Thyroid antibody TSH - What is it?The blood test for antibody TSH determines whether there are antibodies against the TSH receptor of your thyroid gland. The thyroid gland 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.
What do we determine?
Blood: anti-TSHTSH 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.
TSH rises 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. Specifically, we look at antibodies that the body produces against the TSH receptor. We often see this in Graves' disease. The body then produces thyroid hormone uninhibitedly, because there is an imbalance in the feedback mechanism.
When to choose this test?Choose the Graves blood test when:
- You have already determined TSH and fT4 and these are abnormal.
