg of specimen is suggested. It's advisable to weigh the sample using a jeweler’s scale. If scalp hair isn't available, a comparable amount of body hair can be collected. "Head hair" strictly refers to scalp hair, while "Body hair" pertains to other hair types (facial, axillary, etc.).
Process Overview
The laboratory drug test process encompasses four main stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage where a sample is integrated into a lab's system. This involves ensuring that the sample was sealed and shipped accurately, assigning a random LAN (Laboratory Accessioning Number), and completing any additional required data entry absent from an electronic custody chain system.
Screening is a preliminary swift assessment for substances. While cost-effective, Screening primarily dismisses drug use in most specimens, yet a positive result requires confirmation to be legally valid. Any samples indicating a presumptive positive in Screening demand additional confirmation.
With a presumptive positive in Screening, extra hair is extracted from the original sample and prepped for Extraction. During Extraction, substances are drawn from hair at much lower concentrations than other methods (e.g., urine or oral fluid), highlighting why hair drug screening is particularly complex to execute.
GC/MS, GC/MS/MS, or LC/MS/MS confirm any positive screening result. All samples presumed positive are cleansed prior to confirmation if necessary. The entire lab procedure, from Accessioning to Confirmation, is scrutinized according to both the CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 standards accreditation.
Advantages of hair drug testing:
Limitations:
Note: Although termed "hair follicle tests", the test evaluates the hair strand, not the follicle beneath the scalp.
The superiority of hair follicle tests over traditional urine tests is evident in several ways. In Cheney, WA, hair testing offers enhanced detection accuracy, capturing a longer history of drug use. Whereas urine tests may only catch recent drug use, hair tests provide insights into usage over months.
