Swedish researchers have developed a blood test that can predict the likelihood of developing rheumatoid arthritis.  The test measures cytokines and chemokines, which increase significantly in the years prior to the onset of rheumatoid arthritis.

People identified with the risk of developing the disease can receive early treatment and lead active lifestyles, which decreases the likelihood of joint damage that leads to joint replacement.

The findings appear in the recent issue of Arthritis & Rheumatism.
