Smith Ab and Sm/RNP Ab Reference Ranges:
<20 Units Negative
20-39 Units Weak Positive
40-80 Units Moderate Positive
>80 Units Strong Positive

A positive Sm/RNP Ab result indicates the presence of antibodies reactive with the Smith (Sm) protein and/or ribonuclear protein (RNP). This Sm/RNP assay cannot distinguish between Anti-Sm and Anti-RNP activity, thus should be considered with the Sm Ab test result to determine clinical significance.
Components:
  • 2366 - SMITH AB
  • 2365 - SM/RNP AB
