Bilirubin testing in urine dipstick uses which reaction, and which interferences can occur?

Bilirubin on urine dipsticks is detected with a colorimetric reaction that is implemented by the Icotest format. The key idea here is that this method can produce a positive result not only when bilirubin is present but also due to other substances or factors in the urine that trigger the same color change, leading to false positives. That potential for false positives is what makes this option the best match. Other statements imply a different reaction mechanism or claim no interferences, which don’t align with how this dipstick readout behaves in practice.
