Sequential evaluation of the supine hypertension or 'roll-over' test in a high risk population
The supine hypertensive or 'roll-over' test (ROT) was performed serially in 24 primigravid patients between 27 and 35 weeks of gestational age. Pregnancy-induced hypertension (PIH) developed in 3 women (12.5%). Test producibility one week to the next in the same patient was poor. A false-positive ROT was noted for 83% of our patients a false-negative test for 12.5%. We conclude that serial testing reveals marked variations in response that reflect inherent biologic fluctuations that limit the predictive value of the ROT for screening outpatients.
