Fetal Testing and Genetic Screening

Early and regular visits to your obstetrician are critically important during your pregnancy. The care you receive throughout your pregnancy is vital to your health and the health of your unborn baby. The ob-gyn doctors and staff at Northside/Northpoint OB-GYN of Atlanta and Alpharetta, GA make you and your unborn baby our number-one priority. We want to guide you through the most beautiful time of your life to that special day when your baby is born.

Our fetal testing includes:

  • OB ultrasound services

  • Early OB ultrasound

  • Nuchal translucency

  • 18- to 20-week OB ultrasound for fetal assessment

  • Biophysical profile for testing of fetal well-being (fetal movements, breathing, tone and fluid levels)

  • NST: Non-stress test traces the fetal heart rate, confirming the fetal health

  • 3D ultrasound

Optional Genetic screening

Please be aware that our office cannot pre certify OPTIONAL testing

Screening is offered to all patients for carrier testing for genetic diseases including:

Inheritest – Integrated Genetics Carrier Screening – a blood test for 12+ conditions that can be passed from parent to child even if neither parent has the clinical disease or any symptoms. Insurance coverage and preauthorization are addressed by the laboratory directly 844-799-3243

MaterniT21 – Integrated Genetics Noninvasive Prenatal Testing (NIPT) – a blood test that detects fragments of fetal DNA in maternal blood to screen for Trisomy 21 (Down syndrome), Trisomy 18, Trisomy 13, and disorders of the X and Y chromosomes. This test is highly sensitive and can be done as early as 9 weeks of pregnancy. Insurance coverage and preauthorization are addressed by the laboratory directly 844-799-3243. The maximum out of pocket will be $299.00.

NTD Lab First Screen – a blood test that is performed by NTD labs in conjunction with an ultrasound of the nuchal fold between 12 and 14 weeks or pregnancy.  This test screens for Trisomy 21 (Down Syndrome), Trisomy 18, and Trisomy 13.  The ultrasound also offers an early anatomical assessment of the baby and can detect some additional abnormalities.  Benefits for the ultrasound can be checked by calling your insurance company (CPT 76813).  Benefits for the blood test component can be checked by calling your insurance company (CPT 84163, 84704) and/or NTD laboratory directly 888-683-5227

If a woman will be 35 years of age at the time of delivery, she can elect to have invasive genetic testing for Down syndrome with either chorionic villus sampling (CVS) or amniocentesis.

Amniocentesis is performed at approximately 16 weeks. Using ultrasound guidance, a thin needle is used to withdraw fluid from around the baby.

CVS is performed at approximately 10 to 12 weeks and involves sampling tissue from the placenta under ultrasound guidance. The accuracy of these tests is 100%; however, there is a small risk of miscarriage. Amniocentesis has a lower pregnancy loss risk but the test is performed later in pregnancy. Any patient can consider these invasive tests but the benefits probably do not outweigh the risks unless the mother is age 35 or older, there is a personal or family history of genetic disease, or any previous genetic testing resulted in abnormal findings.
