Will taking Azo alter the results of a urine test for a UTI?

The common "dip stick" urine test that we use for testing urine for infection and other things is often inaccurate due to the AZO changes the color of the sticks. The machine for the urine test can often be inaccurate for this. I have seen falsely elevated readings for Glucose and Liver byproducts on the test.

A gynecologist I used to work for told me that Pyridium can definitely alter a urinalysis (cause it to be inaccurate).

Azo won't have any affect on the urine test results, it only treats the symptoms of the infection thus leaving the amount of bacteria in your system to be unaltered. The same is true for any bladder soothers you may take for UTI pain.

It can effect a dip stick test because it discolors your urine but it should effect a culture.

It might change the color.it won't change the number and type of cells in urine.
