Risks can be derived from maternal history and any combinations of biomarkers. Useful biomarkers at 11+0 to 13+6 weeks are mean arterial pressure (MAP), uterine artery PI (UTPI) or ophthalmic artery PSV ratio (OA-PSV) and serum PLGF (placental growth factor). Useful biomarkers at 19+0 to 23+6 weeks are MAP, UTPI or OA-PSV, estimated fetal weight, PLGF and sFLT-1. Useful markers at 35+0 to 36+6 weeks are MAP, UTPI or OA-PSV, PLGF and sFLT-1. The values of biochemical markers 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.
