The English word clown is first recorded c. 1560 (as clowne, cloyne) in the generic meaning rustic, boor, peasant. The origin of the word is uncertain, perhaps from a Scandinavian word cognate with clumsy. It is in this sense that Clown is used as the name of fool characters in Shakespeare's Othello and The Winter's Tale.
Fast for eight to 12 hours before you have your first blood taken. The glucose tolerance test includes a blood draw before you drink a sugary liquid, and an hour after that as well. If you're doing a three-hour glucose tolerance test, then it's one blood draw every hour for three hours. Select your first meal after the fast carefully.
So look on your lab sheet to check and see which blood tests they will be doing and then call the lab to see if there is a requirement to fast before doing any of them. Ask them your question about how long to fast. When I did A1c years ago, there was a 12 hour fast before hand as I recall.
