CCP antibody, or cyclic citrullinated peptide antibody, is an autoantibody found in the blood of individuals with autoimmune diseases, especially rheumatoid arthritis. It targets cyclic citrullinated peptides, which are modified proteins involved in joint inflammation. CCP antibody testing is used to assist in the diagnosis and management of rheumatoid arthritis.

Anti-CCP blood tests are commonly used in the diagnosis and monitoring of rheumatoid arthritis. They help differentiate RA from other forms of arthritis and assist in determining the severity and prognosis of the disease. These tests are typically performed alongside other diagnostic tests, such as the rheumatoid factor (RF) test and imaging studies, to form a comprehensive evaluation.
Why to Get Tested:
- To Diagnosing rheumatoid arthritis
- To Estimating disease severity
When to get Tested:
You may need this test if you have symptoms of rheumatoid arthritis. These include:
You may also need this test if other tests couldn’t confirm or rule out a diagnosis of rheumatoid arthritis.
Test Preparation:
No Need any Preparation for this test
Sample Required
2-3 ml Blood in SST or Yellow cap Tube
REJECT DUE TO
| Gross hemolysis | Reject |
| Gross lipemia | Reject |
| Gross icterus | OK |
| Heat-treated specimen | Reject |
Normal Values:
- <20.0 U (negative)
- 20.0-39.9 U (weak positive)
- 40.0-59.9 U (positive)
- > or =60.0 U (strong positive)
Reference values apply to all ages.
Negative Result Mean:
Negative CCP antibodies and negative RF, it means you are less likely to have rheumatoid arthritis. Your provider may need to do more tests to help find out what is causing your symptoms.
Positive Result Mean:
- Positive CCP antibodies and positive RF, it likely means that you have rheumatoid arthritis.
- Positive CCP antibodies and negative RF, it may mean you are in the early stages of rheumatoid arthritis or will develop it in the future.
