A groundbreaking blood test for predicting severe preeclampsia has recently been approved by the FDA, marking a significant advancement in maternal-fetal medicine. Developed by Thermo Fisher Scientific and spearheaded by research at the University of Chicago, this test promises to improve outcomes for pregnant women by enabling earlier and more accurate detection of preeclampsia.

Overview of the New Blood Test

The new blood test targets women between the 23rd and 35th weeks of pregnancy, utilizing biomarkers sFlt1 and PlGF to predict the likelihood of developing severe preeclampsia. These biomarkers provide a more accurate prediction compared to traditional methods, which primarily rely on blood pressure and protein levels in urine.

Research and FDA Approval

The journey to FDA approval involved over a decade of research led by Dr. Sarosh Rana at the University of Chicago, in collaboration with Cedars-Sinai Medical Center. The pivotal study, published in NEJM Evidence, demonstrated the test’s high predictive accuracy and its potential to significantly enhance clinical decision-making in prenatal care​ (University of Chicago News)​​ (MedXpress)​.

Clinical Application and Benefits

This test can be seamlessly integrated into existing clinical workflows, offering several benefits:

Addressing Health Disparities

Preeclampsia disproportionately affects Black women, who face higher rates of complications and mortality. The new blood test offers a promising tool to address these disparities by providing earlier and more accurate diagnoses, thereby improving management and outcomes for high-risk groups​ (MedXpress)​​.

Future Directions and Ongoing Research

Future research aims to further validate the test’s efficacy and explore its broader applications in prenatal care. Studies are ongoing to examine the real-world impact of this biomarker-based approach and to develop therapies based on angiogenic proteins.

These efforts are expected to pave the way for integrating this test into standard prenatal care practices, ultimately enhancing maternal health outcomes.


The approval of this new blood test marks a pivotal moment in the fight against preeclampsia. By enabling early and accurate prediction, it empowers healthcare providers to make informed decisions, potentially saving lives and improving maternal-fetal health. As we look to the future, integrating this test into clinical practice could revolutionize the management of high risk pregnancies.
