The roll over test is not of value in predicting pregnancy induced hypertension

As a predictor of pregnancy induced hypertension (PIH) the roll over test (ROT) has conflicting predictive values in the literature, possibly as a result of sample size, composition or methodology. In this study the roll over test was performed on 600 African women in their first pregnancy and at 26-32 weeks. The test was positive in 15% of women and had a positive predictive value of only 20%. It is concluded that the roll over test is of no value in the prediction of PIH.
