The Lundh test in the diagnosis of pancreatic disease: a review of five years' experience.

An analysis of 523 Lundh tests performed on 492 patients over a five-year period has been made. The results suggest that the test is a simple, cheap, and reliable procedure for the diagnosis of pancreatic exocrine insufficiency, and is suitable for both specialized units and general hospitals. It is particularly useful in the differential diagnosis of patients with steatorrhoea or obstructive jaundice and can often distinguish between malignant and benign lesions, as well as indicating the site of the obstruction. It is of lesser value in the diagnosis of abdominal pain.
