As such, many patients who have an abnormal second trimester screen opt for less-invasive NIPT over diagnostic testing.ДЄ word about abnormal ultrasound screeningsД¬ounseling patients about abnormal ultrasound findings is more complex than discussing next steps after abnormal screening results. These tests provide the most complete information but do carry a small risk (less than 1 in 300 for amniocentesis)В of pregnancy loss. In the second trimester, you can consider amniocentesis (analyzing the fluid around the baby) or fetal blood sampling. Young women are often surprised to learn that even though their test came back abnormal, the true risk of their baby having Down syndrome is less than 50%.

Enter the condition for which your test came back positive (such as Down syndrome) and the age youвЂ™ll be at delivery. If your pregnancy was considered low risk for Down syndrome but you had an abnormal NIPT, IвЂ™d recommend using this positive predictive value calculatorВ from the National Society of Genetic Counselors to estimate the risk.

However, IвЂ™m seeing more patients select cell free fetal DNA screening to avoid the risks of invasive testing. We usually donвЂ™t recommend having another screening test after you've already had a positive one. In the first trimester, you can consider a diagnostic test such as chorionic villus sampling, which is a biopsy of placental tissue. We do not screen for Down syndrome after the second trimester, but invasive testing can be performed in the third trimester if new ultrasound findings that are worrisome are found later in pregnancy. What options are available for my stage of pregnancy?Д«elow are the diagnostic testing options available during the first and second trimester if screening suggests an increased risk for Down syndrome.

First trimester nuchal translucency screen.

Many patients are choosing to have this test as part of routine prenatal care in the first trimester, even if they are at low risk for Down syndrome.

In July, Olympic gold medal-winning gymnast Shawn Johnson East and her husband, NFL player Andrew East, shared a personal video about their pregnancy вЂ“ and their doctor's concerns that their developing baby might have Down syndrome.ДЄround the eight-minute mark of the video, Shawn and Andrew discuss the moment their doctor discovered two concerning findings at their 20-week ultrasound: the baby's kidneys were dilated (a little more urine visible than normal), and the umbilical cord had just two blood vessels instead of three, which is also called having a single umbilical artery.
