There's no way to tell what causes the inflammation and no way to rule out another cause. Let's say you had some minor surgery and you didn't tell your doctor. He collects your CRP and well it's high. That must mean your PsA is active! There are lots of things things that can cause an elevated CRP. The test needs to be done in conjunction with others and a physical exam. And even with that it's hard to say definitely that the PsA is causing it. Not to mention there are drugs that reduce CRP levels without reducing disease.
