Use and utility of serologic tests for rheumatoid arthritis in primary care.

CONCLUSIONS: ACPA has a higher PPV for RA than IgM RF, whereas their NPV is identical. ACPA is the better choice when testing for RA in primary care. Seroconversion is rare, and it is only rarely relevant to retest. FUNDING: The Department of Clinical immunology at Odense University Hospital funded the study. TRIAL REGISTRATION: not relevant.
