Suppost too because you get a free metabolic panel with it and that makes your AIC fasted blood glucose levels accurate but if you only care about the hormone reading them doesn't matter
I always draw blood before 9am....I always fast...every time no matter what I'm testing
That way all my results are consistent and I never have to try and think back to if I was fasting for a particular test
It's a big pluse when you are old and senile like me
