Thyroid Levels

The LOUNA Thyroid Levels test package is designed for the monitoring of thyroid activity.

The Thyroid Levels test package includes two examinations: the concentration measurements of thyrotrophic hormone (TSH) and free thyroxine (T4-V). Regular monitoring of thyroid activity is advisable. It is particularly important when taking medication related to thyroid activity, or if the dose of the said medication has been altered.

The thyroid is a small organ located in the front of the throat that produces a hormone that affects the metabolism of the body – thyroxine. Thyroxine production can decrease or cease, which is called hypothyroidism. When the gland produces too much thyroxine, it is called hyperthyroidism.

The LOUNA Thyroid Levels package enables you to easily stay up to date on your thyroid levels.

Tests included


Thyroxine is an index of thyroid function (T4-V).

Thyrotropin is a hormone regulating the functions of the thyroid. The test is performed when a thyroid disorder is suspected.
