Rheumatoid arthritis is often a quite difficult disease to diagnose since there are many conditions which could be responsible for causing the inflammation and joint stiffness. This means that there is no one definitive test for this condition.
Specific blood tests are often used for diagnosis but these aren’t always accurate for everyone. For example an antibody test that is known as anti-CCP (anti-cyclic citrullinated peptide) is available (http://www.elisakits...i-ccp-elisa-kit). However, people who test positive for anti-CCP are known to be highly likely to develop rheumatoid arthritis, but not everyone who has rheumatoid arthritis displays this antibody.
Also, approx. half of individuals with rheumatoid arthritis have a positive rheumatoid factor present in their blood at the start of the disease, however, this is made harder by the fact that one in 20 people without rheumatoid arthritis also tests positive.
In general, it is widely accepted that anybody who has a positive test for both anti-CCP and rheumatoid factor are more likely to have severe rheumatoid arthritis which will need high level of treatment.
