Prenatal Screening Test Parameters Can Be Affected By Either Placental Location Or Fetal Gender

Öz

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.

Prenatal Tarama Test Parametreleri Plasental Lokalizasyon Yada Fetal Cinsiyetten Etkilenebilir

Öz

Amaç: Bu çalışma ilk trimester ve ikinci trimester tarama testi parametreleri ile plasental lokalizasyon ve fetal gender arasında ilşki olup olmadığını araştırmaktadır.Gereç ve Yöntemler: Fetal ense kalınlığı NT ölçümü ve ilk trimester maternal serum serbest beta human koryonik gonadotropin b-HCG , pregnancy-associated plasma pro-tein-A PAPP-A değerleri ile ikinci trimester maternal serum alfa-fetoprotein AFP , human koryonik gonadotropin hCG and ankonjuge estriol uE3 düzeyleri tesbit edildi ve fetal cinsiyet ve plasenta lokalizastonu ile ilişkisini göstermek için karşılaştırıldı.Bulgular: Kız fetuslarda NT değerleri daha yüksekti p= 0.04 . Posterior plasenta grubunda AFP değerleri anlamlı bir şekilde yüksek idi p= 0.04 , ve ilk trimester hCG değerleri posterior plasenta grubunda sınırda anlamlılık gösterdi p = 0.05 .Sonuç: İlk trimester ve ikinci trimester tarama test parametreleri fetal cinsiyet ve plasenta likalizasyonundan etkilenebilir.
