What is the maximum score possible on a biophysical profile when a NST is included?

In a biophysical profile (BPP) that includes a non-stress test (NST), the maximum possible score is 10. The BPP assesses five parameters of fetal well-being: fetal heart rate, fetal breathing movements, fetal movement, fetal tone, and amniotic fluid volume. Each of these four ultrasound parameters is given a score of 2 (2 points for normal findings and 0 for abnormal findings), which totals 8 points.

Additionally, the non-stress test contributes 2 more points based on fetal heart rate patterns, specifically looking for reactivity. Therefore, when the non-stress test is included, the total maximum score achievable in a BPP is 10 points. This scoring system effectively evaluates both the fetal environment via ultrasound and fetal cardiac activity via the NST, providing a comprehensive assessment of fetal health.
