RA FACTOR

The RA factor test, or rheumatoid factor test, is a blood test used to help diagnose rheumatoid arthritis and other autoimmune diseases. It measures the presence of rheumatoid factor antibodies, which can indicate inflammation and the immune system's response. A positive result may suggest rheumatoid arthritis, but it is not definitive, as these antibodies can occur in other diseases and even in healthy individuals. The test is usually part of a broader evaluation that includes clinical examination and other diagnostic tests. Despite its limitations, the RA factor test is a valuable tool in the diagnostic process for autoimmune conditions.
