Hi folks, I'm writing because my father had a positive urovision/fish test 3 months ago and the physician did a cystoscopy and biopsied bladder wall and far up into kidney's -- he has cysts in his Kidney's. Biopsy results came back negative. He just got the results of his 3 mos follow-up urovision/fish test and it is again positive.
I'm writing to ask folks if they have experiened false/positives of this nature with this particular test? While his markers are low, I'm concerned that this is the second now that is positive.
Any feed back or suggestions on how to proceed would be welcome. Physician wants to do another in three months.
