Gestational hypertension (hypertension only, without proteinuria, normal laboratory testing and absent symptoms)

Estimation of fetal growth and amniotic fluid status at time of diagnosis; if normal, repeat testing only if there is significant change in maternal condition.

NST at time of diagnosis. If nonreactive, perform a biophysical profile BPP; if BPP 8 or NST is reactive, repeat testing only if there is a significant change in maternal condition

Mild preeclampsia (mild hypertension, normal platelet count, liver enzymes and absent maternal symptoms)

Estimation of fetal growth and amniotic fluid status at time of diagnosis; if normal, repeat testing every three weeks

NST and/or BPP at time of diagnosis; if NST is reactive or if BPP 8, repeat weekly. Testing should be repeated immediately if there is an abrupt change in maternal condition.

If estimated fetal weight by ultrasonography is <10th percentile for gestational age or if there is oligohydramnios (amniotic fluid index 5 cm), testing should be performed at least twice weekly
