Limitations
The presence of antiribosomal P antibodies is not exclusively indicative of systemic lupus erythematosus (SLE) and may be found in a smaller percentage of patients without this condition. Moreover, positive results should be interpreted cautiously in the context of clinical findings and other laboratory tests due to the potential for false positives or varying antibody levels based on disease activity.
