CCP Antibody Testing

CCP CAN HELP DIAGNOSE RHEUMATOID ARTHRITIS
Sometimes it is difficult to diagnose rheumatoid arthritis. In 15% of cases the RF (rheumatoid factor) test is negative. This other antibody, CCP (citrulline protein) can be tested. It shows up in most cases of early RA (rheumatoid arthritis) when the RF might still be negative.

RF NEGATIVE RA
Some people with RHEUMATOID ARTHRITIS (called RA) test negative for RF. In fact, it happens in about 15% of RA patients

POSITIVE CCP
Having a positive CCP test does not mean you have RA.

NEGATIVE CCP
Having a negative CCP test does not mean you do not have RA.

ANTIBODIES
Antibodies are usually thought of as good. Our bodies have millions of antibodies whose job is to watch for and fight off infections of things foreign to your body.
