Hair testing is widely recognized as an effective method for identifying drug and alcohol consumption. It offers a detailed timeline of substance use by encapsulating biomarkers in the fibers of a growing hair strand. When collected near the scalp, hair samples can reveal drug and alcohol usage within an approximate 90-day period. Hair is easy to obtain, not easily adulterated, and simple to transport.
A 1.5-inch sample of approximately 200 hair strands (comparable to the width of a #2 pencil) taken from the scalp provides 100mg, which is the optimal amount for both screening and confirmation. For EtG, additional analyses, or tests beyond 10 panels, a specimen size of 150mg is advised. We suggest measuring the specimen using a jeweler’s scale. If scalp hair is not available, a similar quantity of body hair can be gathered. When mentioning head hair, we specifically mean scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory process for analyzing a drug test consists of four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step, involving the integration of a sample into the laboratory’s system. This step ensures that the sample is properly sealed and delivered, assigns a unique LAN (Laboratory Accessioning Number), and completes any missing data entry that an electronic chain of custody system may not provide.
Screening includes a preliminary assessment for substances of abuse. Though Screening efficiently eliminates drug usage in most samples, a positive Screening result requires confirmation to be valid in a legal setting. Any samples with preliminary positive results necessitate further confirmation.
For samples with presumptive positive results in the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. This phase involves extracting drugs from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), which makes hair drug screening the most challenging methodology.
Confirmation for any positive Screening result is carried out using GC/MS, GC/MS/MS or LC/MS/MS techniques. All samples presumed positive are cleaned before confirmation when necessary. The entire process from Accessioning to Confirmation is reviewed following both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards.
