Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. It captures a comprehensive overview of alcohol and substance use by embedding biomarkers within the fibers of the developing hair strand. When extracted near the scalp, hair offers an approximate 3-month period for detecting alcohol and other substances. Collecting hair is straightforward, tampering is relatively challenging, and transportation is convenient.
A 1.5-inch portion consisting of roughly 200 strands (comparable to the girth of a #2 pencil) closest to the scalp yields 100mg of hair, the optimal sample quantity for initial testing and subsequent confirmation. For EtG, supplementary tests, or panels exceeding 10, a specimen weighing 150mg is preferable. Using a jeweler’s scale is suggested for measuring the specimen. In cases where scalp hair is absent, a comparable quantity of body hair can be utilized. References to head hair specifically pertain to scalp hair. Body hair denotes all other types (such as facial or axillary).
Process Overview
The laboratory procedure for processing a drug test comprises four essential stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning constitutes the initial incorporation of a sample into the laboratory’s system. This involves ensuring the sample’s seal and proper shipment, assigning it a unique LAN (Laboratory Accessioning Number), and finalizing any additional data inputs not supplied by an electronic chain of custody system.
Screening entails a preliminary rapid assessment for substances of abuse. Even though Screening is a budget-friendly method to dismiss drug use in most samples, a positive outcome in Screening necessitates verification to be court-admissible. Any sample indicating a presumptive positive in Screening mandates a secondary confirmation.
Should a sample yield a presumptive positive during Screening, additional hair is extracted from the primary specimen and readied for Extraction. During this phase, substances are removed from hair at considerably lower concentrations compared to other methodologies (such as urine or oral fluid), affirming hair drug screening as the most complex method to execute.
Verification of any positive Screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens undergo washing before confirmation as needed. The comprehensive laboratory process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair classification and compliance with ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Frequently termed as "hair follicle tests", the examination evaluates the hair strand, not the follicle beneath the scalp.
Hair follicle testing provides a more comprehensive analysis than urine tests. Why choose hair over urine? The accuracy and detection capabilities of hair testing far surpass traditional urine tests, providing a detailed look into one's substance history. This is especially significant in environments where accuracy and dependability are critical.
The major advantage of hair follicle drug tests lies in their ability to identify drug use spanning up to 90 days. This extended window offers employers a broader understanding of an individual's substance use patterns, which is crucial for assessing long-term behaviors. With this approach, businesses can gain deeper insights that a typical urine test may overlook, fostering informed employment decisions.
Hair follicle tests are inherently tamper-resistant, mitigating risks associated with sample adulteration. By choosing this method, employers receive more reliable and undeniable results. The structure of hair testing, including its observed collection procedure, enhances its robustness, making it one of the most secure ways to screen for substance use, rendering efforts to cheat ineffective.
