Mycotoxin Urine Test Diagnostic Value
- The diagnostic value of a mycotoxin urine test is a topic of ongoing debate, with some studies suggesting its potential usefulness in assessing exposure to mycotoxins 1, 2, 3.
- However, other studies have raised concerns about the validity and reliability of such tests, citing a lack of scientific evidence to support their use in clinical diagnosis 4, 5.
- A study published in 2009 found that mycotoxins can be detected in body fluids and human tissue from patients exposed to mycotoxin-producing molds in the environment, with varying levels of detection depending on the type of mycotoxin 1.
- Another study published in 2010 developed an analytical method for detecting mycotoxins in urine samples, which was sensitive enough to measure mycotoxins and their metabolites at pg ml⁻¹ levels 2.
- In contrast, a 2019 review article argued that the concept of toxic mold syndrome has been disproven, and that there is no evidence to support the use of mycotoxin urine tests in clinical diagnosis 4.
- A 2022 study developed a methodology for determining major mycotoxins in urine samples, which found that 55% of human urine samples analyzed resulted positive for at least one mycotoxin, highlighting the potential for exposure to these toxins 3.
- However, a 2015 report from the CDC noted that the use of unvalidated urine mycotoxin tests for clinical diagnosis is not supported by scientific evidence, and can lead to misinterpretation of results and unnecessary costs for patients 5.
