This is a study for the evaluation of the benefits of 1 st Trimester risk markers in detecting Early Onset Pre-eclampsia and the use of the Placental Growth factor(PIGF) as a potential marker for Trisomy 21 and other aneuploidies.

Aim of this prospective nonprofit study is to analyze the benefits of early onset pre eclampsia risk assessment in the 1st trimester (measuring biochemical markers [PIGF], blood pressure and Doppler ultrasound), and how the results can permit to modify or influence the course of the preeclampsia during the pregnancy. The investigators will also evaluate the potential use of the PIGF as a marker to improve the prenatal screening with the currently used nuchal translucency, serum Pregnancy-associated plasma protein A (PAPP-A) and free beta subunit of human chorionic gonadotropin (fBhCG) parameters.

Primary Outcome Measures:
  • levels of Placental Protein 13 (PP13) , PIGF, PAPP-A, PIBF [ Time Frame: 6-13.6 wks gestation ] [ Designated as safety issue: No ]
    levels of PP13, PIGF, PAPP-A will de considered in association with Doppler ultrasound and standardised blood pressure measurements to see if they can be used as early risk markers in patients having a delivery before 34 weeks gestation
