How many blood tests are taken to test for rheumatoid arthritis?

Basic two. Rheumatoid factor (rf) and cyclic citrinullated peptide (ccp) are the two tests that help confirm a diagnosis of rheumatoid arthritis. Other tests are done to measure inflammation, determine which drugs may be used, etc. Note: the rf and ccp only help confirm the diagnosis. The presence of an antibody does not definitively make the diagnosis. Also, persons may have RA and be rf and ccp negative.
See below. There are a few tests that can help in the determination of rheumatoid arthritis. One is a rheumatoid factor which is not always positive. Often a test called a sed rate is done and a CRP both of which are measures of inflammation in the body and are often elevated in ra. One more test is called an anti ccp antibody which is a more sensitive test that rheumatoid factor.
