IMTEC-RA33-Antibodies is an indirect solid-phase enzyme immunoassay (ELISA) for the quantitative measurement of IgG class autoantibodies against RA33 (hnRNP A2) in human serum. The assay is intended for in vitro diagnostic use only as an aid in the diagnosis of early rheumatoid arthritis.

An isolated occurrence of anti-RA33 antibodies is considered as marker for rheumatoid arthritis (RA), but its diagnostic sensitivity depends on the population monitored. These antibodies occur independently from rheumatoid factors (RF) and their frequency in RF-negative RA (about 45%) is important for the diagnosis of early stages of RA.
