Preeclampsia is a complex condition of pregnancy involving hypertension and proteinuria usually after 20 weeks gestation. [68] It is associated with poor cytotrophoblastic invasion of the myometrium. Onset of the condition between 20 and 34 weeks gestation, is considered "early". [69]

Preeclampsia superimposed on chronic hypertension occurs when a pregnant woman with chronic hypertension develops signs of pre-eclampsia, typically defined as new onset of proteinuria ≥30 mg/dL (1+ in the dipstick) in at least 2 random urine specimens that were collected ≥4 h apart (but within a 7-day interval) or 0.3 g in a 24-h period.

Poon was the first researcher to have developed an effective first trimester prediction model based on a combination of maternal factors, blood pressure, uterine artery Doppler, serum pregnancy-associated plasma protein-A and placental growth factor for early-onset preeclampsia, achieving a detection rate of 90%, at 5% false-positive rate.
