Which of the following can cause a false positive result in glucose testing?

In glucose testing, certain substances can interfere with the accuracy of the test results, leading to false positives. Peroxide is a substance that can oxidize glucose, leading to the production of a color change that may be interpreted as a positive glucose result. This chemical reaction may mimic the presence of glucose even when it is not actually present in the sample.

While other substances listed may have varying effects on urine tests, peroxide specifically can directly interfere with the glucose detection mechanism, making it a notable cause of false positives in glucose screening tests. Understanding the chemical reactions that occur during these tests helps highlight why certain substances can skew results, allowing for better interpretation and management of diagnostic testing.
