Anti CCP (Anti-Cyclic Citrullinated Peptide)

The Anti-Cyclic Citrullinated Peptide (Anti-CCP) test is a highly specific blood test used primarily to diagnose Rheumatoid Arthritis (RA). It is incredibly helpful because it can detect the presence of RA-specific antibodies often years before physical symptoms, like joint swelling or stiffness, fully develop. Unlike other general markers of inflammation, the Anti-CCP test is remarkably accurate at distinguishing RA from other types of joint pain, allowing doctors to start aggressive treatment early.
