Anti-CCP antibody

Anti-CCP antibodies are proteins produced by the immune system that target specific components in the joints, particularly citrullinated proteins. Their presence is strongly associated with rheumatoid arthritis (RA), an autoimmune disorder where the immune system mistakenly attacks joint tissues. Detecting Anti-CCP antibodies helps doctors diagnose RA, often before significant joint damage occurs. They are highly specific for RA, meaning their presence suggests the disease, though not everyone with RA tests positive. Measuring these antibodies aids in diagnosing, assessing disease severity, and guiding treatment decisions.
