Question

List four diagnostic tests that you would expect to be positive for a patient with Rheumatoid Arthritis (RA).

Answer 1

The four diagnostic tests commonly used for diagnosing Rheumatoid Arthritis (RA) are RF test, Anti-CCP antibody test, CRP test, and ESR test.

Step-by-step explanation:

Rheumatoid arthritis (RA) is diagnosed through a combination of symptoms, imaging tests, and blood tests. Four diagnostic tests that are commonly used and expected to be positive in a patient with RA are:

1. RF (rheumatoid factor) test: This test detects the presence of antibodies known as rheumatoid factors in the blood. Rheumatoid factors are often found in people with RA.
2. Anti-CCP (anti-cyclic citrullinated peptide) antibody test: This test looks for antibodies that attack a specific protein called citrullinated peptide. High levels of anti-CCP antibodies are associated with RA.
3. CRP (C-reactive protein) test: This test measures the levels of a protein produced by the liver in response to inflammation. Elevated CRP levels can indicate inflammation in the body, which is common in RA.
4. ESR (erythrocyte sedimentation rate) test: This test measures how quickly red blood cells settle in a tube of blood. Faster settling rates can indicate inflammation, and high ESR levels can be a sign of RA.
