This is the third time I have tried to find out from my doctors office advice about what to do about the urinalyses that mentions it contains blood. (not visible to me) I called early to ask to be fitted in today to talk to him in person. No call so far. Twice I have been told, "but there is no infection". I've told the nurses that called back then, I'm not qualified to advise myself. What should I do? For 14 years we've always been cordial.
