DIAGNOSIS

ACPA epitopes — what are we actually looking at?

The use of assays to detect anti-citrullinated protein antibodies (ACPAs) is helpful in the diagnosis of rheumatoid arthritis. But how good are these assays at detecting ACPAs and do we really know what the results are telling us about ACPA specificity?
