How do I read my rheumatoid arthritis blood test results?

A level above 20 suggests the possibility of RA. As with rheumatoid factor, some people with positive anti-CCP antibody will not have RA, but this test is somewhat more specific for RA than the rheumatoid factor. The higher the levels of anti-CCP antibody, the more likely it is to suggest RA.

Does all types of arthritis show up in blood tests?

Blood tests are not needed to diagnose all types of arthritis, but they help to confirm or exclude some forms of inflammatory arthritis. Your doctor may also draw joint fluid or do a skin or muscle biopsy to help diagnose certain forms of arthritis. Making an arthritis diagnosis may take some time.
