Thyroid Stimulating Hormone (TSH)
Thyroid Stimulating Hormone (TSH) is produced by the pituitary gland and regulates
the activity of the thyroid gland. TSH controls the release of thyroid hormones
thyroxine (T4) and triiodothyronine (T3), which influence metabolism, energy levels,
body temperature, and numerous physiological processes.
The TSH test is one of the most commonly used laboratory tests for evaluating thyroid function.

Clinical Significance
When thyroid hormone levels fall, the pituitary gland releases more TSH to stimulate
the thyroid gland. Conversely, when thyroid hormone levels are high, TSH production decreases.
Elevated TSH levels typically suggest hypothyroidism, while suppressed TSH levels may
indicate hyperthyroidism. Because of this feedback relationship, TSH testing provides
an early and sensitive indicator of thyroid dysfunction.
Who Might Benefit From This Test?
Individuals experiencing fatigue, unexplained weight change, mood disturbances,
hair loss, temperature intolerance, or menstrual irregularities may benefit from
TSH testing. It is also commonly used to monitor thyroid treatment or medication.
