@stuckonu I don't believe there are any medical doctors who answer questions on here. One of the sites I have used in the past is https://labtestsonline.org/
If you look there, you might find answers to your questions. Do you know ahead of time when your tests might be pulled, so you can fast if needed? I have found that a dr might say fasting is not needed. And I usually will ask the phlebotomist if fasting is required for a particular test, or not.
