Cyclic Citrullinated Peptide Antibody

Cyclic Citrullinated Peptide Antibody IgG 

This test is used to diagnose and measure the severity of rheumatoid arthritis.  This test often follows a rheumatoid factor test and it can also give some insight into the likelihood of developing this condition at a later date depending upon the results.  The presence of cyclic citrullinated peptide antibodies alongside a positive rheumatoid factor test will likely mean that rheumatoid arthritis is present, while a negative rheumatoid factor test may mean it is not present yet, but the risk of it occurring is high.
