so sorry I’ve searched and can’t find the recommendation for when to take last dose of NDT before blood tests. My test is at 09:20 … I usually take one at bedtime and one when I wake… shall I just miss the one when I wake? I’ve looked at pinned posts but can’t find the info… thanks so much

yes correct

Last dose NDT should be 8-12 hours before test

What vitamin supplements are you currently taking

Remember to stop any supplements that contain biotin 3-5 days before test as biotin can falsely affect test results
