WHAT BLOOD TESTS ARE THERE TO TEST IF THE THYROID IS WORKING? TSH: Testing TSH is the best way to initially check thyroid function. A high TSH level indicates that the thyroid hormone level is low (usually hypothyroidism). A low TSH usually means that there is too much thyroid hormone.

14 Σεπ 2023 · Thyroid function tests are blood tests which help to check the function of your thyroid gland. They are mainly used to detect an underactive thyroid gland (hypothyroidism) and an overactive thyroid gland (hyperthyroidism).
Thyroid function tests are designed to distinguish hyperthyroidism and hypothyroidism from the euthyroid state. To accomplish this task, direct measurements of the serum concentration of the two thyroid hormones—triiodothyronine (T3) and tetraiodothyronine (T4)—more commonly known as thyroxine, are extensively employed.
What are thyroid function tests? The usual blood tests done for thyroid function are TSH, T4 and sometimes T3. In most cases, your TSH level will be the first hormone to be measured, because if this is normal, it is very likely that your thyroid is functioning normally.
TESTS HOW DOES THE THYROID GLAND FUNCTION? The major thyroid hormone secreted by the thyroid gland is thyroxine, also called T4 because it contains four iodine atoms. To exert its effects, T4 is converted to. Blood tests to measure these hormones are readily available and widely used, but not all are useful in all situations.
