Thyroid Related Thyroid related blood testing
TSH (thyroid stimulating hormone) is a hormone manufactured in the pituitary gland (found in the brain). It s role is to stimulate thyroxine production in the thyroid gland (found in the neck). A high level within a health screening is associated with an underactive thyroid gland (hypothyroidism) and a low level is found if the thyroid gland is over-active (hyperthyroidism). Changes in the TSH level alone can indicate underlying thyroid problems even if the thyroxine levels are normal.

Free T4 (free thyroxine) is the active form of thyroxine, released from the thyroid gland in the neck. Its role is to control metabolism - release of energy from all cells of the body. A lack of thyroxine leads to, for example, tiredness and weight gain, whereas an excess will lead to weight loss, rapid heart rate and anxiety. It is generally believed that this level (FT4) is the most reliable indicator of thyroid status - ie whether the gland is over-active (hyperthyroidism) or underactive (hypothyroidism).

Free T3 (Free Triiodothyronine) - This is one of two hormones produced by the thyroid gland. This measures the level of T3 that is 'free' and is able to regulate metabolism. Symptoms Hyperthyroid symptoms Weight loss with increased appetite
