摘要：In our study it was aimed to research the relations between pregnancy complications and frequencies of maternal and fetal complications which can be observed after the further follow-ups with biochemical indicators in gravid individuals whom found to be risky in quad test.120 patients who applied and had their labors conducted in İstanbul Training and Research Hospital and took quad test AFP (alpha fetoprotein), HCG (human chorionic gonadotropin), uE3 (unconjugated estriol), inhibin-A are included in our study. Conclusions planned to be obtained in this study are, IUGR (intrauterine growth deficiency), macrosomia, gestational diabetes, preeclampsia and preterm birth. 64 (% 53, 4) out of 120 patients participated in the study had normal labors while 56 (F, 6) of the patients had labors with caesarean birth. On 70 (X.3) patients whom did not develop obstetric complications, AFP value calculated as average as 1.00±0.74 MoM, uE3 value calculated as 0.89±0.4 MoM, hCg value calculated as 0.97±0.5 MoM and inhibin A value calculated as an average of 0.95±0.5 MoM. On 50 (A.6) patients whom developed obstetric complications, AFP value found as average of 1,06±0,74, uE3 value found as 0.96±0.39 MoM, hCG value found as 0.99±0.77 MoM and Inhibin A value found as 1.023±0.62 MoM. There were no significant deviation between the cases with obstetric complications and cases without obstetric complications in terms of AFP, uE3, HCG and Inhibin A values. There were no significant relation between threshold values of AFP, HCG, uE3 and inhibin A which are used in quad test as secondary trimester serum indicators in low risk populations and pregnancy complications.
