I called the lab and they weren't sure smh so I decided to just be safe and not eat. I'm at the lab waiting now. I'm so thirsty.

So I'm reading so many different answers as to whether or not I need to fast. Some say no fasting but avoid carbs, some say fast for 8-12 hours, some say just eat normal. The doctor didn't explain anything when she told me to do the lab and when I later called the receptionist to ask she said not to eat or drink for 2 hours. I really want to eat my soup 😕
