A member asked:

What are the distinctions between rheumatoid factor test and ana test?

A doctor has provided 1 answer

See below: Both are autoimmune tests used to screen for autoimmune disease. A rheumatoid factor is used to screen for rheumatoid arthritis and ANA or antinuclear antibody test is used to screen for ana-associated autoimmune diseases such as lupus.
