[|Human|] Hi to all. Hope everyone is doing great! I have a question concerning or relating to kidneys. I recently have been having blood show up in my urine and it scared me the first time I discovered it. I am a 28 y/o male reasonably healthy and all. I was so afraid i immediately set up an appointment to be seen. urine samples and ct scan done. All came back negetive. But without dye due to allergic reaction. My creatinine level is 0.9 and gfr was in normal range. I am worried the ct scan was not accurate enough is all. what do you think?
[|AI|]  Hello, Thanks for the query to Chat Doctor. Forum. Since you mentioned that blood in urine were present, and you got in C T SCAN without dye. Main question is report normal without dye? It depends upon the nature of disease in kidney, e.g. If tumor present in kidney than it is very difficult to visualize without dye (contrast media). In the case only option I'd there please get in M R I for urinary tract system. However, according to my experience urine may contain blood due to many reasons. But in your case as serum creatinine level is normal, G F R is also normal so need not worry. If blood reoccurs in urine then consult a nephrologist and get his opinion. Good luck.
