🧪 Rheumatoid Factor (RF) — A Key Autoimmune Marker

Rheumatoid Factor (RF) is an antibody that can be present in the blood of individuals with certain autoimmune conditions, most notably Rheumatoid Arthritis (RA). An elevated RF level can suggest that your immune system is mistakenly attacking your body’s own tissues.

High RF levels may indicate:

• Rheumatoid Arthritis (especially when symptoms are present)

• Other autoimmune diseases (e.g., lupus, Sjögren’s syndrome)

• Chronic infections (e.g., hepatitis, tuberculosis)

• In rare cases, healthy individuals (especially with age)

While RF is not solely diagnostic, it’s often part of a broader autoimmune panel that includes ANA, ESR, and CRP to evaluate inflammation and immune system activity.
