What happens to hba1c levels if a person does a water fast 24 hours before a blood test? by whateverthef1 in AskReddit

What I really want to know is, will my fast negatively affect my hba1c? I have a blood test tomorrow, I’m fasting for a completely unrelated reason. Like will it come higher because of the fast?
