SLICC 2012 SLE classification (Petri Table 3)

SLICC 2012 SLE classification (Petri Table 3). classified iff biopsy-proven lupus nephritis plus ANA or anti-dsDNA, or at least four criteria including at least one clinical and one immunologic. 11 clinical and 6 immunologic caller flags. Direct Coombs counts only in the absence of hemolytic anemia. Criteria need not be concurrent. Not a diagnosis. Not 1997 ACR. Not 2019 EULAR/ACR. magent does not examine skin, assay serologies, or read a biopsy.
