Women May Soon Be Able to Determine Their Risk for Miscarriage Through This Special Blood Test

 blood tests may predict miscarriage

Since there are multiple factors that could eventually lead to a pregnant woman having a miscarriage, many agree that doing things to aid in prevention is every mother's best bet. Most women who smoke during pregnancy, are under extreme stress, or are dealing with health problems often understand early on that the possibilities of their unborn babies not making it to term are higher. But others are left wondering and worrying about how high their risk actually is. Instead of spending your entire pregnancy in fear, researchers are now claiming that all women will soon be able to know if they have a high miscarriage risk with a simple blood test.  


Scientists at the Laboratory of Premature Medicine and Immunology in San Francisco, California, recently claimed to have developed a blood-work technique that allows medical professionals to detect possible complications early on during a woman's pregnancy.

According to their finding, researchers discovered that molecules on the membrane that lines the uterus (placenta bed) have the ability to predict preeclampsia -- a usually mild condition that can lead to high blood pressure and swollen hands or feet in pregnant women -- and miscarriages in women with 90 percent accuracy. Expectant moms can get these results all before the women have even exhibited any troubling symptoms. 

The blood tests are meant to target molecules called "microRNA," which are thought to be indicators of blood supply issues that often lead to pregnancy complications. "Our combined analysis supports the idea that the Great Obstetrical Syndromes [miscarriage, preterm labor] have a common biological origin early in the first trimester that can be detected throughout the first trimester using peripheral blood cell microRNA," the researchers wrote. 

To come to this conclusion, they conducted four different studies, overall examining 160 different births. With their research, scientists were able to successfully predict miscarriage and preeclampsia in pregnancies with 90 percent accuracy as well as premature births before 34 weeks with 89 percent accuracy. Premature births between 34 and 38 weeks were predicted with 92 percent accuracy. 

Researchers are now arguing that these findings will go on to allow expectant moms to determine their pregnancy risks with regular blood tests in conjunction with other common pregnancy screenings.

Of course, as scientists do not yet have a known way of preventing miscarriages, these tests would only help give women a clearer understanding of what they may need to prepare for. For premature births, researchers argue that doctors who are aware that their patients may be dealing with high-risk pregnancies may be able to monitor them more closely and take preventative measures to help delay the birth date.

The researchers did not specify how long it would be before patients and physicians actually begin utilizing these tests in facilities. 

Barbara Hepworth-Jones, vice chair of the Miscarriage Association, told the Telegraph, "This is very welcome news. Much research is still needed before we fully understand the causes of pregnancy complications including miscarriage, and can then look for treatments, but this holds real hope for the future."
