What is a biophysical profile?
This is an ultrasound assessment of fetal well being. It is based on a scoring system where several components are observed over a 30 minute period. The components are: amniotic fluid volume, non-stress test, fetal breathing movements, gross body movements, fetal tone (limb or trunk extension with return to flexion). These responses are observed and if present a score of 2 is given, if absent a score of 0 is given with 10 possible points.
