Hi: (See Labs below) In your opinion, do I have a kidney infection? I have a history of kidney infections. 2-3 per year for the last 40+ years. My kidneys have been bugging me and, between early December 2013 to l0 July 2014, saw my doctor & had labs done 4 times. 7-8 months and several phone calls and emails later, he sent me an email saying Most recent U/A was negative for infection . I went online to scheck my labs. All lab results since Dec 2013 are about the same as the last ones (Shown below) except for the following : each eGFR lower than previous, starting at 59.9 in Dec 2013 dropping to 41.3 in Jul 2014; Bun was 20 now 30; Creatinine went up from .96 to 1.32; Bacteria went from few(2-5) to Many( 15) and Protein increased from none to 30.
