The diagnosis of preeclampsia is based on findings of raised blood pressure (over 140/90mmHg) and the presence of proteinuria. The accepted means of measuring proteinuria is by 24-hour urine collection, with a pathological value defined as 300mg or greater in the 24 hour period. When the proteinuria is greater than 5000mg in 24 hours, the pr-eclampsia is classified as severe and is further endangers the lives of the expectant mother and fetus and often results in early delivery.
