Q: All of the following is diagnostic of Preeclampsia with systolic blood pressure of more than or equal to 140 mmHg or diastolic blood pressure more than or equal to 90 mmHg except

A) Proteinuria more than or equal to 0.3 grams in a 24-hour urine specimen
B) Protein:creatinine ratio more than or equal to 0.3
C) Platelet count less than 100,000/microliter, 
D) Serum creatinine more than 1.1 mg/dL or doubling of the serum creatinine, 
E) Elevated serum Bilirubin to twice normal concentration


Answer: E

Diagnosis of preeclampsia is certain when a woman with normal blood pressure pre pregnancy develops hypertension and either proteinuria or end-organ dysfunction after 20 weeks of gestation. Criteria for diagnosis includes all of the above except bilirubin level. Instead it requires elevated serum transaminases to twice normal concentration.
