What this trial studies

This observational study aims to validate the MaiRa Preeclampsia Test, a molecular screening tool designed to predict early-onset and late-onset preeclampsia during the first and second trimesters of pregnancy. The study will involve 7,473 pregnant women from 12 tertiary hospitals in Spain, who will provide blood samples at various stages of their pregnancy. The test's diagnostic accuracy will be evaluated by comparing results against obstetric outcomes, with a focus on improving early detection and intervention strategies for preeclampsia.

Who should consider this trial

Good fit: Ideal candidates for this study are pregnant women aged 18 and older with single gestation pregnancies who can provide a blood sample between 9 and 14 weeks of gestation.

Not a fit: Patients with active neoplasms, a history of organ or bone marrow transplantation, or severe uncontrolled infections may not benefit from this study.

Why it matters

Potential benefit: If successful, this test could significantly enhance early detection of preeclampsia, leading to timely interventions that improve maternal and fetal outcomes.

How similar studies have performed: Previous studies, such as the PREMOM study, have shown promise in using cell-free RNA analysis for early prediction of preeclampsia, indicating potential success for this approach.
