A retrospective comparative study of two definitions of the non‐stress testing employing two and four accelerations associated with fetal movements in 20‐min observation in 304 high risk pregnant women was evaluated. It was shown that four accelerations or more are no more predictive of good outcome than two accelerations during the same period. On the other hand a non‐reactive test is significantly more predictive of poor outcome when two acceleration definition was employed. It was shown in cases with good outcome that the reactivity of the non‐stress test increases with gestational age and that this test is invalid prior to the 33rd week of gestation.
