Which tests are included in a rheumatoid panel?

• A. CBC, ESR, CCP antibody
• B. CBC, ESR, RF
• C. CBC, CMP, CCP antibody
• D. CBC, ESR, ANA

Answer: (A)

A rheumatoid panel aims to combine a picture of overall inflammation with a test that is highly specific for rheumatoid arthritis. A CBC provides general blood-count information, including anemia of chronic disease and platelet changes that often accompany inflammation. ESR measures systemic inflammation and tends to be elevated during active RA, helping gauge activity. The CCP antibody test detects autoantibodies highly specific for rheumatoid arthritis; a positive CCP strongly supports RA and can indicate a more aggressive disease course, even if RF is negative. RF is another RA-associated antibody but is less specific and can be positive in other conditions or in healthy people, so it’s not as definitive for confirming RA. ANA and CMP don’t target RA-specific processes, making them less appropriate for a focused RA panel.
