The research definition of PE is two readings of either of 140/90 at least 6 hours apart plus 300 mg proteinuria in a 24-hour catch. But that will probably be changing as bloodwork definitions become more practical to implement. Clinically, they don't always have time to do a 24-hour catch, especially if you're in labor, so they'll treat preemptively (especially if your liver labs also look bad.)
