Is the supine pressor test an adequate means of predicting acute hypertension in pregnancy?

Abstract

The supine pressor test was performed on 207 nulliparous young women between the twenty-eighth and thirty-second weeks of gestation. The supine pressor test predicted pregnancy-induced hypertension in 78 per cent of those women who subsequently developed the condition. Ninety-six per cent of the women who failed to demonstrate a rise in diastolic pressure on position change remained normotensive throughout the remainder of the pregnancy.
