About Our Center

The Inova Loudoun Hospital Antenatal Testing Center (ATC) provides specialized care and comprehensive diagnostic testing for women throughout their pregnancy. We've cared for thousands of expectant mothers and regularly work with women whose pregnancies are considered high-risk.

Our center is staffed with maternal/fetal medicine specialists (perinatologists), perinatal sonographers, and nurses whom work hand-in-hand with obstetricians and midwives. We use state-of-the-art technology–including the VE Volusion® E10, a high-resolution 4D ultrasound–to help our team view and detect fetal abnormalities earlier than ever. Our antenatal testing center features all-private patient rooms equipped with 40-inch high-definition televisions for viewing.

Specialized Tests

Nuchal Translucency Screening

The Nuchal Translucency Screening test can determine your baby's risk of having major congenital heart problems, Down syndrome or other chromosomal abnormalities. Our testing center was the first in Northern Virginia to perform the screening and our physicians and sonographers are Nuchal Translucency credentialed. Our physicians and sonographers are Nuchal Translucency credentialed by the Maternal-Fetal Medicine Foundation.

We provide same-day results with your ultrasound, provided that you have your blood drawn a week in advance. For your convenience, patients between their 10th and 11th week of pregnancy can have their blood drawn at our center.

Cell-Free DNA Screening

The Cell-Free Fetal DNA Screening tests the baby’s DNA that is in your blood. It checks for certain abnormal chromosomes. It can also check for defects in the fetal sex chromosomes (X and Y). Cell-free fetal DNA screening does not find structural birth defects, such as spina bifida or defects in the abdominal wall. This test can be completed between 10–35 weeks gestation and is able to identify your baby’s gender.

If first trimester screening is abnormal, you may need more testing for diagnosis. This may include chorionic villus sampling, amniocentesis, or another ultrasound.

What Makes a Pregnancy High-Risk?

Factors which may cause a woman’s pregnancy to be considered high risk include:

  • Pre-existing conditions such as diabetes or hypertension
  • Older mothers (over the age of 35)
  • Women with multiple pregnancies
  • Those women who experience unexpected complications caused by pregnancy
  • Parents who pass on a genetic disorder and develop a baby with an inherited growth abnormality
