Anti-CCP

Anti-CCP Test

Anti-CCP is the gold standard serological test for rheumatoid arthritis. Early detection through proactive screening enables treatment before irreversible joint damage occurs.

Doctor's Assessment Included

Anti-CCP: what this test measures

This test detects antibodies against cyclic citrullinated peptides. Citrullination is a protein modification that occurs in inflamed joints, and the immune response to these modified proteins is characteristic of RA.

Anti-CCP: why this value matters

Anti-CCP has approximately 95% specificity for RA, making it the most specific serological marker. Its presence predicts more severe, erosive disease, enabling early aggressive treatment to prevent joint damage.

Anti-CCP: how the blood test works

Referral: No GP referral needed. After the order we arrange the referral through ZorgDomein, within one business day; orders after 17:00 or at the weekend start on the next business day. ZorgDomein emails a barcode, and that barcode is what the draw site needs.
The draw: A blood draw from a vein in the arm, at a partner laboratory's draw site. No home kit, no finger prick.
Which test: on its own €52,-
Where: 650+ draw sites run by independent laboratories across the Netherlands. Draw sites

Anti-CCP: when is testing worthwhile?

Testing could be indicated for suspected RA: symmetric joint pain and swelling (especially small joints of hands and feet), morning stiffness lasting over 30 minutes, or positive rheumatoid factor needing confirmation.

Anti-CCP: symptoms of a high or low value

Low Levels

A negative anti-CCP does not exclude RA. Approximately 20-30% of RA patients are seronegative (negative for both RF and anti-CCP).

High Levels

A positive anti-CCP in the context of joint symptoms strongly supports RA diagnosis. It predicts more aggressive disease with joint erosions and may be present years before clinical symptoms develop.

Anti-CCP: lifestyle and this value

If anti-CCP positive with symptoms, early rheumatology referral is crucial. Modern RA treatment aims to achieve remission through early, aggressive therapy. Regular exercise, joint protection techniques, and smoking cessation are important.

Anti-CCP: frequently asked questions

Is anti-CCP better than rheumatoid factor?

Anti-CCP is more specific (95% vs 80%). RF can be positive in many conditions. Anti-CCP is more useful for confirming RA and predicting disease severity.

Can anti-CCP be positive before symptoms?

Yes. Anti-CCP can be detected up to 10 years before clinical RA develops, making it valuable for identifying at-risk individuals.

Does a high anti-CCP level indicate worse disease?

Higher titres are associated with more aggressive, erosive disease. However, treatment decisions depend on the overall clinical picture, not antibody levels alone.
