Rule-in and rule-out of pre-eclampsia using DELFIA Xpress PlGF 1-2-3 and sFlt-1: PlGF ratio

The objective of this study was to explore and validate thresholds for Placental growth factor (PlGF) and soluble fms-like tyrosine-kinase 1 (s-Flt-1) (as s-Flt-1: PlGF ratio), to rule-in and rule-out disease in women with suspected pre-eclampsia, using DELFIA® Xpress PlGF1-2-3 and sFlt-1 assays.

Understanding Fetal Fraction in cfDNA screening

Fetal fraction has been used by some laboratories to determine if they can have confidence in their results. However, there are significant factors to consider when determining its merit, including assay precision, the accuracy of a reported fetal fraction metric and the implications of using a fetal fraction cutoff. In the enclosed publication, we present the science, the data and the impact of using the fetal fraction metric within a clinical context.
