Test Description: Rheumatoid Factor (RA Factor) – Qualitative

The Rheumatoid Factor (RA Factor) – Qualitative test detects the presence or absence of rheumatoid factor antibodies in the blood. These antibodies are commonly found in individuals with rheumatoid arthritis (RA), an autoimmune disease that causes joint inflammation and damage. The qualitative test provides a simple positive or negative result, indicating whether rheumatoid factor is present. While a positive RA factor test can suggest rheumatoid arthritis, it is not definitive, as RA factor can also be found in other conditions such as lupus, chronic infections, or even in healthy individuals. Further testing and clinical evaluation are typically required for a conclusive diagnosis.
