About Pre-eclampsia

Most women have a normal pregnancy without complications. However, pre-eclampsia is a relatively common, yet serious complication, affecting between two and eight out of every 100 pregnancies, that may develop during pregnancy (at any time after 20 weeks of pregnancy) and up to six weeks after delivery. It can affect both the pregnant woman and her unborn baby. If the risk for preterm pre-eclampsia is detected in time, the development of the condition can be monitored and prevented.6,7,8
It is important to get screened for the risk of pre-eclampsia as early as possible in the pregnancy to allow adequate time for the doctor managing the pregnancy to ensure that treatment4,7,9 is started at the right time.
You can find out your risk of developing pre-eclampsia between 11 and 14 weeks of pregnancy.6,7 Pre-eclampsia screening is needed to determine if you are at high risk for pre-eclampsia. The screening includes a blood test, a blood pressure measurement, and, if available, an ultrasound. Screening for the risk of pre-eclampsia is an important step you can take to protect your health and that of your baby.

Pre-eclampsia FAQs

The test tells you if your pregnancy needs to be monitored more closely and a treatment to be initiated.

Screening for pre-eclampsia is done in the first trimester, preferably between 11 and 13+6 weeks of pregnancy. It includes a simple blood test and your blood pressure is measured. It may also include an ultrasound. In addition health and pregnancy history is needed.

Your risk of developing pre-eclampsia is calculated from the results of simple exams (blood test, blood pressure and ultrasound) and medical information. Based on the calculation results your doctor will adapt your pregnancy management and may suggest preventive care.

If the test result indicates a high risk for preterm pre-eclampsia, research has shown that prophylactic low-dose aspirin treatment may be effective to reduce the onset of pre-eclampsia4,6,7,8; however, because not all women respond the same to aspirin4,9, aspirin intake during pregnancy should only occur after consultation with and advice from your physician/obstetrician.

After 16 weeks of pregnancy, it may be too late to start preventative treatment4,8, but you can still be tested to know your risk of developing the condition. Such information will allow you to discuss options with your doctor.
