    The Thyroid Stimulating Hormone (TSH) Test is for testing Thyroid Stimulating Hormone (TSH) in the blood. 

      Thyroid-stimulating hormone (TSH) is produced by the pituitary and acts on the thyroid gland to stimulate the production of thyroxine (T4). Higher than normal TSH can indicate a disorder of the thyroid gland, while low TSH can indicate overproduction of T4, which acts in negative feedback on the pituitary to reduce TSH production. Low TSH can also be caused by problems in the pituitary gland itself, which result in insufficient TSH being produced to stimulate the thyroid (secondary hypothyroidism). Thyroid disease or dysfunction is notoriously underdiagnosed.

      Overt hypothyroidism, with its characteristically high TSH and low circulating T4 levels, or hyperthyroidism, with low TSH and high T4 levels (most commonly manifested as Graves’ Disease), are relatively easy to recognize clinically. But an elevated TSH associated with normal thyroid hormone levels, defined as “subclinical” hypothyroidism, is thought to be present in 4-10% of the general population and in up to 20% of women over 60 years old, while a low TSH and normal thyroid hormone levels, or subclinical hyperthyroidism, occurs in about 2% of the population. Reference range levels of TSH are between 0.5 and 3.0 µU/mL (optimum 0.5—2.0 µU/mL).

      Thyroid disease is common in women often under the age of 40. It tends to run in families. You may need a Thyroid Stimulating Hormone Test if a family member has ever had thyroid disease or if you have symptoms of having too much thyroid hormone in your blood.

      Common symptoms include:

      • Tiredness
      • Being sensitive to cold
      • Weight gain
      • Constipation
      • Depression
      • Slow movements and thoughts
      • Muscle aches and weakness
      • Muscle cramps
