A high level of thyroid stimulating hormones indicates that the thyroid gland is failing due to hypothyroidism or an underactive thyroid gland. The thyroid gland produces thyroid hormones responsible for metabolism in the body. In hypothyroidism, the thyroid gland fails to produce enough thyroid hormones needed by the body.
Collect your sample, mail it back in the prepaid envelope, and receive results by email or phone.
If the thyroid stimulating hormones are low, this indicates that an individual is suffering from hyperthyroidism or an overactive thyroid gland. In this case, the thyroid gland produces thyroid hormones more than what the body needs. If an individual has a normal level of thyroid stimulating hormones in the body, this means that the thyroid gland functions normally.
Thyroid Blood Test
Thyroid blood tests are one of the tests conducted in an individual to gauge the thyroid stimulating hormones in the body. This test shows imbalances that often go undetected with other limited assessments. This test is not only able to determine hyperthyroidism and hypothyroidism. It may also point into sub-clinical manifestation of other thyroid dysfunctions. Thyroid blood tests are done to assess the following:
- Anti-thyroglobulin antibodies (anti-TG)
- Hypersensitive stimulating hormones (TSH)
- Free thyroxine (T4)
- Free triiodothyronine (T3)
The blood sample is then sent to the laboratory for analysis. After which, a diagnosis can then be given to an individual for him to know which thyroid disorder he is suffering from.
Thyroid Test Ranges
The validity of a thyroid stimulating hormone test lies on the reference range. After one submits himself for a thyroid test, test results will then be compared and assessed with the normal thyroid hormone range. If test result fall under or above normal hormone range, it then shows that an individual is suffering from a thyroid disorder. When the thyroid gland is dysfunctional, numerous problems may arise. Some people will then feel symptoms leading to hyperthyroidism, hypothyroidism or worst, thyroid cancer. With the help of thyroid tests, a physician will be able to diagnose which thyroid disorder an individual may be suffering from, thus a treatment and medication will be provided.
Thyroid Test T4
There are two types of T4 tests. Total T4 test and free T4 test. These tests help physicians evaluate the thyroid function. Total T4 test is used to diagnose hypothyroidism and hyperthyroidism. This is a very useful test but protein level in the blood may affect this test. With this common problem being encountered once total T4 test is done, free T4 test has replaced the latter. Free T4 test is not affected by protein levels in the body, thus providing a more accurate result and diagnosis.
Thyroid Test Results
Thyroid test results are provided after blood samples are assessed in the laboratory. Thyroid test results are then compared to the normal hormone range needed in the body. If thyroid test results show a high level or low level of hormone results, a diagnosis will then be provided. With this, a physician will then talk to the patient and inform him of his thyroid disorder. Proper treatment and medication will then be given to cure the thyroid disorder. Treatment and medication depends on the extent of the thyroid disorder.
Interesting Questions about Thyroid:
Graves’ disease is the most common form of hyperthyroidism. It affects many Americans, including Olympic athlete Gail Devers, who won a gold medal in track after being diagnosed with and treated for Graves’ disease.
Graves’ disease is caused by problems with the immune system. Normally, the immune system defends the body against germs and viruses. In autoimmune diseases such as Graves’, the immune system attacks the body’s own tissues. In Graves’ disease, the body produces antibodies which make the thyroid gland produce too much thyroid hormone.
Diseases of the immune system tend to run in families and are about five times more common in women. Graves’ is linked to other autoimmune conditions, such as Hashimoto’s thyroiditis, premature gray hair, diabetes mellitus, arthritis and patchy loss of skin pigment (vitiligo).
As with any disease, it is important that you watch for the early warning signs of hyperthyroidism. However, only your doctor can tell for sure whether or not you have the disease. Your doctor may examine:
- your history and physical appearance
- the amount of thyroid hormones, thyroid stimulating hormone (TSH), and thyroid stimulating antibodies in your blood
- the structure and function of your thyroid gland, using thyroid imaging, which takes a picture of the gland after you have been given a small amount of radioactive iodine
If you have thyroid disease, your doctor can discuss which treatment is right for you. The two basic goals for treating thyroid disease are to return thyroid hormone levels to normal and to remove potentially cancerous lumps. Treatments include radioactive iodine, antithyroid drugs, beta-blocking drugs, thyroid hormone pills, and surgery. There are several types of treatment:
- Radioactive iodine is used to shrink a thyroid gland that has become enlarged or is producing too much hormone. It may be used on patients with hyperthyroidism, a goiter, or some cases of cancer.
- Surgery is normally used to remove a cancer and may also be used to remove a large goiter.
- Thyroid hormone pills are a common treatment for hypothyroidism, for patients with a goiter, and for patients who have had thyroid surgery. The pills provide the body with the right amount of thyroid hormone.
- Anithyroid drugs and beta-blocking drugs are used to treat hyperthyroid patients.
