Perinatologists at the Maternal Fetal Center at Children's Hospital Central California became the first in the region to offer a new blood test for expectant moms. Given at 10 to 20 weeks’ gestation, the cell-free fetal DNA test identifies the chromosomal abnormalities known as trisomy 21 (Down syndrome), trisomy 18 (Edward syndrome) and trisomy 13 (Pateau syndrome).
“The cell-free fetal DNA test can be given earlier in the pregnancy and with a much lower risk than amniocentesis,” said Dr. Armando Fuentes, medical director, perinatology, Children’s Hospital. “It’s a noninvasive test that detects Down syndrome with a 98.9 percent rate of accuracy.”
The Maternal Fetal Center offers the new test to high-risk moms who will be at least 35 years old at the time of delivery, had a prior pregnancy with chromosomal abnormalities or received a positive result on their maternal serum screening test.
