ANSWER: It is possible that taking D-mannose could affect the results of a urine test, but this would depend on the specific test being performed and how much D-mannose is taken. D-mannose is a type of sugar that is sometimes used as a natural remedy for urinary tract infections and other conditions that affect the urinary tract.

Because it is a sugar, it can affect the concentration of sugar in the urine. This could potentially interfere with some urine tests that measure the concentration of sugar in the urine, such as a urine glucose test.

However, the effects of D-mannose on urine tests are not well-studied, and it is always important to talk to a healthcare provider before using any new treatment, including D-mannose, and before undergoing any medical testing.
