Hair analysis is recognized as an efficient means for identifying alcohol and drug consumption. Hair maintains a long-lasting record of alcohol and drug presence by encasing biomarkers within its strands as it grows. When hair is sampled near the scalp, it can reveal usage of alcohol and drugs over an approximately 3-month period. Collecting hair is straightforward, challenging to tamper with, and conveniently shipped.
A 1.5-inch segment, approximating a bunch of 200 hair strands (similar to the diameter of a #2 pencil) closest to the scalp, will yield a 100mg specimen, which is optimal for both preliminary screening and definitive testing. For EtG, additional evaluations, or tests exceeding 10 panels, a 150mg specimen is advised. It's beneficial to weigh the sample using a jeweler's scale. If scalp hair is inaccessible, a comparable portion of body hair can be collected. When referencing head hair, it pertains solely to scalp hair, whereas body hair denotes all additional types of hair (such as facial, axillary, etc.).
Process Overview
The procedure for lab-processing drug test results encompasses four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial integration of a specimen into a lab’s system. This process includes confirming the sample was properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain of custody system.
Screening provides a preliminary rapid evaluation for substances of abuse. Although Screening economically eliminates drug presence in most specimens, any positive indication requires confirmation to be valid in legal settings. Any specimens showing possible positives in Screening necessitate additional confirmation.
Should a sample exhibit possible positivity during Screening, additional hair is extracted from the initial sample and prepared for Extraction. Here, substances are pulled from hair at significantly reduced concentrations compared to other testing methods (e.g., urine or oral fluid), rendering hair drug testing among the most complex methodologies.
Positive screening results require Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. All possibly positive samples undergo washing before confirmation if needed. The complete lab process from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair criteria and the accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Though commonly termed "hair follicle tests," the evaluation focuses on the hair strand rather than the follicle beneath the scalp.
When comparing hair follicle testing to traditional urine tests in Cleaton, KY, hair testing stands out in terms of superior detection. Hair analysis offers a longer detection period compared to urine, accommodating up to 90 days of historical substance use data.
This longer detection span allows for capturing intermittent usage that might be missed with urine tests. Furthermore, the stability of hair samples over time enhances the reliability and integrity of the results.
Hair follicle testing provides an extended detection window, making it a valuable tool for employers in Cleaton, KY. By analyzing hair samples, one can trace substance use history over a period of up to 90 days, offering a comprehensive insight into an individual’s past usage patterns.
Employers benefit from this wide detection span by gaining a more complete understanding of their potential or current employees' substance use habits, contributing to informed employment decisions and workplace safety.
A significant advantage of hair follicle testing in Cleaton, KY, is its resistance to tampering. The method circumvents issues commonly associated with other testing techniques, such as sample adulteration or substitution.
Hair samples are collected under observation, ensuring the authenticity of the sample. This observed collection removes opportunities for manipulation, thereby providing employers and officials with reliable and trustworthy test results.
The convenience of hair follicle testing is amplified by the widespread availability of testing centers, including those in Cleaton, KY. Whether nationally or locally, individuals have easy access to efficient testing facilities that ensure hassle-free experiences.
