Whipple's Triad

Whipple's triad is a collection of three criteria (called Whipple's criteria) that suggest a patient's symptoms result from hypoglycemia which may indicate insulinoma. The triad is stated in various versions, but the essential conditions are:

1. Symptoms known or likely to be caused by hypoglycemia
2. A low plasma glucose measured at the time of the symptoms
3. Relief of symptoms when the glucose is raised to normal
