Antibodies to RNP occur in approximately 50% of patients with lupus erythematosus (LE) and in patients with other connective tissue diseases, notably mixed connective tissue disease (MCTD). Both of these techniques require the precipitation of antigens for valid results. However, sometimes, for often unknown reasons, the immune system starts producing a new type of special proteins called autoantibodies. Basic metabolic panel.

It may also be seen in those taking drugs such as procainamide and hydralazine, though it is not usually tested or monitored under these conditions. The ANA antibodies that bind to these ENAs are called anti-ENAs. A high level of anti-dsDNA in the blood is strongly associated with lupus and is often significantly increased during or just prior to a flare-up. On anti-nuclear antibody tests, these antigens have a speckled pattern.[8]. Objectives To describe the immunological pattern of SLE patients through investigating specific antinuclear autoantibodies by enzyme dot immunoassay and studying their frequency in both positive I'm a little freaked out. [1], An extractable nuclear antigen panel, or an ENA panel, tests for presence of autoantibodies in the blood that react with proteins in the cell nucleus. There are different types of this disorder.
