Abstract
This study was designed in a prospective manner to search for the prediction of preeclampsia at an early stage in pregnancy allows categorization and management of these cases as high risk, which could hopefully improve both maternal and fetal outcomes.
First we aim to assess the predictive value of elevated serum NG Hydroxy-L-Arginine in pregnant women with abnormal uterine artery Doppler wave forms who later develop preeclampsia in the course of their current pregnancies.
Second we also aim to that the measurement of serum NG Hydroxy-L-Argininecan categorize the potential preeclamptic cases into mild and sever before the development of the clinical condition.
The study population was 100 pregnant women divided into two, group I 50 pregnant women with abnormal uterine artery Doppler waveform and 50 other pregnant women with normal uterine artery Doppler waveforms. Comparative study between the study groups show by using the (ROC) curve and the area it were used to estimate the diagnostic power of each continous test varriable and determine the sensitivity and specificity at different cut off points.
