At what TSH level do you treat hyperthyroidism?

Can you have normal TSH levels but still be hyperthyroid?

A TSH level lower than normal indicates there is usually more than enough thyroid hormone in the body and may indicate hyperthyroidism. When hyperthyroidism develops, free thyroxine (T4) and free triiodothyronine (T3) levels rise above normal.

What is a critical TSH level?

The standard reference range for the TSH level is anywhere between 0.30 and 5.0 uIU/mL. If your TSH level is higher than 5.0 uIU/mL, then the lab will flag you as “high,” and you may experience the symptoms listed above 5.0 uIU/mL. Values of the TSH level more than 10.0 uIU/mL need long-term thyroid supplements.

What blood levels indicate hyperthyroidism?

Normal test range for an adult: 0.40 – 4.50 mIU/mL (milli-international units per liter of blood). T4: thyroxine tests for hypothyroidism and hyperthyroidism, and used to monitor treatment of thyroid disorders. Low T4 is seen with hypothyroidism, whereas high T4 levels may indicate hyperthyroidism.

Does hyperthyroidism always show in a blood test?

Thus, the diagnosis of hyperthyroidism is nearly always associated with a low (suppressed) TSH level. If the TSH levels are not low, then other tests must be run. Thyroid hormones themselves (T3, T4) will be increased. For a patient to have hyperthyroidism, they must have high thyroid hormone levels.

Is TSH test enough to diagnose hyperthyroidism?

TSH alone would be a sufficient screening test for thyroid hormone abnormalities. Thyroid problems are common in adults. There are different recommendations on how to screen for abnormal thyroid hormone levels that may indicate a thyroid problem, and therefore, there are many variations in how this is done.
