What's rheumatoid factor?
A doctor has provided 1 answer
A protein in blood: Rheumatoid factor is a protein-igm- directed against another protein- igg in the blood and is seen in high frequency(>80%) of patients with rheumatoid arthritis. It is not specific for R.A. As it may be seen in other disease states a high concentration of rhuematoid factor is highly suspicious for the disease but it has to fit the patient's complaints and physical findings.
