What is the one definitive test to diagnose rheumatoid arthritis?
One test is not definitive
A positive rheumatoid factor (RF)
An elevated erythrocyte sedimentation rate (ESR)
A positive antinuclear antibody (ANA)
The Correct Answer is A
A. While tests like RF, ESR, and ANA can indicate the presence of rheumatoid arthritis or autoimmune activity, no single test is definitive for diagnosing RA.
B. A positive rheumatoid factor is common in RA but can also be found in other conditions, making it not exclusively diagnostic.
C. An elevated ESR indicates inflammation but is nonspecific and not solely indicative of rheumatoid arthritis.
D. A positive ANA is associated with various autoimmune diseases and is not specific to RA.
