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.
