Labcorp has unveiled a groundbreaking FDA-cleared blood test designed for assessing and managing severe preeclampsia, a potentially life-threatening blood pressure disorder occurring during pregnancy and the postpartum period. Affecting 2-5% of pregnancies, preeclampsia poses significant risks to both maternal and neonatal health, and conventional diagnostic methods like blood pressure and proteinuria assessments often fall short in predicting severe outcomes.
Developed by Thermo Fisher Scientific and recognized as one of TIME Magazine’s Best Inventions of 2023, the new test measures two angiogenic biomarkers linked to preeclampsia: serum soluble fms-like tyrosine kinase 1 (sFlt-1) and placental growth factor (PlGF). By analyzing the ratio of these biomarkers, along with other clinical assessments, the test aids clinicians in identifying pregnant patients at risk of progressing to severe preeclampsia within two weeks of testing.
Validated by the PRAECIS study involving over 1,000 pregnant women across 18 U.S. hospitals, the blood-based test is intended for singleton pregnancies between 23+0 and 34+6/7 weeks gestation. Positive results, indicated by an sFlt-1/PlGF ratio ≥ 40, prompt enhanced surveillance and accelerated care, allowing for proactive management before severe features manifest.
Labcorp’s collaboration with Thermo Fisher aligns with their commitment to advancing diagnostic capabilities, supporting healthcare providers with early and objective information for improved preeclampsia management. The test aims to contribute to better outcomes for both parents and newborns by offering comprehensive and advanced diagnostic solutions in line with Labcorp’s mission to enhance health and lives.
