[Significance of mean arterial blood pressure in the 2d trimester and the roll-over test for gestosis screening in normal, overweight and underweight primigravid patients].

Possibility of early diagnosis of pregnancy-induced hypertension via mean arterial pressure (MAP-2) and roll-overtest (ROT) was investigated in 80 normal, overweight or underweight primigravidae. The positive and negative predictability, the sensitivity, specificity and effectivity did not correspond to the efficiency of a good screening method. Obese primigravidae have more positive tests than normal. In the MAP-2 this was due to methodical errors, whereas in the ROT hydrostatic mechanisms interferet according to the overweight of the tested person. With these two screening tests, very early PIH diagnosis is generally not possible.
