How accurate are blood tests in diagnosing arthritis?

It all depends. Lab tests are used to confirm what the history and physical exam suggest. Many forms of arthritis cannot be diagnosed with blood tests. Blood tests are most helpful when they are relatively specific for one type of arthritis, for example the ccp antibody in ra.
