ObGyn Explains: Comprehensive Guide to Prenatal Genetic Testing for Aneuploidy

This pregnancy guide will cover everything you need to know about prenatal genetic screening for aneuploidy. In this Week 9 pregnancy update, we are talking all the options available for prenatal genetic testing--from the first trimester screen, to the quad screen, to cell-free fetal DNA. We also review the diagnostic testing options of chorionic villus sampling and amniocentesis. We cover risks of a genetic abnormality like Down Syndrome, or Trisomy 21, as well as other aneuploidies and microdeletions. We cover what to expect and how to be best prepared to talk with your doctor or midwife about your prenatal care in the first trimester. In this week by week pregnancy guide, we also review baby's development during the 9th week of pregnancy! Looking for more?! Coming in early 2026, we are launching TDB+.
