Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are pregnant women in their first trimester who are carrying a single live fetus and have a hemoglobin level of 11 g/dL or higher.

Probably not a fit

Patients with a history of certain medical conditions such as diabetes, hypertension, or gastrointestinal diseases, as well as those on specific medications, may not benefit from this study.

What this trial studies

This observational study aims to establish reference intervals for iron biomarkers such as serum iron, ferritin, total iron-binding capacity (TIBC), and transferrin saturation (TSAT) in healthy pregnant women during their first trimester. It will also investigate the prevalence of non-anemic iron deficiency (NAID) in this population. By applying strict inclusion and exclusion criteria, the study seeks to provide a reliable baseline for evaluating iron status and early detection of iron deficiency without anemia among pregnant women. The study will take place at antenatal care clinics at Hung Vuong Hospital in Ho Chi Minh City, Vietnam, from March to June 2025.

Why it matters

Potential benefit: If successful, this study could lead to improved early detection and management of iron deficiency in pregnant women, potentially enhancing maternal and fetal health outcomes.

How similar studies have gone: While there is limited data on the prevalence of non-anemic iron deficiency in early pregnancy, similar studies have successfully established reference intervals for iron biomarkers in other populations.
