LABS: When is the best time of the menstrual cycle to pull labs? Does it matter for all panels or just the hormone panel?

The best time to pull labs (specifically the hormone panel) is around days 19-21 of your cycle before you get an estrogen surge! If you are doing one of the other tests you don’t have to worry about this as much, but generally you want to always pull on the same day of your cycle to get accurate data points.
