Which laboratory result would indicate a preeclampsia feature that requires delivery assessment?

• A. Platelet 180,000/µL
• B. Platelet 90,000/µL
• C. AST/ALT normal
• D. Creatinine 0.8

Answer: (B)

In preeclampsia, certain lab abnormalities signal more severe disease and prompt consideration of delivery. A platelet count of 90,000/µL shows thrombocytopenia, which is a severe feature of preeclampsia (and can indicate potential HELLP syndrome). This level raises the risk for maternal bleeding and worsening condition, so it triggers delivery assessment. The other values are normal and do not indicate severe disease requiring delivery planning: a platelet count of 180,000/µL is within normal limits, normal AST/ALT means no evident liver involvement, and a creatinine of 0.8 mg/dL indicates preserved renal function. Thus, the platelet count of 90,000/µL is the finding that necessitates delivery assessment.
