To answer your questions:
1) The home urine tests may not be as accurate as a formal urinalysis. If there is question about the results, you may want to obtain a urinalysis to confirm any diagnosis.
There is no certainty that there will be blood in the urine due to the cystitis cystica.
A cystoscopy should be considered to evaluate the bladder wall.
2) If there are chronic UTIs, then prophylactic antibiotics can be considered for treatment.
3) This condition is normally benign, and are associated with inflammation. However, I would still obtain the cystoscopy to exclude more serious conditions.
These questions can be discussed with your personal urologist.
Followup with your personal physician is essential.
