OB | Diagnostic Testing & Screenings

About this episode

This episode discusses various diagnostic tests and screenings used in obstetrics, focusing on ultrasounds and their applications.

Abdominal ultrasounds are more useful after the first trimester when the uterus is larger. What they screen for: Ultrasounds confirm pregnancy, determine gestational age, identify multifetal pregnancies, evaluate fetal growth and position, and check for fetal viability or abnormalities. They also assess maternal structures and amniotic fluid volume. A Doppler ultrasound specifically measures maternal-fetal blood flow . Additionally, an ultrasound assessing nuchal translucency between 11 and 13 weeks of gestation can suggest the presence of Down syndrome (trisomy 21) if increased thickness is found. Biophysical Profile (BPP) When it is performed: Typically used when a nonstress test is nonreactive or if hypoxia is suspected. What it screens for: It assesses overall fetal well-being and the risk of chronic fetal asphyxia by combining a nonstress test with an ultrasound to score five variables: fetal heart rate (FHR)…
