This finding can guide clinicans for early diagnosis and management of such outcomes. However, previous finding are conflicting in this regard. Therefore, this study evaluated the detection of adverse pregnancy outcomes by first- and second-trimester serum screening analytes.Methods & Materials: We prospectively recruited 972 females who underwent first and second-trimester aneuploidy screening. We gathered information on maternal demographic characteristics and serum biomarkers (free B-hCG and PAPP-A for the first-trimester; AFP, Β-hCG, Inhibin-A, and unconjugated estradiol for second-trimester). At the end of the study, adverse pregnancy outcome was recorded.Results: Abnormal screening results were reported in 34 (3.5%) patients. Two groups were significantly different in maternal age, BMI, and gestational period (P < /em>=0.017, 0.003 and 0.021, respectively). Among the measured adverse outcomes, preeclampsia was significantly more prevalent in the case group (P < /em><0.0001). Abnormal levels of Inhibin-A is associated with the incidence of preeclampsia (RR: 29.87, CI: 13.22-67.49, P < /em><0.0001). Additionally, patients with an abnormal level of Inhibin-A had a shorter gestational period (255.5 ± 24.53 vs. 264.79 ± 8.99, P < /em>=0.006). Likewise, patients with an abnormal level of maternal serum alpha-fetoprotein (MSAFP) had a shorter gestational period (252.0 ± 29.3 vs. 264.8 ± 8.93, P < /em>=0.001).Conclusion: First- and second-trimester maternal serum biomarkers could provide a possible screening tool for early detection of preeclampsia.}, keywords = {Pregnancy Complications,Maternal serum markers,Pregnancy}, url = {https://www.jogcr.com/article_697229.html}, eprint = {https://www.jogcr.com/article_697229_9f5e8bc5b9446c829bab599086de6fea.pdf} }
