Rheumatoid Factor (IgG) details
What Rheumatoid Factor (IgG) shows
Rheumatoid factor (RF) is an autoantibody that reacts against part of your own antibodies. Standard RF tests mainly detect the IgM type, while this test measures the IgG type specifically. It may be used to add information when evaluating rheumatoid arthritis or related inflammatory conditions, particularly when other results are unclear. A positive IgG RF result can be seen in rheumatoid arthritis and some other autoimmune conditions, and has been studied as a possible marker of disease activity. It can also occur in other conditions and in some healthy people, so it is not used alone and is interpreted with standard RF, anti-CCP antibodies and your symptoms.
