The RAdx5™ is a novel comprehensive diagnostic and prognostic panel for rheumatoid arthritis available exclusively at RDL. It combines 3 novel markers (14-3-3n, anti-CEP-1 and anti-Sa) with 2 traditional markers (anti-CCP and RF-IgM) to not only enhance the diagnosis of RA in early or established disease, but also to help predict disease severity. If 14-3-3n and/or anti-Sa positivity is present, the disappearance or decrease of these antibodies with treatment is associated with less radiographic progression. In pre-clinical RA, positivity of anti-CEP-1 along with anti-CCP antibodies significantly raises the risk of imminently developing clinical RA.
