Usual CRP?
I am not sure there is such a thing-it varies so much. When I first saw my current rhuemy my GP had me on 30 mgs per day of pred-I had been on it for 42 days, and my CRP was still 50. My Rhuemy was very unhappy with that.
When I am stable and controled its 4-10.
When I have an infection it can be really high-infections can actually cause higher numbers then inflamatory arthritis.
