This screening test is done during the first trimester (11 to 14 weeks) to identify if you are at high risk of developing pre-eclampsia particularly before 37 weeks gestation. This is pregnancy induced high blood pressure and occurs in around 2 – 8% of pregnancies. It is one of the most common life threating conditions in pregnancy.
Identifying high risk of developing this condition could potentially improve your pregnancy outcome because better maternal and baby monitoring can lead to prevention of disease or earlier detection so you can be managed appropriately.
This screening test is usually done at the same time with the screening test for Down’s.
