What is Seropositive RA?

Seropositive simply means that your rheumatoid factor blood test is positive. Some also count the anti-CCP positive test as seropositive.  In general, patients develop positive rheumatoid factor within one year of developing symptoms.  Overall, patients who are seropositive have a more severe disease course with more joint deformities, x-ray damage, disability and inflammation outside of the joints.  However, there are many exceptions to these rules.
