Hair testing is recognized as an effective tool for identifying drug and alcohol usage. Hair offers an extended history of alcohol and drug intake by securing biomarkers within the fibers of the growing hair. When sourced near the scalp, hair can reveal up to a 3-month detection range for drugs and alcohol. Hair collection is straightforward, tough to tamper with, and easy to transport.
A 1.5-inch cut of about 200 hair strands (comparable to a #2 pencil) nearest the scalp yields 100mg of hair, which is the optimal sample for analysis and verification. For EtG, enhancements, and/or evaluations over 10 panels, a sample of 150mg is advised. We advocate using a jeweler’s scale for the specimen weighing. If scalp hair is absent, an equivalent volume of body hair can be used. When discussing head hair, we mean scalp hair exclusively. Body hair includes all other forms (facial, axillary, etc.).
Process Overview
The key stages in processing a drug test result in the lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of processing a sample into a lab's system. That involves confirming the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain of custody system.
Screening is an initial rapid assessment for drug abuse. While Screening is a cost-efficient technique for excluding drug use in most samples, a positive screen needs confirmation to be valid in court. Samples that show a presumptive positive in Screening require secondary confirmation.
In the event of a presumptive positive in the Screening stage, additional hair is drawn from the initial sample and readied for Extraction. During this phase, drugs are extracted from hair at a much reduced concentration than other methods (e.g., urine or oral fluid), making hair drug testing the most challenging method to execute.
GC/MS, GC/MS/MS, or LC/MS/MS is used to verify any positive screening outcome. All presumptive positive samples are cleaned before confirmation as needed. The complete laboratory process from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair classification and the certification to ISO / IEC 17025 standards.
