In the new classification, proteinuria is not the main indicator for diagnosis of preeclampsia.The percentage of false-negative proteinuria, especially on the dipstick, is high. Preeclampsia may be classified according to the time of event into two groups: Early (preeclampsia before 34 weeks of gestation) and Late (preeclampsia after delivery). Preeclampsia with severe feature includes the following characteristics: systolic blood pressure ≥ 160 mmHg, diastolic blood pressure ≥ 110 mmHg, in two occasions apart 4 hours, thrombocytopnea (platelet count <100,000/dl), pulmonary edema, new-onset headache unresponsive to medications, visual disturbances, liver enzyme level > 2 times upper limit normal concentrations or persistent epigastric or right upper quadrant pain, and serum creatinine >1.1 mg/dl or doubling serum creatinine level in the absent of other causes of renal insufficiency.
