The blood test

Measurement of the thyroid-stimulating hormone

The thyroid function can be assessed with a blood test. First the level of the hormone TSH (thyroid-stimulating hormone) is measured. TSH is produced in the pituitary gland and controls the thyroid function by stimulating your thyroid gland in the formation and release of hormones.
 
If large amounts of thyroid hormones are in the blood, usually the pituitary gland then releases less TSH to slow down the formation of hormones in the thyroid gland. On the other hand, if the amount of thyroid hormones in the blood decreases, the pituitary gland releases more TSH to stimulate hormone production in the thyroid gland.
 
An abnormally high TSH level is therefore usually an important indicator of an underactive thyroid. A low TSH level, however, is usually a sign of an overactive thyroid.

Verification of the thyroid hormones

If the TSH value is abnormal, then the values of the thyroid hormones "free T3” (triiodothyronine) and "free T4" (thyroxine) are designed to detect whether it is a slight error or whether a strong thyroid dysfunction exists.
 
If there is suspicion of a chronic thyroiditis, then also the presence/absence of certain thyroid antibodies in the blood is confirmed.
