Our expert says:
You don't have to be fasting for thyroid tests and preferably you should do the test before taking your pill in the morning - always good to do TSH, T3 and T4
For Insulin resistance you should preferably be fasting for 12 hours - water is fine to use and it must be mentioned on your form that you are taking Eltroxin.
Cholesterol should also be done fasting for at least 12 hours , you can have a test called a LIPOGRAM where they test all the different fats in the body not just the cholesterol levels.
Ask your doctor to send you to a lab for:
Thyroid function tests
Fasting blood sugar and insulin levels
Go early in the morning and be fasting for 12 hours ( you may drink water)
