TSH stands for thyroid stimulation. hormone TSH field test is a blood test to determine this hormone Very high or very low TSH levels can be a symptom of a thyroid problem.
The thyroid gland is a small butterfly-shaped gland located in the front of your neck. Your thyroid gland does what hormones He arranges how your body uses energy. The thyroid gland hormones affect almost every organ in your body, including your heart. They help control your weight, body temperature, muscle strength, and your mood. If you have little or no thyroid. hormones In your blood, almost every function of your body is delayed. In very large amounts, almost every body function is accelerated.
The thyroid gland is controlled by the pituitary gland in the brain. The pituitary gland turns on the thyroid gland (TSH). hormone (TSH), which reports to the thyroid gland the amount of thyroid gland hormone it needs to make.
If the thyroid hormone If the level in the blood is very low, the pituitary gland makes more TSH, telling the thyroid gland it should work harder. If the thyroid gland hormone levels are very high, the pituitary gland literally does not cook. By measuring TTH levels in the blood, one can see if the thyroid gland creates the proper levels. of hormones .
Other name: Thyroid Stimulation Test
What is it used for?
The TSH test is used to determine how well the thyroid gland functions. It can tell if you have hyperthyroidism (too many thyroid glands. hormone ) or hypothyroidism (too little thyroid gland hormone ) in your blood. However, the TSH test cannot demonstrate and thyroid gland is caused.
If you take a thyroid recipe. hormone Hypothyroidism or medication due to removal of the thyroid gland, a TSH test will be done systematically to find the value of the thyroid gland. hormone TSH test is still used in thyroid prognosis. hormone Levels after hyperthyroidism are cured.
Why is the TSH test necessary?
A TSH test may be necessary if there are signs of a very high or very active thyroid gland hormone in your blood.
Hyperthyroidism (too much thyroid. hormone ) Also called overactive thyroid. The presence of more thyroid hormones than necessary, speeds up the body’s functions and causes signs such as
- Weight loss involving more than normal
- Fast or irregular heartbeat
- Nervousness or irritability
- Sleep problems, fatigue
- Griping, muscle weakness
- Sweating
- Frequent defecation (much pooping)
- KROP (enlarged thyroid gland)
Hypothyroidism (too little thyroid. hormone Hypothyroidism (too little thyroid gland.) Also called Unideal Specialty. Too little thyroid. hormone Slows down your body’s functions and causes, among other things, the following symptoms
- Fatigue
- Weight gain
- Increased sensitivity to cold
- Joint and muscle pain
- Dry skin
- Dry, thinning hair
- Heavy or irregular menstruation

- Constipation
You may undergo a TSH test along with other tests to diagnose abnormal nodules or bumps in the thyroid gland that are likely to be thyroid cancer or thyroid nodules.
What happens during the TSH test?
The health professional will take a blood sample from a vein in your arm with a small needle. After the needle is inserted, a small amount of blood is collected in a test tube or bottle. Some pressure can be felt as the needle goes in and out. This usually takes less than 5 minutes.
Do I need to prepare anything for the test?
No special substances are needed for the TSH blood test. If your caregiver has ordered other blood tests, you may need to fast (not eat or drink) for a few hours for the test. Your doctor will tell you if you should follow any special instructions.
Were there any risks associated with the test?
There are no sufficient risks associated with blood testing. You can have slight soreness and bruising in the area where the needle is inserted, but most signs disappear quickly.
What do the results mean?
The results of a TSH test can indicate that the thyroid gland produces very large amounts or very little thyroid. However, the test cannot tell you why your TSH level is very high or very low.
If the test results are not normal, the physician will probably perform other blood tests on the thyroid gland to find the cause of the thyroid problem. These blood tests may include the following possibilities.
- T4 thyroid hormone test
- T3 thyroid hormone test
- For example, thyroid antibody tests can help diagnose autoimmune thyroid disease:
- Grave’s disease, increasing the underlying cause of hyperthyroidism.
- Hashimoto’s disease, a common underlying cause of hypothyroidism.
In some cases, an abnormal TTH result can be a symptom of a pituitary problem, but this is not often the case.
Is there anything else I should know about the TSH test?
TSH levels may be high or low even if the thyroid gland is not diseased. Unusual diseases unrelated to the thyroid gland can lead to lower TTH levels in the short term. TTH levels may also be higher in persons over 80 years of age even in the absence of thyroid problems.
Pregnancy still affects the degree of TTG. In many cases, it is somewhat lower in the direction of the first trimester. However, thyroid disease can also occur during pregnancy. If you develop thyroid disease during pregnancy, your doctor will keep a close eye on your condition throughout your pregnancy and after the birth of your baby. This is due to the fact that hyperthyroidism, and less frequently hypothyroidism, may continue to be present later in the family. If you have thyroid problems, you should consult your own physician when you are pregnant or think you are pregnant.
Newborn babies are routinely screened with the TSH test to see if they are born with hypothyroidism (congenital hypothyroidism)
