Check Out This Study: Blood Test Could Predict Preeclampsia Months Before Symptoms Start
The study was published in January 2022 in the journaland conducted by researchers from King’s College London, Guy’s and St Thomas’ NHS Foundation Trust, and Mirvie. It looked at over 1,840 pregnancies occurring in North America, Europe and Africa. The researchers looked at RNA molecules—this is similar to DNA in that it helps with gene expression—in blood samples. The researchers then created a timeline for a normal pregnancy and looked at different gene activation patterns week over week.
“I think the real impact of this technology we’re looking at is a little bit bigger than just preeclampsia,” Thomas McElrath, study co-author and OB-GYN at Brigham and Women’s Hospital in Boston,. “We hope to look at other clinically meaningful deviations, such as, potentially, gestational diabetes or growth restriction or other areas. Once we basically have a road map of normal cases, where there’s a deviation off of that map then becomes much easier to discern.
In the study, a third of the patients predicted to develop preeclampsia did wind up getting diagnosed with the condition. Plus, researchers were able to correctly identify 75 percent of the cases that later were diagnosed as preeclampsia. They believe their test may be able to help predict preeclampsia a few months before any symptoms show up. While more work is needed, researchers are hopeful they’re on the right track to catching preeclampsia and other pregnancy complications early.
