Should I skip on the benzos tomorrow morning? I don't want to bleed out if it thins your blood or messes with the test.
Benzodiazepines (BZDs) aren't blood thinners. Many antidepressants are, but you won't bleed to death when taking them either unless the wound is huge. Nor, afaik, do BZDs affect thyroid blood tests. Their affect on thyroid function is tiny.
