Biophysical Profile (BPP)

A biophysical profile (BPP) test is done to:

• Learn about and keep track of your baby's health. Special ultrasound methods are used to keep track of movement, increases in heart rate with movement (nonstress test), muscle tone, breathing rate, and the amount of amniotic fluid (Reference amniotic fluid index Opens New Window) surrounding your baby. If these five areas are within a normal range, your baby is considered to be in good health.
