Write answer in between .Q:A 60-year-old man is admitted to the ER for a severe persistent abdominal pain of 6 hours duration with nausea, vomiting, and steatorrhea. His medical history is relevant for multiple similar episodes of abdominal pain, hypertension, a recent fasting plasma glucose test of 150 mgdL, and an HbA1c of 7.8. His temperature is 37C 98.6F, respirations are 15min, pulse is 67min, and blood pressure is 12298 mm Hg. Physical examination is positive for epigastric tenderness. A computed tomography of the abdomen of the patient is shown in the picture. Which of the following laboratory results is most specific for this patients condition?? A: Elevated amylase, elevated lipase, B: Low serum trypsin, low stool elastase, C: Elevated ALT, elevated gamma-glutamyl transpeptidase, D: High serum trypsin, high stool elastase, E: Elevated alkaline phosphatase, elevated total bilirubin,  <response>: Based on the information provided in the question stem, this patient is a 60-year-old man with a history of recurrent abdominal pain, steatorrhea, hypertension, impaired fasting glucoseprediabetes, and elevated HbA1c. The description of the abdominal pain, nausea, vomiting and steatorrhea point towards a diagnosis of chronic pancreatitis. The CT image shows calcifications in the pancreas, which is consistent with chronic pancreatitis. The lab results that would be most specific for chronic pancreatitis would show decreased pancreatic exocrine function. Choice B shows low serum trypsin and low stool elastase, which are markers of exocrine pancreatic insufficiency seen in chronic pancreatitis. Choices A, C, D, and E may be seen in other abdominal pathologies and are less specific for chronic pancreatitis.B: Low serum trypsin, low stool elastase
