This measures the amount of TSH in the blood. The role of TSH is to stimulate the thyroid gland to produce and release T4 and T3. A high TSH result may mean an underactive thyroid and a low TSH result can indicate an overactive thyroid, however a TSH result should be used in conjunction with other thyroid markers to understand why an excess or deficiency of the hormone is present.
This test measures the amount of T4 in the blood, which is not attached to a specific protein. This free hormone is thought to be responsible for all the thyroid hormone effects in the body. If present with clinical symptoms a high FT4 result may indicate an overactive thyroid, known as hyperthyroidism and a low FT4 result may indicate an underactive thyroid, known as hypothyroidism.
T3 is the active form of the thyroid hormone, thyroxine. 99.7% of T3 is bound to a protein in the blood, the rest is unattached or ‘free’. This test measures the amount of free T3 in the blood. A high FT3 result may indicate an overactive thyroid, known as hyperthyroidism.
TPOAb and TGAb are antibodies, measuring the presence and quantity of these can identify the presence of autoimmune thyroid disease. Mild to moderate levels of thyroid antibodies can be found in a number of autoimmune conditions such as type 1 diabetes, pernicious anaemia, rheumatoid arthritis and SLE. Significantly elevated levels can indicate thyroid autoimmune diseases.
