Thyroid blood test - What is it?
The thyroid blood test determines your thyroid hormones. The thyroid is a gland in the neck area. Due to the secretion of hormones The thyroid gland has many functions, such as metabolism in the body.After releasing a hormone from the brain, the thyroid gland will produce various thyroid hormones. We measure the most important of these in the blood test.
Please note, the TSH is determined. If different, then also the fT4. If you want to receive the fT4 in all cases, please indicate after your order.
What do we determine?
Blood: TSH
TSH stands for thyroid stimulating hormone. TSH is a hormone from the brain. It has an effect on the thyroid gland. When TSH comes into contact with the thyroid gland, it turns on the production of FT3 and FT4. These are the hormones that the thyroid gland releases. These hormones play an important role in the body's metabolism, especially FT3.TSH increases during stressful moments in life, but also during moments of development of the body. TSH from the pituitary gland is stimulated by yet another hormone from the brain. It is actually inhibited by FT3 and FT4. It is therefore important to also determine this thyroid hormone, especially FT4, to determine thyroid diagnoses. However, when the TSH is normal, it is actually unnecessary to test the fT4. That is why we normally only test the fT4 with abnormal TSH values. If you would like to know both at the same time, please let us know.
Blood: FT4 (thyroxine)
FT4 or T4 or thyroxine are all names for the same hormone in different stages (the F stands for free). FT4 consists of, among other things, iodine (which is found in salt) and therefore plays an important role in the body's metabolism. FT4 is more common than FT3 in a 14:1 ratio. Through the blood test for this thyroid hormone in combination with the TSH determination, we can make a statement about the health of your thyroid gland.Fasting test?

Mutual acceptance may not always be present due to potentially reduced reliability with a capillary sample.

If necessary, the doctor can call to ask about physical abnormalities. You don't have to interpret the results yourself because there is always advice and explanation from the doctor.
