AVISE® CTD Test Report

AVISE® Lupus Result : Negative – Index: -5.0

A result is marked as equivocal when one or more critical values is close to a threshold that would significantly change the index value if the threshold was crossed.

The output of the AVISE® Lupus out put algorythem:
Tier 1 index helps identify patients that have highly
elevated or positive SLE associated analytes

Tier 1 Analytes: 4 analytes that are associated with first
step of the AVISE® Lupus analysis. Associated with
SLE with a high degree ofspecificity

A tier 1 positive is triggered if:

  • Anti-Sm is > 10 U/mL
  • EC4d is > 75 Net MFI
  • BC4d is > 200 Net MFI
  • Anti-dsDNA is > 301 U/ml and is also
    confirmed by Crithidia
