Advantages and limitations of NST

  1. Some advantages of NST are that it is safe, simple, noninvasive, inexpensive, widely available, and well-tolerated by mothers and fetuses. It has a high negative predictive value, meaning that a reactive result reliably excludes fetal hypoxia or acidosis. It can also be repeated as often as needed without adverse effects.

  2. Some limitations of NST are that it has a low positive predictive value, meaning that a nonreactive result does not necessarily indicate fetal compromise. It may also have false-positive or false-negative results due to factors such as maternal medications, fetal sleep cycle, maternal obesity, or technical errors. It also does not provide information about other aspects of fetal well-being such as amniotic fluid volume or fetal breathing movements.

Technical errors, such as poor transducer placement or loose belts, can also interfere with the accuracy of the NST.

A biophysical profile (BPP) is a prenatal test that evaluates the well-being of the fetus by combining an ultrasound examination with a nonstress test. The test assesses five components: fetal heart rate, breathing, movement, tone, and amniotic fluid volume. Each component is scored as 2 (normal)
