Objective: Rheumatoid factor (RF) and anti‐cyclic citrullinated peptide antibody (anti‐CCP) are commonly used for diagnosis of rheumatoid arthritis (RA), although other rheumatic diseases with arthritis can test positive. This study aimed to determine the cutoff values for RF and anti‐CCP with the b...
