can i drink water before thyroid test

Of course, I'm here to assist you with your question. For most standard thyroid blood tests, such as TSH, T3, and T4, drinking water beforehand is generally fine and does not affect the results. It’s important to stay hydrated.

That's correct, just water. You should avoid caffeine-containing beverages like coffee or tea before your test, as they can potentially influence the results or interact with thyroid medication absorption if you're taking any.
