Pre-eclampsia Screening and Management

Pre-eclampsia is a complication of pregnancy marked by high blood pressure and presence of protein in the urine (proteinuria). 

Pre-eclampsia is affecting between two and eight out of every 100 pregnant women. The exact cause is unknown, but its risks are clear: left untreated, pre-eclampsia can cause growth-restriction or preterm birth of the child, and in some cases, lead to maternal and perinatal mortality. But with screening, the high risk of the more severe forms of pre-eclampsia, early-onset and preterm pre-eclampsia, can be predicted and prevented.

The Combined Screening Program – the first step to better detection

When it comes to effectively predicting pre-eclampsia, the combined screening program outperforms screening methods that rely only on maternal history. The effectiveness of preeclampsia screening also depends on marker combination[i].

A combined screening program for pre-eclampsia is recommended by international guidelines[ii, iii] to identify women at high risk of pre-eclampsia in the early stages of pregnancy. The combined screening program consists of the PlGF 1-2-3™ blood test, maternal medical history assessment, mean arterial blood pressure measurement and, if available, uterine artery Doppler ultrasonography.

During second and third trimesters, sFlt-1 (soluble Fms-like tyrosine kinase-1) and PlGF are both predictive and diagnostic for pre-eclampsia. It has been shown that increased levels of sFlt-1 and decreased levels of PlGF in maternal serum can predict the subsequent onset of pre-eclampsia[iv, v].

Management solutions for Prenatal Screening

PerkinElmer supplies the LifeCycle™ software which enables monitoring of pre-eclampsia status with the sFlt-1/PlGF ratio. The ratio results can be linked to the same patients’ other results in LifeCycle™software. For ratio calculations, the cut-offs for pre-eclampsia management are adjustable.
