What is this test?

Rheumatoid factor (RF) is used in the diagnosis of rheumatoid arthritis (RA). RF results are positive in approximately 75% of patients with RA, although RF is not etiologically related to RA. High RF titers indicate a poorer prognosis, as patients with higher RF levels tend to have more severe disease.
