What does a reactive non-stress test indicate?

A reactive non-stress test (NST) is a sign of good fetal health and indicates favorable conditions for fetal well-being. During the NST, the fetal heart rate is monitored for accelerations in response to fetal movements. When the test is reactive, it means that the fetus has a healthy heart rate pattern, reflecting adequate oxygenation and neural development.

This positive outcome suggests that the fetus is likely to be well-oxygenated and not under stress, which is essential for both fetal and maternal peace of mind during pregnancy. It can be seen as an indication that the fetus can adequately respond to stimuli, which is an important sign of overall health.

In contrast, the other options represent conditions that are either neutral or unfavorable. For instance, a non-reactive NST could suggest fetal distress or the need for further testing, while unfavorable conditions for fetal well-being would indicate a potential risk to the fetus's health.
