One test is not definitive
A positive rheumatoid factor (RF)

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.
