About this trial
This cross-sectional study aims to establish reference intervals for iron biomarkers-including serum iron, ferritin, total iron-binding capacity (TIBC), and transferrin saturation (TSAT)-in healthy pregnant women during the first trimester. Additionally, the study will investigate the current prevalence of non-anemic iron deficiency (NAID) in this population. By applying strict inclusion and exclusion criteria to eliminate potential confounding factors, the study seeks to provide a reliable baseline for evaluating iron status and early detection of iron deficiency without anemia among pregnant women.

Trial outcomes
Primary outcomes
Prevalence of iron supplement using women that has non-anemic iron deficiency in the first trimester
Non-anemic iron deficiency is defined as hemoglobin ≥ 11 g/dL and transferrin saturation (TSAT) \< 20%. The prevalence will be calculated as the proportion of enrolled pregnant women meeting these criteria
Prevalence of non iron supplement using women that has non-anemic iron deficiency in the first trimester
Non-anemic iron deficiency is defined as hemoglobin ≥ 11 g/dL and transferrin saturation (TSAT) \< 20%. The prevalence will be calculated as the proportion of enrolled pregnant women meeting these criteria
Reference Intervals for Iron Biomarkers in the First Trimester
Establish reference intervals (2.5th-97.5th percentile) for serum iron, ferritin, TIBC, and TSAT in healthy first-trimester pregnant women meeting inclusion criteria
