Kidney damage
What would cause pain/discomfort in a kidney, that wouldn't show up on a kidney function blood test?
I need it to be something that wouldn't be discovered right away. So far, I'm thinking of a benign tumor. Would a benign tumor impact the results of a kidney function blood test?
Search terms: kidney disease, kidney ailments, kidney function blood test, kidney ailment not showing up on blood test, kidney damage, hidden kidney damage, underlying kidney damage, underlying kidney disease, benign tumor in kidney, benign tumor kidney test results, blood test results benign tumor, kidney blood test results benign tumor.
While searching with these terms gave me lots of information, I could not figure out the answer to my obscure question.
*EDIT* Preferably a condition that would not show up on a urine test, either. Something that can only be found via ultrasound. Character is a wizard whose magical aura disrupts medical machinery, but ends up having a kidney problem that would have been fine had they been able to see it, but since they can't do imaging on him all they have to go on is blood/urine tests, which show up clean. That's why I was thinking along the lines of a benign tumor, because a malignant one would probably show on the blood test.
So, would a benign tumor impact the results of a blood test?
