Elevated anti-RNP antibodies are characteristic of mixed connective tissue disease (MCTD). They can also be present in SLE and other connective tissue diseases.
Low values may indicate
Negative or low levels indicate no significant anti-RNP antibody activity.
Frequently asked questions
- What is a normal RNP Antibodies level?
- A typical reference range for RNP Antibodies is 0–0.9 AI (source: ABIM). Reference ranges vary by laboratory, age, and sex, so always compare against the range on your own lab report.
- What units is RNP Antibodies measured in?
- RNP Antibodies is most commonly reported in AI. Labs in different countries may use other units — you can convert between them with BloodId's blood test unit converter.
- Where do RNP Antibodies reference ranges come from?
- BloodId uses ABIM standard reference ranges and educational information from MedlinePlus (see our methodology). Reference ranges still vary by lab, age, and sex, so always compare against your own report.
- Can I track RNP Antibodies over time?
- Yes. Upload results from any lab and BloodId charts your RNP Antibodies over time against its reference range, so you can see whether the trend is rising, falling, or stable.
