Hair examinations have gained recognition as an effective approach for identifying drug and alcohol consumption. Hair strands archive an extended chronology of alcohol and drug intake by capturing biomarkers within the fibers as they grow. When retrieved near the scalp, hair can reveal drug and alcohol use for roughly a 3-month timeframe. Collecting hair is straightforward, relatively challenging to tamper with, and easy to transport.
A 1.5-inch fragment consisting of about 200 hair strands (equivalent in size to a #2 pencil) close to the scalp provides 100mg of hair, which is the optimal sample for testing and validation. For EtG add-ons and/or tests with more than 10 panels, a specimen quantity of 150mg is preferred. It is advisable to weigh the specimen using a jeweler’s scale. Should scalp hair be lacking, an equivalent amount of body hair can be gathered. When discussing head hair, it specifically pertains to scalp hair. Body hair denotes all other hair categories (facial, axillary, etc.).
Process Overview
The drug test result processing in a laboratory comprises four fundamental stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a laboratory's framework. This step includes ensuring the sample's proper sealing and shipping, allocating a distinct LAN (Laboratory Accessioning Number), and finalizing any extra data entry absent from an electronic chain of custody system.
Screening conducts an initial rapid assessment for potential drug abuse. While Screening serves as an economical method for excluding drug usage in the majority of samples, a positive screen must be verified for court admissibility. Samples that appear positive during Screening necessitate a subsequent confirmation.
Should a sample yield a presumptive positive result during the Screening stage, additional hair is extracted from the initial batch and prepped for Extraction. During this phase, drugs are drawn out of hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), making hair drug screening the most complex methodology to execute.
Positive screenings are confirmed via techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo a washing procedure before confirmation as required. The complete process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: While often referred to as "hair follicle tests", the examination actually analyzes the hair strand, not the follicle beneath the scalp
Compared to traditional urine tests, hair follicle testing in Huntsville, MO, offers superior detection accuracy. Hair tests are less likely to be influenced by external factors, such as fluid intake or diet. This makes them more reliable when used for drug screening purposes, ensuring a higher confidence level in results.
The advanced technology behind hair follicle testing provides enhanced dependability in identifying longstanding drug use. It beats urine testing by offering a more robust detection window, capturing a wider picture of an individual's substance history.
