RF can be positive in conditions other than rheumatoid arthritis.
Rheumatoid Factor (rf) is a laboratory blood test. It is commonly used as a arthritis support. The test looks for RF autoantibodies.
Doctors may also include it in diagnosis support assessments. The result should be read with the laboratory range, symptoms, medical history and other relevant results. The listed sample type is Blood (Serum).
A routine blood draw is low risk. You may feel a brief sting when the needle goes in, and some people notice temporary bruising, soreness or light-headedness afterwards. Fainting and infection are uncommon. The sample is collected at your home by a trained phlebotomist using sterile equipment, and the draw takes only a few minutes. If you feel unwell during or after collection, tell the phlebotomist or speak to your doctor.
