An entry-level test for thyroid function, which measures the amount of thyroid stimulating hormone (TSH) in the blood.
Thyroid stimulating hormone (TSH) is produced by the pituitary gland to regulate the production of thyroid hormones thyroxine (T4) and triiodothyronine (T3). It is produced in response to levels of circulating hormones. Raised levels of TSH can indicate that the thyroid is struggling to produce sufficient quantities of thyroid hormones and is underactive, whereas low levels can indicate that the thyroid is producing excess levels of thyroid hormones and is overactive.
This test is ideal for anyone looking to monitor their thyroid function.
Signs of low level TSH can include tiredness, poor tolerance to cold temperatures, constipation, carpal tunnel syndrome (a painful condition of the hand and fingers), a deepening of the voice, depression and irregular periods.
High levels of TSH meanwhile can present themselves as insomnia, hand tremors, frequent bowel movements, weight loss and feeling hot in cold temperatures.
Thyroid Stimulating Hormone is produced in the pituitary gland and stimulates the thyroid gland to produce thyroid hormones thyroxine (T4) and triiodothyronine (T3).
High levels of TSH indicate an underactive thyroid while low levels indicate an overactive thyroid. In primary pituitary failure, a low TSH will be associated with an underactive thyroid.
