how many hours fasting for blood test - #23539

Sia

I am really confused about how many hours fasting for blood test is needed. Last week, when I went for my routine check-up, the nurse mentioned I should fast before some tests, but she didn’t say for how long! I thought I could just skip breakfast and go in, but I later read that it’s a longer period. I was fasting for like 6 hours since I ate dinner late the night before. I had my meal around 10 PM, and I got there at 4 AM, so I thought that should cover it? But now I'm worried that maybe I didn’t fast long enough. My friend who did it said she fasted for 12 hours for her blood test, and that worried me even more. I mean, do I really have to fast for so many hours before a blood test to get accurate results? If I don’t, are my results gonna be all wonky? Should I just keep trying to follow the instructions better next time even if the nurse didn’t specify how many hours fasting for blood test was needed? I feel pretty lost and could really use some clarity on this! How do I make sure I’m doing it right for the next one?
