How much time do you have to fast for?

For a blood test?: Assuming you’re referring to fasting prior to a blood test, your best bet would be to go for your blood test first thing in the morning before eating anything. If that’s impractical, then fasting 8-12 hours prior to a blood test later in the day should suffice.
