Nonstress test

Reactive Nonreactive

Fetal tone One or more extensions of arm/leg; closing of hand

Fetal breathing movements

One or more lasting at least 30 seconds within a 30-minute interval

No FBM in 30 minutes

The biophysical profile (BPP) combines a nonstress test (NST), with an ultrasound examination checking for four different parameters. Each of the 4 ultrasound parameters plus the non-stress test get a score between 0 and 2 and are added up for a total maximum score of 10.

The ultrasound part of the biophysical profile exam checks four different indicators:

Fetal tone Fetal breathing

Fetal movements

Amniotic fluid volume
