Summary
There is a growing body of evidence that PlGF-based testing improves
diagnosis and reduces adverse maternal outcomes in the assessment of
suspected preterm pre-eclampsia, by appropriate risk stratification and
resource redistribution. The Triage PlGF test and Elecsys sFlt-1/PlGF
ratio are both recommended by the National Institute for Health and Care
Excellence but are not interchangeable. Both assays have similar
predictive properties but also unique advantages and disadvantages. The
test to be implemented needs to be carefully chosen for the setting with
involvement from all relevant parties.
