Which finding is most characteristic of HELLP syndrome?

• A. Hemolysis with elevated liver enzymes and low platelets
• B. Hyperglycemia and obesity
• C. Hyperkalemia and hypertension
• D. Leukocytosis and thrombocytosis

Answer: (A)

HELLP syndrome is defined by a triad reflecting hemolysis, liver injury, and platelet consumption. Hemolysis occurs from microangiopathic processes that damage red blood cells, leading to anemia and characteristic blood smear findings. Elevated liver enzymes indicate hepatic involvement from this same vascular injury. Low platelets result from consumption in microthrombi, which raises the risk of bleeding and is a key diagnostic feature. When you see hemolysis, elevated liver enzymes, and a low platelet count together, HELLP is the best explanation. This condition usually arises in the late stages of pregnancy and is closely linked to preeclampsia, so signs like RUQ pain, nausea, and hypertension may accompany lab changes. The other options don’t fit because they describe metabolic or hematologic patterns that are not characteristic of HELLP—for example, hyperglycemia with obesity points to diabetes risk, abnormal potassium with hypertension isn’t defining for HELLP, and leukocytosis with thrombocytosis describes different inflammatory or reactive states rather than the platelet consumption seen in HELLP.
