Renown Rheumatology's Comprehensive Approach to Rheumatic Diseases
The board-certified rheumatologists at Renown Rheumatology provide state-of-the art care for a wide range of autoimmune rheumatic diseases such as rheumatoid arthritis, psoriatic arthritis, lupus, Sjogren syndrome, vasculitis, gout, and many more. We use the most advanced evidence-based diagnostic and therapeutic measures to restore health and enhance well-being.
Common Diagnostic Studies Used in the Evaluation of Rheumatic Diseases
- RF (Rheumatoid Factor): Confers nonspecific risk of rheumatoid arthritis.
- ACPA (Anti-Citrullinated Protein Antibody): Confers specific risk of rheumatoid arthritis.
- ANA (Anti-Nuclear Antibody): Confers nonspecific risk of connective tissue disease.
- ANCA (Anti-Neutrophil Cytoplasmic Antibody): Confers risk of small vessel vasculitis.
- APLA (Anti-Phospholipid Antibody): Confers risk of antiphospholipid syndrome.
- C3 and C4 (Complement proteins 3 and 4): Low levels suggest active disease in lupus or related autoimmune diseases.
- UPCR (Urine Protein-to-Creatinine Ratio): High levels suggest active lupus nephritis or small vessel vasculitis.
- Uric acid: Elevated in people with gout but may be low during acute gout attack.
- ESR (Erythrocyte Sedimentation Rate): Nonspecific indicator of chronic inflammation.
- CRP (C-Reactive Protein): Nonspecific indicator of acute inflammation.
- CBC (Complete Blood Count): Used to assess the effects of autoimmune diseases and immunosuppressive medications on bone marrow function.
- CMP (Complete Metabolic Profile): Used to assess the effects of autoimmune diseases and immunosuppressive medications on kidney and liver functions.
- HLA-B27 (Human Leukocyte Antigen B27): Confers risk of spondyloarthropathy.
- HLA-B51 (Human Leukocyte Antigen B51): Confers risk of Behcet’s disease.
- Musculoskeletal Ultrasound: Used at point of care to assess joint inflammation, guide joint injection or joint fluid aspiration.
- XR: Used to assess joint damage from inflammation or wearing over time.
- CT or MRI: Used to assess joint, muscle, and blood vessel inflammation which are not visualizable on plain XR.
- Synovial Fluid Cytology: Used to test for crystals and blood cells in inflamed joints.
- Synovial Fluid Gram Stain and Culture: Used to test for infection in inflamed joints.
