The researchers observed the accuracy of the test among a group of 625 pregnant women, of which 61 percent had pre-eclampsia, and found that the test was able to accurately detect the condition in 96 percent of women who had a high risk of the condition.
The researchers said that the test can give out an accurate result within 15 minutes.
"Current tests only detect that it's happening, rather than predicting it, and by that time the disease has progressed and likely caused organ damage. The test identifies women at high risk of developing pre-eclampsia, so doctors can better monitor and treat the blood pressure. It also prevents unnecessary hospitalizations of those women who are not likely to develop pre-eclampsia", King's College London's Dr Lucy Chappell said.
