A system for monitoring a fetus in a pregnant woman, and/or the maternal health risk for pregnancies complicated by such as pre-eclampsia and hypertensive disorders is configured to be worn by the pregnant woman, preferably so as to allow monitoring during daily life, e.g. in the form of an adhesive patch. The unit has a sound sensor, e.g. a microphone or accelerometer, to be positioned on the skin of the abdominal area so as to detect a vascular sound from umbilical arteries of the fetus or from the uterine arteries of the pregnant woman. The sound sensor is functionally connected to a processing unit which executes a processing algorithm on the captured vascular sound and extracts a signal parameter accordingly. The processing unit then communicates the signal parameter, e.g. using an audio signal, a visual display or by means of a wired or a wireless data signal.

The invention provides serum-based, diagnostic, biological assays for predicting disorders of pregnancy resulting from poor trophoblast and/or placental ischemia, including preeclampsia. Serum samples from such subjects exhibit an ability to disrupt the architecture involving fetal trophoblasts and maternal endothelial cells in a three-dimensional, dual cell co-culture system provided herein, in contrast to normal pregnancy serum samples. Based on these distinctions, the assays are employed to predict pregnancy outcomes as early as first trimester.

The present invention relates to a method for determining the risk of a pregnant woman developing pre-eclampsia. The method comprises i) determining the level of one or more biochemical markers in a sample obtained from a pregnant woman, and ii) comparing the level of the at least one biochemical marker in the sample with the level of the same biochemical marker in a control sample. A difference in the level of the biochemical marker in the sample relative to the control sample is indicative of an increased risk of developing pre-eclampsia. The isoform biochemical markers are preferably P1GF-2 and P1GF-3. The present invention relates also to a method for determining whether a pregnant woman has pre-eclampsia and as well as a kit for assessing the risk or presence of pre-eclampsia. In addition, the invention relates also to a computer program used in these determinations.
