TSH (Thyroid Stimulating Hormone)
What does TSH (Thyroid Stimulating Hormone) measure?
The TSH test measures the level of thyroid-stimulating hormone, a hormone that helps regulate thyroid gland activity. It may be used to assess thyroid function and to help evaluate symptoms that may be associated with an underactive or overactive thyroid, such as changes in energy, weight, heart rate, or temperature tolerance. It may also be used to monitor known thyroid conditions or response to treatment.
