  • Thyroid function testing should always be done under the following circumstances :

    1) First thing in the morning as early as possible, and definitely before 9am.

    2) Don't eat anything before the blood draw on the morning of the test, and don't drink anything except water. Avoid dehydration - it makes it harder to take blood and may affect some results.

    3) Don't take any thyroid meds or glandulars for 24 hours before the blood draw. Instead, wait until after the blood has been taken.
