The Rheumatoid Factor IgA Antibody Test measures IgA-class rheumatoid factor, an autoantibody linked to rheumatoid arthritis and other autoimmune diseases. Elevated levels may indicate joint inflammation, Sjögren’s syndrome, or chronic infections. Doctors use this blood test alongside other markers to confirm diagnosis, assess disease activity, and guide treatment decisions for patients with suspected autoimmune or inflammatory disorders.

The Rheumatoid Factor IgA IgG IgM Antibodies Test measures multiple rheumatoid factor classes to aid in diagnosing rheumatoid arthritis and related autoimmune diseases. Elevated levels may suggest joint inflammation, Sjögren’s syndrome, lupus, or chronic infections. Doctors use this comprehensive test to confirm autoimmune involvement, investigate persistent pain or stiffness, and guide treatment planning by assessing disease activity across antibody types.

The Rheumatoid Factor IgG Antibody Test measures IgG-class rheumatoid factor, an autoantibody often linked to rheumatoid arthritis and autoimmune diseases. Elevated levels may indicate joint inflammation, Sjögren’s syndrome, or chronic infection. Doctors use this test with other markers to confirm diagnosis, assess autoimmune activity, and guide treatment for patients with persistent joint pain, swelling, or suspected inflammatory disorders.

The Rheumatoid Factor IgM Antibody Test measures IgM rheumatoid factor, the most common autoantibody linked to rheumatoid arthritis. Elevated levels may indicate autoimmune activity, Sjögren’s syndrome, or chronic infections. Doctors use this test to help diagnose rheumatoid arthritis, investigate joint pain, swelling, or stiffness, and monitor disease progression. Results are often combined with other antibody tests for accurate evaluation and treatment planning.

The Rheumatoid Factor (RF) Test measures RF antibodies in blood to help diagnose rheumatoid arthritis and other autoimmune conditions. High RF levels may indicate rheumatoid arthritis, Sjögren’s syndrome, or other connective tissue diseases, though they can also appear in some infections. Doctors order this test to investigate joint pain, stiffness, or swelling. Results provide important insight into autoimmune activity, joint health, and inflammatory disease management.

Comprehensive autoimmune screening panel including ANA with reflex to titer and pattern, dsDNA, SS-A, SS-B, Scl-70, RNP, Sm antibodies, complement C3, C4, CH50, and Rheumatoid Factor. Designed to support evaluation of systemic autoimmune and connective tissue disorders with clinically relevant, disease-specific biomarkers.

The Rheumatoid Arthritis - Advanced Panel is a comprehensive set of tests specifically curated for a detailed evaluation of rheumatoid arthritis (RA) and other related autoimmune conditions. This panel not only aids in diagnosing RA but also in assessing the severity of the disease, monitoring treatment efficacy, and evaluating overall health and organ function. It is designed for those who exhibit symptoms of RA or for patients under treatment to monitor disease activity and manage treatment plans effectively.
