Anti-citrullinated protein antibodies (ACPAs) are autoantibodies (antibodies to an individual's own proteins) that are directed against peptides and proteins that are citrullinated. They are present in the majority of patients with rheumatoid arthritis.

Anti-citrullinated protein antibodies (ACPAs) are autoantibodies against citrullinated peptides and proteins. The specificity of anti-cyclic citrullinated peptides (anti-CCP), which belong to ACPAs, is 88–98%. Therefore, ACPAs may be reliable markers for the early diagnosis of RA (1).

Anti-CCP is an autoantibody. This means that the patient’s immune system produces antibodies that identify the patient’s cells as foreign material and as a result, attack its own normal cells. These attacks can produce inflammatory symptoms …

For adult rheumatoid arthritis (RA), what is the diagnostic usefulness of anticyclic citrullinated protein antibodies (anti-CCP)? Bottom line. With a specificity of about 96% and a positive likelihood ratio of about 14, anti-CCP assists with the diagnosis of RA.

Dec 15, 2022 · Anti-CCP antibodies are commonly found in rheumatoid arthritis patients and are thought to play a key role in the disease process. Doctors use the anti-CCP antibody test in combination with other tests and symptoms to diagnose rheumatoid arthritis and determine the likely course of the disease.

Antibodies directed to cyclic citrullinated peptides (anti-CCP) are highly specific for rheumatoid arthritis (RA) and can easily be detected in sera by using commercially available immunoassays.

This test looks for CCP (cyclic citrullinated peptide) antibodies in your blood. CCP antibodies can be a sign of rheumatoid arthritis. Learn more.

The Anti-Cyclic Citrullinated Peptide (Anti-CCP) Test is a blood test used to diagnose and assess rheumatoid arthritis (RA). This test detects the presence of anti-CCP antibodies, which are highly specific markers for RA.

What is Anti-CCP? Anti-CCP antibodies are directed against citrullinated proteins; Citrullination results from the post-translational modification (ie. not encoded in the original protein) of the amino acid arginine to citrulline by the enzyme peptidyl arginine deiminase; Anti-CCP assays recognize a number of citrullinated proteins; Role of ...

Jan 31, 2025 · In this article, we explore the significance of the Anti-CCP blood test, how it works, and its role in modern rheumatology. What Are Anti-CCP Antibodies? Anti-cyclic citrullinated peptide (anti-CCP) antibodies are specific proteins produced by the immune system that mistakenly target the body’s own tissues.
