Question

Quizplus · Accepted Answer

The glucose tolerance test usually requires a 10-hour overnight fast. This allows for accurate measurements of blood glucose levels and insulin response to glucose ingestion. A 5-hour fast may not provide enough time for the body to fully clear glucose from the system, while a 24 or 48-hour fast would be excessive and potentially dangerous.
