Final answer:
Not all persons affected with rheumatoid arthritis have the presence of the rheumatoid factor (RF) which forms immune complexes. The statement that all persons affected with rheumatoid arthritis have the presence of the rheumatoid factor is false.
Step-by-step explanation:
False
Not all persons affected with rheumatoid arthritis have the presence of the rheumatoid factor (RF), an autoantibody that reacts with a fragment of immunoglobulin G to form immune complexes. While RF is present in the majority of individuals with rheumatoid arthritis, it is not universally present. Therefore, the statement that all persons affected with rheumatoid arthritis have the presence of the rheumatoid factor is false.
