Hair analysis is regarded as an effective method for identifying drug and alcohol consumption. Hair creates a prolonged account of substance use by embedding indicators within the fibers of the hair as it grows. When collected near the scalp, hair samples offer an approximate 3-month timeframe for detecting alcohol and drugs. Collecting samples is easy, tampering is challenging, and transportation is straightforward.
A 1.5-inch strand composed of roughly 200 hairs (comparable to the girth of a #2 pencil) taken nearest the scalp yields 100mg of hair, the perfect amount for both initial tests and confirmation. For EtG, additional screens, and/or testing that exceeds 10 panels, a specimen weight of 150mg is advisable. Measuring the specimen using a jeweler’s scale is suggested. If head hair isn't an option, a corresponding amount of body hair can be used. When discussing head hair, we specifically mean scalp hair. Body hair encompasses all other types (such as facial and axillary).
Process Overview
The laboratory analysis of a drug test result entails four principal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial incorporation of a specimen into a lab system. This step verifies proper sealing and shipment, assigns a LAN (Laboratory Accessioning Number) at random, and completes any further data requirements not covered by an electronic custody chain.
Screening is a preliminary rapid evaluation for substance abuse. Although Screening is an economical method to exclude drug use in most cases, a positive outcome requires confirmation to be court-admissible. Presumptive positives from Screening necessitate a secondary validation.
If Screening suggests positivity, additional hair is retrieved from the original specimen to prepare for Extraction. Here, substances are extracted from hair at significantly lower concentrations than in other practices (e.g., urine or saliva), highlighting the complexity of hair drug screening.
Positive screening is verified through GC/MS, GC/MS/MS, or LC/MS/MS. Samples presumed positive undergo required washing before confirmation. The full laboratory process from Accessioning to Confirmation adheres to both CAP (College of American Pathologists) Hair guidelines and ISO/IEC 17025 accreditation.
