User avatar Hi Daisymaud,
This is a question that only your doctor can answer for you. I am giving you a list of things that can cause an abnormal RA factor, but I stress you must check with your doctor to rule these out.

A positive test may indicate:

Chronic hepatitis
Chronic viral infection
Infectious mononucleosis
Rheumatoid arthritis
Systemic lupus erythematosus
