Monitoring miscarriage through a blood test

Official title: Non-invasive Monitoring of Miscarriage

Run by Chinese University of Hong Kong · NCT06581692 · Data updated 2026-11-12

This study is testing a blood test that looks at DNA to see if it can help understand the genetic reasons behind miscarriages in women who have had early pregnancy loss, especially those who used fertility treatments.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are women aged 18-45 who attend an early pregnancy loss clinic or have received ART.

Probably not a fit

Patients with a history of psychological or psychiatric problems or those who refuse participation may not benefit from this study.

What this trial studies

This observational study focuses on the use of cell-free DNA (cfDNA) to identify chromosomal causes of miscarriages during early pregnancy. It compares cfDNA levels obtained from a simple blood test with results from product of conception (POC) testing and standard karyotyping. The study specifically targets women who have experienced early pregnancy loss, particularly those who have undergone assisted reproductive technologies (ART). By analyzing cfDNA, the study aims to provide insights into the genetic factors contributing to miscarriages.

Why it matters

Potential benefit: If successful, this approach could lead to a non-invasive method for diagnosing chromosomal abnormalities in miscarriages, improving patient care and understanding.

How similar studies have gone: Other studies have shown promise in using cfDNA for genetic analysis, suggesting potential success for this approach.
