What is a TSH (Thyroid Stimulating Hormone)?
The thyroid-stimulating hormone (TSH) level in blood is a gauge doctors use to determine thyroid health. If a patient is gaining or losing weight unexpectedly or suffering from fertility problems, TSH levels may be abnormal and this could be a sign of hyperthyroidism or hypothyroidism. TSH levels can be measured as part of a series of blood tests that may or may not include free thyroxine and total thyroxine tests. If TSH levels are abnormal, doctors will order thyroxine blood tests. In many cases, all three tests are ordered at the same time.
