TSHwaarde

TSHwaarde is a Dutch term that translates to "TSH value" in English. TSH stands for Thyroid Stimulating Hormone. This hormone is produced by the pituitary gland, a small gland located at the base of the brain. The primary function of TSH is to stimulate the thyroid gland, located in the neck, to produce thyroid hormones, namely thyroxine (T4) and triiodothyronine (T3). These thyroid hormones are crucial for regulating metabolism, growth, and development in the body.

A TSH blood test is a common diagnostic tool used by healthcare professionals to evaluate thyroid function. The TSH level in the blood can indicate whether the thyroid gland is overactive (hyperthyroidism) or underactive (hypothyroidism). Elevated TSH levels typically suggest that the thyroid gland is not producing enough thyroid hormones, prompting the pituitary gland to release more TSH to stimulate it. Conversely, low TSH levels often indicate that the thyroid gland is producing too much thyroid hormone, and the pituitary gland is suppressing TSH production.

Normal TSH ranges can vary slightly depending on the laboratory and the individual's age and other factors. However, typical reference ranges are generally between 0.4 and 4.0 milli-international units per liter (mIU/L). Deviations from this range, whether high or low, warrant further investigation by a doctor to determine the underlying cause and appropriate treatment. Doctors may also order tests for T4 and T3 levels in conjunction with TSH to get a more comprehensive picture of thyroid health.
