what are the chances of rheumatoid arthritis if anti CCP is positive
Antibodies to Anti-Cyclic Citrullinated Peptides (ACPA). These antibodies (anti-CCP) have been around since the mid 2000âs. They are useful in that they arenât usually found in diseases other than RA. So if you have a positive anti-CCP then chances are youâre dealing with RA.The presence of these antibodies may predict the development of RA and can be detected in healthy individuals years before the onset of clinical RA. They are also a marker for more severe disease. A very high titre (level) of rheumatoid factor (in the 100âs or 1000âs) makes it more likely that you have RA. 2  A rheumatoid factor can be present years before the onset of rheumatoid arthritis.
