Biophysical Profile

A biophysical profile (BPP) is a test that combines a non-stress test with ultrasound. A non-stress test (NST) measures the fetal heart rate in response to the movements of the fetus. An ultrasound is a diagnostic technique that uses high-frequency sound waves to create an image of the internal organs. Biophysical profile testing is usually performed in the last trimester of pregnancy.

There are five parts to a biophysical profile:

  • the non-stress test
  • plus four areas assessed by ultrasound:
    • fetal breathing movements
    • fetal movements
    • fetal tone
    • amniotic fluid volume

Biophysical Profile Scoring

Each of the five areas of the biophysical profile has a possible total score of two points, for a total of 10 points.

If the score is questionable or abnormal, or if the amniotic fluid volume is too low, additional testing may be needed.
