Clinical inquiries. Do intercontraction intervals predict when a woman at term should seek evaluation of labor

: Intercontraction intervals do not predict when a woman at term should seek evaluation of labor. However, a reduction in the intercontraction interval is associated with active labor. Most primigravidas who have had regular contractions for 2 hours and multigravidas who have had regular contractions for 1 hour have not transitioned into the active phase of labor.
