Quick answer
The TSH Blood Test measures thyroid-stimulating hormone in the blood. TSH is made by the pituitary gland and tells the thyroid how much hormone to produce. Because it responds to thyroid hormone levels, it is a sensitive first step when thyroid function is in question. Results are interpreted by a qualified healthcare provider.
What this test measures
The thyroid gland sits in the neck and produces hormones that influence metabolism, energy, heart rate, and body temperature. The pituitary gland monitors those hormone levels and adjusts TSH output to keep them in range. When thyroid hormone falls, TSH usually rises; when thyroid hormone is high, TSH usually falls.
The test requires a blood sample from a vein. TSH is often ordered together with free T4 and sometimes free T3 to build a complete picture of thyroid function. Because TSH changes slowly, a single result is usually interpreted alongside the person's symptoms and any previous thyroid results.
Clinicians request TSH testing to investigate fatigue, weight change, temperature sensitivity, palpitations, or other symptoms that could relate to the thyroid. It is also used to monitor people taking thyroid medication and to follow known thyroid conditions over time. The result alone does not diagnose a condition.
