Why that be? People want to know if their children will have a disease People want to know if their children will have a disease Family history of genetic diseases Family history of genetic diseases Maternal age over 35 years old Maternal age over 35 years old Abnormal maternal screening tests, such as AFP Abnormal maternal screening tests, such as AFP Used in the 3 rd trimester to clarify any last minute complications Used in the 3 rd trimester to clarify any last minute complications Application: no diseases and can lead to in vitro fertilization Application: no diseases and can lead to in vitro fertilization

What That Be? 1) women must undress completely, lie down on exam table with hands behind head 2) all the while, blood pressure, breathing, and heart rate are monitored 3) ultrasound will be used to determine: the fetal heartrate, position of the fetus, position of the placenta, the umbilical cord, and pocket of amniotic fluid
