Temperature is 38.3°C (100.9°F), blood pressure is 138/80 mmHg, and pulse is 85/min. Laboratory studies reveal an alkaline phosphatase of 415 U/L (reference range: 20-70 U/L) and total bilirubin of 4.1 mg/dL (reference range: 0.1-1.0 mg/dL). Both liver biopsy and serum tests for Echinococcus granulosus are negative. A stool sample is collected and found to contain several eggs.
