No. A physician must specifically order thyroid function tests, such as a T4 and TSH. (Other specific thyroid tests may be ordered, as well.)
Marijuana use can potentially affect thyroid function tests, including TSH levels, by temporarily altering hormone levels. However, more research is needed to fully understand the impact of marijuana on thyroid function. If you are concerned about how marijuana use may be affecting your health, it is best to consult with a healthcare provider.
Yes, taking thyroxine before a blood test can affect the results, particularly thyroid function tests. Thyroxine, a medication used to treat hypothyroidism, influences levels of thyroid hormones in the bloodstream, which may lead to altered test outcomes. It's important to follow your healthcare provider's instructions regarding medication timing before any lab tests to ensure accurate results.
