It defines pre-eclampsia as new-onset
hypertension (over 140 mmHg systolic or over
90 mmHg diastolic) after 20 weeks of pregnancy
plus 1 or more new-onset conditions. If a woman
presents with some but not all of these criteria,
they are considered to have suspected pre eclampsia. If they are under 37 weeks of
pregnancy, this would be suspected preterm pre eclampsia.
