  • Patent number: 11965893
    Abstract: This invention relates to the use of biomarker LRG1 as a biomarker for preeclampsia for use from the first trimester. Elevated levels of leucine-rich alpha 2 glycoprotein 1 (LRG1) can predict risk for the future development of preeclampsia or other hypertensive disorders of pregnancy. The predictive test will comprise the measurement of LRG1 protein, peptide fragment, DNA or RNA, from either blood, plasma, serum, urine, saliva or amniotic fluid. The invention provides a method and a test kit to assess the risk of pre-eclampsia in pregnant woman. The method or test can utilise antibodies to measure levels of LGR1 in a sample.
