What is the most significant blood test to diagnose rheumatoid arthritis?

Is Anti CCP test accurate?
With a specificity of about 96% and a positive likelihood ratio of about 14, anti-CCP assists with the diagnosis of RA. It is present in only a quarter to half of patients before or at diagnosis, so a negative result does not rule out RA. It can also predict aggressive joint erosion.
How is anti CCP test performed?
