Regarded as a robust method, hair testing plays a key role in identifying drug and alcohol consumption. Hair strands capture biomarkers in their fibers, providing a prolonged record of substance use. When collected near the scalp, hair can reveal substance intake over the past 90 days. The collection process is straightforward, altering the sample is challenging, and shipping is uncomplicated.
Collecting a 1.5-inch sample consisting of around 200 hair strands (similar in size to a #2 pencil) from close to the scalp yields approximately 100mg, optimal for both screening and confirmation. For EtG, extended panels, or when exceeding 10 panels, a 150mg sample size is advisable. Measuring the specimen with a jeweler’s scale is suggested. In instances where scalp hair is unavailable, an equivalent quantity of body hair is suitable. The term head hair specifically pertains to scalp hair, while body hair encompasses other types (like facial or axillary hair).
Process Overview
The laboratory processing involved in obtaining a drug test outcome can be divided into Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step where a sample is entered into a lab’s system. This step involves checking that the sample is properly sealed and sent, assigning a random Laboratory Accessioning Number (LAN), and completing any extra data entry that isn't included in an electronic chain of custody system.
Screening serves as a preliminary assessment for drugs of abuse. Although screening is a budget-friendly method for ruling out drug use in most samples, a positive result requires confirmation for legal standing. Samples with presumptive positive outcomes in Screening undergo additional verification.
In cases where Screening suggests a positive result, more hair is extracted from the initial sample for the Extraction process. Drugs are isolated from hair at significantly lower levels than other methods like urine or oral fluid tests, contributing to the complexity of hair drug testing.
Verification of any positive results from Screening is achieved through GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples identified as presumptive positives are cleansed before confirmation if necessary. The full laboratory workflow, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair guidelines and adherence to ISO / IEC 17025 standards.
