CCP : labtest

Why Get Tested?
To help diagnose rheumatoid arthritis (RA) and differentiate it from other types of arthritis; sometimes to help evaluate the prognosis of a patient with RA
When to Get Tested?
When a doctor suspects RA in a patient who has joint inflammation and/or undiagnosed or undifferentiated inflammatory arthritis, with symptoms that suggest but do not yet meet the criteria of RA
Sample Required?
A blood sample drawn from a vein in your arm

How is it used?
A CCP test may be ordered along with or following a Rheumatoid factor (RF) test to help diagnose Rheumatoid arthritis (RA). CCP may also be ordered to help evaluate the likely development of RA in patients with undifferentiated arthritis – those whose symptoms suggest but do not yet meet the ACR criteria for RA. According to American College of Rheumatology, approximately 95% of patients with a positive CCP will develop RA in the future.
