Diagnosis of preeclampsia with soluble Fms–like tyrosine kinase 1/placental growth factor ratio: an inter–assay comparison

The angiogenic factor ratio soluble Fms–kinase 1 (sFlt–1)/placental growth factor (PlGF) is a novel diagnostic tool for preeclampsia. We compared the efficacy of the KRYPTOR (BRAHMS) automated assays for sFlt–1 and PlGF with the Elecsys (Roche) assays in a routine clinical setting. Preeclamptic women (n = 39) were included shortly after the time of diagnosis. Normotensive control pregnancies were matched by gestational age (n = 76). The KRYPTOR...
