What this trial studies

This study evaluates the risk factors associated with spontaneous abortion by analyzing serum biomarkers, immunologic factors, and ultrasound parameters. It aims to determine the added value of these combined assessments in predicting miscarriage risk. Participants will undergo evaluations to visualize fetal structures and heart pulsations, alongside testing for specific serum and immunologic markers. The study is observational and does not involve any experimental treatments.

Who should consider this trial

Good fit: Ideal candidates are pregnant individuals who can visualize fetal structures and heart pulsations by the 8th week of gestation and meet specific health criteria.

Not a fit: Patients who do not have visualized fetal structures or heart pulsations by the 8th week, or who have elevated thyroid hormone levels or uterine malformations, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved risk assessment for miscarriage, allowing for better management and support for expectant mothers.

How similar studies have performed: While the approach of using biomarkers and ultrasound for miscarriage risk assessment is not widely established, similar studies have shown promise in identifying risk factors for pregnancy complications.
