What Does the TSH Test Measure?

TSH, or Thyroid Stimulating Hormone, is a hormone produced by the pituitary gland in the brain. Its job is to tell the thyroid gland to make more of its hormones, which are essential for controlling body temperature, metabolism, and heart rate, among other functions. When TSH detects the thyroid is not producing enough hormones, it triggers the production of more. Too much or too little TSH can indicate an imbalance in how your thyroid is functioning.

How to Interpret TSH Test Results

The results of a TSH test will provide your doctor with an indication of how much TSH is in your body. A normal TSH test result can range from 0.4 to 4.0 milli-international units (mIU) per liter of blood. Results above 4.0 mIU/L may indicate an underactive thyroid or hypothyroidism, while results below 0.4 mIU/L may indicate an overactive or hyperthyroidism. In addition, results between 0.4 and 4.0 mIU/L may indicate a healthy thyroid.

Is Additional Testing Needed?

Your doctor likely will order additional thyroid tests if your TSH test results are not within the normal range. These tests may include the Thyroid Stimulating Hormone Receptor Antibody Test, T3 and T4 tests, and thyroid sonography. These tests will confirm the diagnosis of an overactive or underactive thyroid and allow your doctor to create a treatment plan to address your imbalance.
