    Here is some information on diagnosing RA -- because no single test can clearly identify RA, doctors diagnose it based on factors strongly associated with the disease. There are a number of blood tests your doctor may order to try to determine if you have RA, and each has its limitations. Here is an overview of some of the more common tests and their limitations. Here is some additional information that you might find helpful :

    "Rheumatoid factors are a variety of antibodies that are present in 70% to 90% of people with rheumatoid arthritis (RA). Rheumatoid factor (RF), however, can be found in people without RA or with other autoimmune disorders. In general, when no rheumatoid factor is present in someone with RA, the course of the disease is less severe."

    Best wishes,
