Do you have to be fasted for accurate blood test results?
-
Got my blood work perscription from Marek Health but I won't have time really to go and get my blood drawn at my local lab. Busy week with work, will going unfasted hinder my results?
Getting the following tested:
- Testosterone
- TSH
- Iron
- Prolactin
-
For those tests, no. But if you're testing testosterone you should do it first thing in the morning. Certainly before 9am.
Also avoid any biotin supplementation a few days before.

Looks like testosterone drops quite a bit after eating.
