A novel field suggests that asimple blood testtaken by mothers during early pregnancy could indicate their risk of miscarriage . If picture to be true , this would be a major whole tone in identifying women who may be in danger of both miscarriages and previous birthing before symptoms ever show . But many expert are stressing caution about the effect , as the written report was small and holds “ a in high spirits risk of them being improper . ”
The late inquiry follow from a squad working at the Laboratory for Reproductive Medicine and Immunology in San Francisco . The researchers see that a certain molecule in the blood may give away which women have a high luck of go on to have a miscarriage , which in twist could assist doctor instal new ways to prevent it from pass off in the first seat .
The results were present at theAmerican Society for Reproductive Medicinemeeting , but other experts have been nimble to posit their question about the study . While the results are interesting and warrant further research , they caution that the sketch was small and only at a preliminary stage .
The team studied 160 births in amount , with the research worker look at the line of significant mothers for a molecule sleep with as microRNA . The Dr. consider that these molecules show signs that big mothers are more potential to recrudesce complications . They say that their analysis of the microRNA allowed them to auspicate with 90 percent truth which women would have a abortion and pre - eclampsia . They also were able to determine with 89 percent accuracy who would have a premature birth before 34 weeks .
Miscarriage , particularly if it is a woman ’s first pregnancy , is not an rare natural event . In fact , it is thought that between 15 and 20 percent of all pregnancies in the US will terminate up in the loss of the fetus before the twentieth hebdomad . On the other hand , pre - eclampsiais more likely to pretend women in the second half of their gestation , in which gamey profligate pressure and vision problem can rise .
Others , however , are not as convert by the results . While they say the results are intriguing , they also stress that far more enquiry needs to be done to full investigate the extent of these claims .
“ Although the results might seem exciting and swerve edge , there is alas a high risk of them being wrong , ” prof of clinical embryology at the University of Manchester , Daniel Brison , toldBBC News . “ We ’d need bigger follow - up studies to be certain whether these results are valid . ”
