The most characteristic laboratory abnormalities in patients with psoriatic arthritis are elevations of the erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) level. The results from these laboratory tests help to track the activity of the disease by measuring inflammation.
Can inflammatory markers be normal with psoriatic arthritis?
High levels of CRP can be a sign of autoimmune diseases like RA, lupus and PsA. A normal ESR and CRP result can’t rule out a PsA diagnosis, because about 60% of people with this condition don’t have elevated levels of these inflammatory markers.
What autoimmune disease has high CRP?

Will CRP increase with any inflammation?
