High iga, low urea, ct found lesions on kidney and urinated a slight bit of blood?

Talk to doc.: Hard to put together without more info. Apparently you are already seeing someone who is working on this. I believe CT and blood in urine may be related but that the other two findings are not ALTHOUGH I do not understand why someone would draw an IgA level without a good reason. There is more to your story than we know. Talk to your doc.
