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.
