Thanks for any help. Bob  <response>: Good Day! What made you say that only 51 of your kidneys are working? The best way to determine differential kidney function is through a Glomerular Filtration Rate GFR done in a Nuclear Medicine Facility. Serum Creatinine is Okay. Area Clear is more than okay. CBC is also okay. Ctscan - A extrarenal pelvis means it is a normal variant and has no clinical significance. Also, the Chat Doctor. All in all I think you are in fine shape Mr. Bob and have a nice day.
