Hi Silk,
Gee my OB/GYN does the test every year...i don't think it makes a difference whether you have a real bladder or neo or whatever. The test is sometimes given with a neo or other diversion if you are symtomatic....but
There can be false-positive and false-negative results. Using the right collection technique, avoiding certain drugs, and observing food restrictions can reduce errors. And even with the positive ones they often don't find the reason??
I know you probably know all this stuff but i'll throw it out there anyway as I didn't realize Vitamin C could alter the test. Silly me.
