What percentage of RA patients are seronegative?
An estimated 20-25% of cases of RA are seronegative, meaning that patients do not express RF or ACPA in the serum despite meeting clinical classification criteria for RA. Furthermore, an estimated 50% of patients are seronegative in early disease and become seropositive (2).Nov 1, 2020
Is seronegative rheumatoid arthritis less severe?
