Hair analysis is now viewed as an effective means for detecting drug and alcohol consumption. Hair captures biomarkers within the fibers of the growing strand, offering an extended record of substance use. When gathered near the scalp, hair can indicate alcohol and drug usage within roughly the last 90 days. It is easy to collect, hard to manipulate, and convenient to transport.
A sample measuring 1.5 inches in length and containing about 200 strands (comparable in size to a #2 pencil) near the scalp yields 100mg of hair, the recommended quantity for testing and confirmation. For EtG, supplementary tests, or panels beyond ten substances, 150mg of hair is advised. Utilize a jeweler's scale to measure the specimen's weight. If scalp hair isn't available, a comparable amount of body hair might be taken. When discussing head hair, we mean scalp hair specifically, while body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The drug test result processing encompasses four main stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes integrating a sample into a laboratory's system. This process ensures the sample was sealed and transported correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any additional required data entry missing from a digital chain of custody system.
Screening entails an initial rapid drug use check. While Screening is a cost-effective method for ruling out drug use for most samples, a positive screen must be confirmed to be accepted in court. Any samples considered presumptively positive in Screening necessitate a secondary confirmation.
If a sample is presumptively positive in the Screening phase, additional hair is extracted from the original sample for the Extraction process. During this stage, drugs are extracted from hair at a significantly lower concentration than other methods (e.g., urine or oral fluid), which makes hair drug screening the most challenging method to execute.
Confirmation of any positive screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS methods. All presumptive positive samples are cleansed before confirmation when necessary. The full laboratory process from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and pursuant to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: The term "hair follicle tests" is a misnomer; the analysis targets the hair shaft, not the follicle beneath the scalp.
