Hi Rudy and Welcome Back!!
I personally am unaware of ever having an increased CRP myself, but recently had the test ordered and it wasn't done...that's a whole other story.
However the CRP, or c-reactive protein is a protein that's produced by the liver and is only present when a person is having some form of acute inflammation.
I did a bit of research on this and found that "the most important role of CRP is it's interaction with the "complement" system, which is one of the body's immunologic defense mechanisms."
I hope this gives you something to start with in your discussions with your wife's Dr. And to aid in this, I've cited below 2 most reliable sources for you to look at...I'm hoping this helps a little and please wish your wife only the very best~I really hope they get to the bottom of this quickly and please keep us updated!
Good Luck and Big Texas Hugs, Teri
PS Does your wife have any history of Heart Disease, Rheumatoid Arthritis? These are only a couple of things that can be making this CRP level go up~there are others.
