Can a blood test predict rheumatoid arthritis?
While you can’t prevent rheumatoid arthritis, a recent study suggests that it may be possible to predict the onset of the disease through a simple blood test.

What tests can be done to detect arthritis?
X-rays of joints and surrounding tissues
What other blood tests are used to treat rheumatoid arthritis?
