Whisky: a new provacative test for calcitonin secretion.

Oral whisky is a potent stimulus of calcitonin secretion. Peak increments of immunoreactive calcitonin are observed within 15 min after the ingestion of 50 ml of whisky; the magnitude of the response is similar to that observed during a four-hour calcium infusion. This procedure has several advantages over standard methods of stimulating calcitonin release in patients at risk of developing medullary carcinoma of the thyroid, and this is shown by a study in a large family with familial chromaffinomatosis.
