Preeclampsia Screening and Monitoring

What is Preeclampsia?

Preeclampsia is a serious pregnancy complication affecting 2-8% of pregnant women worldwide. Preeclampsia is traditionally diagnosed based on high blood pressure and presence of protein in urine after the 20th week of gestation. Symptoms include headache, blurred vision, nausea, vomiting and leg swelling.

This disorder is thought to be caused by poor function of the placenta, which leads to its inability to support the adequate blood supply required by the fetus, and poor uterine arterial vasodilatation, attributing to the common symptoms of preeclampsia.

Why Screening?

Preeclampsia is a major cause of morbidity and mortality for both the mother and fetus. Currently, research suggested that through screening and early risk assessment, preventive measures could be instigated to reduce the risk of preeclampsia development.

Our screening follows the newest guidelines set by the International Federation of Gynecology and Obstetrics (FIGO) in 2019 and is evidenced to be in line with the global standards for first-trimester preeclampsia screening.

Who is Eligible?

All women with a singleton pregnancy between their 11+0-13+6 weeks of gestation.

Screening Process

  1. Record obstetric and medical history
  2. Take blood sample
  3. Measure blood pressure twice in both arms
  4. Ultrasound scan to measure uterine artery blood flow

After Screening

The result of estimated risk of preterm preeclampsia will be available in approximately 3 working days.

If you are screened high risk for preeclampsia, you will be invited to attend a follow up visit for further counselling.
