PP13 and Doppler Study to Predict Preeclampsia

Assessment of biochemical and sonographic marker to predict the risk for developing preeclampsia Among biochemical markers are serum level of Placental Protein 13 (PP13) and Placenta Growth factor (PIGF). For sonographic marker Doppler pulsatility Index of the blood flow through the uterine maternal arteries is assessed. PP13 is produced by the placenta and released to the maternal blood circulation. It has been shown to be an effective serum marker for early onset preeclampsia (Nicolaides KH et al., 2005). The purpose of this study is to combined the assessment of the biochemical markers with Doppler in the first and the second trimester to provide a comprehensive evaluation of various methods for sequential and combined analysis to assess the risk for developing preeclampsia.
