I have a blood test tomorrow how long do I need to fast for?!


Question: I have a blood test tomorrow how long do I need to fast for.?
I am getting a HIV/STI test and a diabetes blood test tomorrow, since you can't make appointments they wouldn't really give me a clear idea of how long I had to not eat for (or it could be because I was talking to the receptionist).
It is almost 7 PM now and I have stopped eating and I plan to go in at 7 AM is that long enough.?Health Question & Answer
