The rheumatoid factor (RF) test checks for an antibody that can be present in autoimmune conditions, especially rheumatoid arthritis. It is ordered when a person has joint pain, swelling, or stiffness that might be due to an autoimmune disease.
What it measures
- Rheumatoid factor (RF) — An antibody that may be elevated in rheumatoid arthritis and other conditions.
- RF titer — A measure of how much RF is present, reported as a number or dilution.
- Isotype (IgM, IgG, IgA) — Some tests specify which type of RF antibody is present.
Who it is for
A primary care doctor or rheumatologist typically orders this test when evaluating joint symptoms or suspected autoimmune disease.
Preparation
No fasting or special preparation is usually needed for the rheumatoid factor test.
Results and what they mean
Results are reported as a value with a reference range, often as negative or positive. A positive result does not confirm a diagnosis, and a negative result does not rule it out. Only a clinician can interpret your results in the context of your symptoms and other tests. This is general information, not medical advice.
Requesting the Rheumatoid Factor (RA) Test in Arizona
Order online, choose a certified collection site in Arizona, and review results through a secure portal. No referral is required, and orders are processed confidentially. Because the region is far-flung, long gaps between communities that reward planning a lab visit ahead of time — worth planning around when you book.
