A 41 year old African American woman presents with abdominal pain, jaundice and dark urine for 3 days. She had experienced several bouts of vomiting since the previous day.
On the day her symptoms began, she had a dish of broad beans for breakfast.
Her medical and family histories are unremarkable. She underwent cholecystectomy at the age of 38. Her travel history is significant for a trip to Congo 5 months ago, where she stayed for 2 weeks.
Currently she is not on any medication. She only drinks socially, and does not have a history of IV drug abuse or sexual promiscuity.
