What does the RF test evaluate in patients?

The RF test, or rheumatoid factor test, is specifically designed to evaluate the presence of rheumatoid factor in the blood, which can be an indicator of rheumatoid arthritis. In patients with rheumatoid arthritis, the immune system mistakenly produces antibodies (called rheumatoid factors) that attack the body's own tissues, particularly affecting the joints. A positive RF test suggests that inflammation may be present, supporting the diagnosis of rheumatoid arthritis or assisting in evaluating the severity of the disease. Thus, this test is integral in confirming or ruling out this specific type of autoimmune condition.

While the other options deal with various health concerns, they are not related to the RF test. For example, testing for H. Pylori involves different methods to check for gastric infections, cardiovascular disease risk assessment generally involves cholesterol and blood pressure measurements, and HIV testing is centered around different markers in the blood altogether.
