 Preeclampsia: Judging Severity^a

	Less Severe	More Severe
Presentation	≥Gestational week 34	≥Gestational week 35
Diastolic BP	<100 mm Hg	>110 mm Hg
Headache	Absent	Present
Visual disturbances	Absent	Present
Abdominal pain	Absent	Present
Oliguria	Absent	Present
Creatinine (GFR)	Normal	Elevated (decreasing)
LDH and AST proteinuria	Normal mild to moderate	Elevated nephrotic range (>3 g/24 h)b
Nonreassuring fetal testingc	Absent	Present

The American College of Obstetrics and Gynecology bulletins utilize the terms mild and severe for our preferred less and more severe, so as to underscore diligence for any form of preeclampsia. Abbreviations: AST, aspartate aminotransferase; BP, blood pressure; GFR, glomerular filtration rate; LDH, lactic acid dehydrogenase. ^aPresence of convulsions (eclampsia), congestive heart failure, or pulmonary edema are always very ominous signs. ^bDegree of proteinuria alone may not indicate seriousness unless accompanied by other ominous sign or symptom. ^cGrowth restriction and adverse signs during periodic fetal testing including electronic monitoring and Doppler ultrasound.
