A new study revealed a blood test conducted in the first three months of pregnancy that can accurately determine women at the risk of developing pregnancy 5 months before the diagnosis, and this disclosure is a major achievement in prenatal care for a common and dangerous condition that occurs during pregnancy.
PRECLAMPSIA is a condition that affects some pregnant women, and is usually during the first half of pregnancy and includes high blood pressure and the appearance of protein in the urine (Proteinuria).
The study was conducted by researchers from the Carlos Simon Foundation in Spain, and the results of the study were presented at the forty -first annual meeting of the European Association for Human Representation and Furnis held in the French capital, Paris, between June 29 and July 2, and wrote the Yorik Alert website.
Pregnancy poisoning is a major reason for mother and child diseases all over the world, and the current examination methods in the first three months of pregnancy depend on risk factors related to the mother or chickenpox indicators, but they fail to detect more than half of the cases, and the risk is often discovered only after this condition begins to develop already.
The researchers recorded nearly 10,000 pregnant women from 14 hospitals across Spain between September 2021 and June 2024.
The researchers succeeded in predicting both early and late poisoning before the symptoms appeared using a sample of the mother’s blood plasma using free RNA in the blood circulation (Circulating Cell-Free RNA).
Routine blood sample
The free cellular DNA is located in biological fluids independently of the cells, and is called from the various tissues of the body to blood circulation.
The free RNA in the blood circulation can capture precise molecular signals of the multiple mother’s tissues, including the uterus and the placenta, months before the symptoms appear.
Blood samples were collected at multiple time points during pregnancy: 9-14 weeks, 18-28 weeks, and more than 28 weeks or upon diagnosis, and free RNA in blood circulation was extracted from 548 plasma samples from 216 selected posts.
“For the first time, we have shown that a routine blood sample in the first trimester of pregnancy can give an early warning for high accuracy of pregnancy, long before the symptoms appear.”.
She added, “Determining high -risk pregnancies at this early stage opens an important window for preventive therapy and accurate monitoring to protect mothers and children.”
