Arthritis is an inflammatory disorder that affects one or more joints. There are several different conditions that can affect the joints and other connective tissues. These include osteoarthritis, rheumatoid arthritis, SLE (systemic lupus erythematosus), and more. If you are concerned about rheumatoid arthritis, other autoimmune diseases, or other inflammatory conditions, this panel can be a good starting point.  The Arthritis Screening Panel includes Rheumatoid Factor, Antinuclear Antibodies, and C‐Reactive Protein (High Sensitivity). It also includes a Complete Blood Count (CBC) and a Comprehensive Metabolic Panel (CMP), which are often ordered in an annual physical examination and can be used to monitor a variety of conditions.
