Official Title: Second Trimester Maternal Serum Homocysteine Levels and Uterine Artery Doppler for Prediction of Preeclampsia and Poor Placentation Disorders
Brief Summary: The current study included the singleton pregnancies (without history of previous risk factors), had their homocysteine measured as part of a serum-screening program in addition to uterine artery Doppler. Sensitivity, specificity, positive and negative predictive values, for development of preeclampsia and other adverse pregnancy outcomes were assessed as follows; (1) Homocysteine cutoff level at 6.3 µmol/l; (2) Bilateral notches on Doppler with a mean RI >0.5, all unilateral notches with a mean RI >0.6, in addition, absence of notches with a mean RI >0.7; (3) Doppler assessment combined with the homocysteine cutoff (6.3 µmol/l).
