Order TSH Blood Test - Thyroid-Stimulating Hormone TestThe thyroid-stimulating hormone (TSH) blood test measures the amount of TSH in the bloodstream. Produced by the pituitary gland, TSH signals the thyroid to release hormones that regulate metabolism, energy use, and many other bodily functions. Because TSH levels shift when thyroid activity changes, this test is a standard first step in evaluating thyroid function.
About TSH Blood Test - Thyroid-Stimulating Hormone Test in Oxnard
TSH is the pituitary gland's primary tool for managing thyroid output.
The pituitary gland releases TSH in response to the amount of thyroid hormone circulating in the blood. When thyroid hormone levels fall, TSH rises to prompt the thyroid to produce more; when thyroid hormone levels climb, TSH drops to reduce production. This feedback loop keeps thyroid activity within a narrow range.
A TSH result that is higher than the reference range often suggests an underactive thyroid, a condition known as hypothyroidism. A result below the reference range often suggests an overactive thyroid, or hyperthyroidism. However, TSH alone does not pinpoint the cause, and results are interpreted alongside symptoms, medical history, and sometimes additional tests such as free T4 or free T3.
TSH testing is used to investigate symptoms such as fatigue, weight changes, temperature sensitivity, and changes in heart rate. It may also be ordered to monitor thyroid function over time, including during treatment with thyroid medication. Reference ranges can vary by laboratory and by individual factors, so results are best discussed with a qualified healthcare professional.
