Frequently Asked Questions (FAQ's):
1. What does the TSH test measure?
It measures the amount of thyroid-stimulating hormone produced by the pituitary gland, which controls the thyroids release of T3 and T4 hormones.
2. Why is TSH the preferred initial test for thyroid health?
Because TSH changes are highly sensitive—indicating thyroid dysfunction early—even before T3 and T4 levels become abnormal.
3. What do high TSH results mean?
High TSH usually indicates hypothyroidism—meaning the thyroid is underactive. Your doctor may also check T4 levels to confirm the diagnosis and determine its severity.
4. What do low TSH results indicate?
Low TSH typically points to hyperthyroidism—where the thyroid is overactive. In such cases, additional tests like T3 and T4 are used to pinpoint the cause.
5. Do I need to prepare or fast for the TSH test?
No, the TSH test requires no special preparation or fasting. A standard blood sample is all that’s needed.
6. How is TSH used to manage thyroid medication?
Doctors use TSH levels to adjust thyroid medication dosages—such as levothyroxine—to ensure hormone levels stay within the optimal range. Regular testing helps maintain balance.
