Ambulatory blood pressure measurements in mid-pregnancy and development of hypertensive pregnancy disorders

Women can self-measure BP at home. BP readings show diurnal variation. There are significant differences in BP of women who do and do not develop hypertension later in the pregnancy. Use of home BP monitoring over 24 h of the day in mid-pregnancy is unlikely to add to the use of uterine artery Doppler and a one-off BP reading for future development of hypertension in pregnancy.
