Risk assessment

Risk for preeclampsia

Risks can be derived from maternal history and any combinations of biomarkers. Useful markers at 19-25 weeks are mean arterial pressure (MAP), uterine artery PI (UTPI), serum PLGF and sFLT-1.

The values for PLGF and sFLT-1 depend on maternal characteristics and reagents used for analysis and they therefore need to be converted into MoMs. In the application below you can either use the MoM values reported by the laboratory or provide the raw data and the MoM values will be calculated.

Please record the following information and then press Calculate.
