Analysis of the Effectiveness of First Trimester Nucal Translucence, Free Beta-Human Chorionic Gonadotropin, and Pregnancy-Related Plasma Protein-A in Prediction of Pregnancy Complications

Abstract

In this study, we aimed to investigate whether there was an association between fetal nuchal translucency (NT) and the serum markers plasma protein-A (PAPP-A) and free beta-human chorionic gonadotropin (β-hCG) measured by the first-trimester screening test, as well as birth weight and hypertension. 454 pregnant women who had undergone the first-trimester screening test for Down syndrome were included in the study. All measurements and values of NT, PAPP-A and β-hCG levels were performed between gestational weeks 11-14. Values of PAPP-A and β-hCG converted to multiples of the corrected median (MoM) were obtained using the PRISCA software package. Regarding the prediction of SGA infants, when the PAPP-A value
