Therapeutic TSH levels for patients on thyroid hormone replacement are typically targeted to a narrower range (often between 0.5 and 3.0 mIU/L) to ensure optimal treatment, while screening values for the general population can be considered acceptable up to a higher threshold (around 4.5 to 5.0 mIU/L, not 10 as exaggerated in the option). This reflects the approach to more tightly control TSH within specific bounds for those being treated for thyroid disorders, compared to the broader range considered normal in the general population.
