REDWOOD CITY, Calif., Feb. 15, 2013 /PRNewswire/ -- Verinata Health, Inc., a privately-held company dedicated to maternal and fetal health, today presented data demonstrating its approach to detect aneuploidies in maternal blood from multiple gestation pregnancies. (Logo: http://photos.prnewswire.com/prnh/20120425/SF94380LOGO) Contrary to previous study findings by other investigators, this study demonstrated that each fetus in twin pregnancies contributes approximately 50 percent less...

REDWOOD CITY, Calif., Oct. 25, 2012 /PRNewswire/ --Verinata Health, Inc., a privately-held company dedicated to maternal and fetal health, today announced that it has commenced an action against Ariosa Diagnostics, Inc. (Ariosa) and Laboratory Corporation of America Holdings (LabCorp) in federal court in the Northern District of California. The action asserts that Ariosa and LabCorp infringe U. S. Patent No. 8,296,076 (the '076 patent) entitled "Noninvasive Diagnosis of Fetal...

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. Because of the importance of the clinical data, the abstract, entitled Genome Wide Fetal Aneuploidy Detection by Sequencing of Maternal Plasma DNA:...

First-trimester Blood Test Reveals Fetal Gender

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. The researchers discovered that various ratios of two enzymes (DYS14/GAPDH), which can be extracted from a pregnant mother's blood, indicate whether the baby will be a boy or a girl. "Generally, early fetal gender determination has been performed by invasive procedures such as chorionic villus sampling or amniocentesis. However, these...

SAN CARLOS, Calif., Sept. 2, 2011 /PRNewswire/ -- Verinata Health, Inc., a privately-held company dedicated to maternal and fetal health, today announced the issuance of U.S. Patent No. 8,008,018 (the '018 patent) to Stanford University. The '018 patent, entitled "Determination of Fetal Aneuploidies by Massively Parallel DNA Sequencing," covers methods for determining the presence or absence of a fetal aneuploidy, or an abnormal number of fetal chromosomes, by analysis of blood samples from...

(Ivanhoe Newswire) -- 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. Noninvasive prenatal determination of fetal sex could provide an important alternative to invasive cytogenetic determination, which is currently the gold standard for determining sex and single-gene disorders. Amniocentesis has small but...

According to new study published in the American Journal of Obstetrics & Gynecology In 1980 in the United States, approximately 4.5% of all pregnant women were of advanced maternal age. By 2007 that figure had increased to 14%. Women over 35 are at increased risk of giving birth to babies with trisomy 21. In a study published online today in the American Journal of Obstetrics & Gynecology (AJOG), researchers from the Sequenom Center for Molecular Medicine confirmed that DNA sequencing...

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. Down's syndrome, a major developmental disorder also known as trisomy 21, occurs in around one in every 800 live births. Pre-natal diagnosis mainly entails sampling fluid from the amniotic sac enveloping the fetus.  Another technique is called chorionic villus sampling, and it...

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. Now, scientists using powerful genetic techniques are closing in on that goal with tests that require only a blood sample from the pregnant woman. A biotechnology company in San Diego called Sequenom says it will begin selling such a test in June. Another testing technique, developed at Stanford, is...
