Latest Diagnosis of fetal aneuploidy Stories
In a study to be presented today at the Society for Maternal-Fetal Medicine's annual meeting, The Pregnancy Meeting ™, in Dallas, Texas, researchers will report findings that indicate that massively parallel sequencing can be used to diagnose fetal aneuploidies, including Down syndrome, Edwards syndrome, Patau syndrome and Turner syndrome.
A new South Korean study could pave the way for a simple, non-invasive test that predicts fetal gender as early as the first trimester of pregnancy.
As a noninvasive method of determining the sex of a fetus, tests using cell-free fetal DNA obtained from the mother's blood after 7 weeks gestation performed well, while urine-based tests appear to be unreliable, according to this study.
In 1980 in the United States, approximately 4.5% of all pregnant women were of advanced maternal age.
Research published on Tuesday states that DNA in a pregnant woman's blood can reliably show whether her fetus has Down's syndrome, which can reduce the need for invasive testing procedures like amniocentesis.
By Andrew Pollack For three decades, scientists have been trying to develop a noninvasive prenatal test for Down syndrome that would replace amniocentesis, which can cause miscarriages.
