Nothing terrifies nephrologists quite like the consult from labor and delivery. And one of the most vexing questions is, “Is this preeclampsia, proteinuric CKD, or a lupus flare?”
Perhaps a newly approved blood test will be able to shed light on this clinical conundrum. The ratio of soluble fms-like tyrosine kinase 1 (sFlt-1) to placental growth factor (PlGF) has appeared predictive of severe preeclampsia. The PRAECIS trial evaluated this in a prospective manner.
