Biophysical Profile

If an expecting mother has diabetes, high blood pressure, too much or too little amniotic fluid around the baby, or is past her due date, a biophysical profile or BPP may be recommended. A BPP may also be ordered if the baby does not appear to be growing properly.

A Biophysical Profile is a type of ultrasound done in the third trimester to assess whether the baby is getting enough oxygen in the womb. The BPP assigns a score for these categories: fetal body movements, fetal muscle tone, fetal breathing movements, and amniotic fluid level.

A Biophysical Profile is non-invasive. Before having the test mothers are encouraged to eat because eating seems to cause the baby to move.
