Determining whether elevated blood pressure identified during pregnancy is due to chronic hypertension or to preeclampsia is sometimes a challenge, especially if no recorded blood pressures from the first half of the gestation are available. Clinical characteristics obtained via history, physical examination, and certain laboratory investigations may be used to help clarify the diagnosis. See Introduction for important maternal and fetal risk factors for preeclampsia that are essential to the history.
