Elevated CRP...again

I wonder how accurate this test is as far as pinpointing the inflammation.  I had this labwork drawn on Monday of last week when it was still thought that I had a kidney infection which in turn turned out to be that SI joint issue where I had lots of swelling in my muscles in my back/pelvic region.  Could this have been what made my level elavated or is it the fact that even in my scope last year I showed signs of active CD?

 

CRP is used as a general screen, it will not give any indication of where the inflammation is just that there is some tissue damage/inflammation somewhere in your body at some point recently.
It will not tell you if that inflammation is at it's peak. It's a helpful tool for establishing that there is a problem, but not what that problem is.
It could be either causing the elevation in it's level.
