Order TSH Blood Test - Thyroid-Stimulating Hormone TestThe thyroid-stimulating hormone (TSH) blood test measures the amount of TSH in the bloodstream. Because TSH is produced by the pituitary gland to regulate thyroid activity, its level offers a sensitive indicator of how well the thyroid is functioning.
About TSH Blood Test - Thyroid-Stimulating Hormone Test in Orchards
TSH acts as the pituitary gland's signal to the thyroid, instructing it to produce and release the hormones thyroxine (T4) and triiodothyronine (T3).
When thyroid hormone levels fall, the pituitary releases more TSH to stimulate the thyroid; when thyroid hormone levels rise, the pituitary releases less. This feedback loop means that an elevated TSH often points toward an underactive thyroid, while a reduced TSH can suggest an overactive thyroid.
The test is commonly used to screen for thyroid dysfunction and to help evaluate symptoms such as fatigue, weight changes, temperature sensitivity, and changes in heart rate. It may also be ordered to monitor the effect of thyroid-related treatment over time.
Results are typically interpreted alongside the person's clinical picture and, when needed, additional tests such as free T4 or T3. A single value outside the reference range does not by itself diagnose a condition, and laboratory reference ranges can vary.
