BOF: 3.98

A consultant anaesthetist is about to induce a 68 year old male for an elective total knee replacement when he notices that on the blood tests done in the morning of the operation all are normal apart from a serum amylase of 570U/L (0-100).

There is no history of abdominal pain. The serum amylase was requested inadvertently by a new junior doctor.

Other biochemistry results are normal with normal urea and electrolytes but a high amylase has been noted previously but the patient had not had abdominal pain at that time either.

The anaesthetist refuses to induce the patient and requests an urgent abdominal ultrasound scan which is normal.

What is the likely cause of the high amylase in this patient?

a)      Macroamylase

b)      Undetected pancreatitis

c)      Renal failure

d)      Contamination of the blood sample

e)      Duodenal perforation
