Biochemical screening for the prediction of pre-eclampsia.
J Pak Med Assoc Jan ;55(2):79-82.

Preeclampsia has long been a disease with an unknown etiology. Various studies have been conducted to decipher the factors involved and this has lead to the development of a few theories. From history, it comes that uterine distension and even fetus have been thought to be the probable contributors. Since it was found that preeclampsia can occur with abdominal ectopic pregnancies without increased uterine size and is more common in pregnancies without a fetus [hydatidiform mole], this eliminated these two possibilities. The placenta is necessary for preeclampsia but all pregnant women have placentas and only 5% become preeclamptic. This is a review article.
