The utility of the roll‐over test (ROT) as a prognostic tool for predicting pregnancy‐induced hypertension (PIH) was examined in primiparas in Quito, Ecuador. In Study I, 14 of 16 subjects with a + ROT developed PIH (positive predictive value (PPV) = 88%); only 2 of 27 subjects with a ‐ ROT developed PIH (negative predictive value (NPV) = 92.5%). In Study II ( n = 66), the PPV and NPV were 71.4% and 78.6%, respectively. Data from these and previous studies indicate that although the ROT is not a perfect predictor, its advantages recommend usage in populations with high PIH‐associated maternal and perinatal mortality.
