I think that I have a UTI, I have had one before, the same urge to urinate, burning sensation, blood in urine, etc. I have out off going to the Dr. and have been drinking 100% cranberry juice and taking Uricalm to numb the burning sensation. It is really effective though I can tell it is still not wuite right when I pee. I am going to the Dr. today and wanted to know if the Uricalm would effect any tests done on my urine sample?
