What is a thyroid stimulating hormone blood test?
The pituitary gland produces Thyroid Stimulating Hormone (TSH) to instruct the thyroid gland to produce hormones T3 and T4, which regulate metabolic function, growth, and weight. Higher TSH concentrations indicate lower thyroid function, whereas lower TSH concentrations suggest an overactive thyroid gland.
The TSH blood test is used to evaluate thyroid gland function and to help diagnose thyroid disorders. If the thyroid gland is not producing enough T3 and T4, the pituitary gland produces more TSH to stimulate the thyroid gland, resulting in a higher TSH level in the blood. Conversely, if the thyroid gland is producing too much T3 and T4, the pituitary gland produces less TSH, resulting in a lower TSH level in the blood.
A TSH blood test will help determine what you are experiencing. It can also be used to monitor thyroid hormone replacement therapy in people with confirmed hypothyroidism.
