I have resently got test results from my doctor after first having a positive ANA result. According to them I have a positive anti-RNP antibody result. Does anyone know what this is and what is means, I can't seem to find much information on it. Please help, Im getting more and more worried.
Test: anti-RNP - Antibody to the Ribonucleoprotein
What test is for: The RNP antigen is similar to the Smith antigen, but has a different job in the cell.
What a positive test means: A positive test occurs in some patients with lupus but also in other related diseases. It helps to classify a patient but it is not usually useful to make a specific diagnosis nor to follow for worsening or recovery.
