Prenatal Tarama Test Parametreleri Plasental Lokalizasyon Yada Fetal Cinsiyetten Etkilenebilir

Aim: This study aims to investigate the relationship between first and second trimester screening test parameters and placental location together with fetal gender. Material and Methods: Fetal nuchal translucency (NT) measurement and maternal serum free beta human chorionic gonadotropin (b-HCG) and pregnancy-associated plasma protein-A (PAPP-A) values in the first trimester and maternal serum alpha-fetoprotein (AFP), human chorionic gonadotropin (hCG) and unconjugated estriol (uE3) levels in the second trimester were determined and compared to fetal gender and placental location for demonstrating the relationship between them. Results: NT values were higher among female fetuses (p= 0.04). AFP values were signifi-cantly higher in the posterior placenta group (p= 0.04), and first trimester hCG values were higher in the posterior placenta group with a borderline level of significance (p = 0.05). Conclusion: First and second trimester screening test parameters can be affected by fetal gender and placental location.
