Roll over test.

Eighty-eight primigravidas underwent a roll over test performed according to the method suggested by Gant. A single individual performed the tests, and the results were withheld from the physician taking care of the patient. After delivery, 14 cases were excluded for various reasons, and, of the remaining 74 patients, 27 had negative results. Of these, 19 (70.4%) results were true negative and 8 (29.6%) were false negative. Forty-seven patients had a positive roll over test, of whom 35 (74.5%) did not develop hypertension in pregnancy and 12 (25.5%) did. The authors' results did not confirm the reliable predictive ability of the roll over test as reported by Gant and other investigators.
