Biophysical profile in the treatment of intrauterine growth-restricted fetuses who weigh <1000 g

BPP alone is not a reliable test in the treatment of preterm IUGR fetuses, because of high false-positive and -negative results. The common notion of a good BPP providing reassurance for at least 24 hours is not applicable in severely preterm IUGR fetuses who weigh <1000 g.
