Is it common to measure c-reactive protein in diagnosing majjor organ disease?

Not common...: The thing about c-reactive protein is that it's not too specific - meaning, if it's elevated, it could be elevated for a bunch of reasons: infection, inflammation, etc... And it doesn't tell you which organ system has the infection or inflammation. We measure it sometimes in the hospital, but it's not one of those i've seen regularly ordered by primary care physicians as an outpatient.
