It was able to predict the risk of complications in up to 84 per cent of mothers.
The research was carried out at Queen Mary University of London, and funded by the National Institute for Health Research.
Project lead Professor Shakila Thangaratinam, professor in maternal and perinatal health at Queen Mary said: “Women categorised to be low risk could be followed-up in an outpatient setting, with high-and very high-risk women monitored as inpatients with regular intensive monitoring.”
Marcus Green, chief executive of the Action on pre-eclampsia (APEC) charity, which worked with the study team, said: ““This devastating condition frightens patients, comes on quickly, is unpredictable and can kill.
“Knowing when to intervene and when to deliver is crucial and this work is very helpful in identifying the women who really need careful medical attention and to ensure they get the care they need.”
The new research was published in the journal BMC Medicine.
