Diagnosis of preeclampsia and fetal growth restriction with the sFlt-1/PlGF ratio: Diagnostic accuracy of the automated immunoassay Kryptor®

Longitudinal reference ranges of the sFlt-1 and PlGF level in healthy pregnancies were in line with those levels measured with other immunoassays. Comparison of the sFlt-1/PlGF ratio between PE-related outcomes including FGR or PE and healthy controls showed a high diagnostic accuracy with an area under the curve (AUC) of 0.917 for PE-related outcomes and 0.919 for PE.
