Thyroid-Stimulating Hormone Test
A thyroid-stimulating hormone test determines the level of TSH in your blood. This is a hormone that is generated by the pituitary gland and plays a role in controlling the hormonal levels produced by your thyroid. With this test, your doctor can find out the presence of any hormonal issues that can affect the overall levels of sodium in the body, such as hypothyroidism and hyperthyroidism. It does not require any special preparation for the thyroid-stimulating hormone test, but make sure to ask your doctor for stopping some drugs before starting. [5]
