Novel Markers for Rheumatoid Arthritis, Anti-CarP, Anti-Sa, and Anti-CEP1, Are More Frequently Positive and Higher in Titer in RA Patients with Higher Vectra® Disease Activity Scores

February 21, 2024

Autoantibodies against citrullinated and carbamylated proteins in RA patients may be associated with more active disease and higher risk of developing joint erosions, and Vectra® is a blood test that yields a RA disease activity (DA) score from 1 to 100 that is low, moderate or high. In this abstract, 120 patient samples were analyzed to assess the relationship of DA as measured by Vectra® Score and the presence of novel autoantibody markers with potential prognostic value.
