If you have been diagnosed with hypothyroidism, you will likely be given a home Thyroid Test as part of your initial treatment. Your doctor will probably explain that the blood tests are necessary to assess the thyroid function and to determine the best course of treatment. The most commonly prescribed treatment for hypothyroidism is Levothyroxine. This drug contains synthetic T4 or a thyroid hormone which your body needs to maintain normal function. Levothyroxine and other synthetic hormones are usually only prescribed to people in their late twenties or early thirties.
To determine whether you are truly experiencing hypothyroidism, your doctor will test your blood for high levels of TSH or thyroid stimulating hormone. High levels of this hormone will indicate an underactive thyroid which is known as Hashimoto's thyroiditis. If you test positive for this condition your doctor will likely want to start you on an appropriate thyroid hormone replacement treatment. Under normal circumstances your body produces sufficient amounts of thyroid hormone to supply your needs but inadequate amounts cause problems.
A home Thyroid Test can be used to measure your thyroid function as well as to find out if you are suffering from Hashimoto's disease or other thyroid problems. Your health insurance may cover part or all of the cost of a thyroid test kit. Most health insurance plans cover diagnostic tests such as blood tests, fasting plasma samples and urine tests. Some health insurance plans require urine testing as well as a physical exam and some may only require a hair testing or skin testing for diagnosis.
Home thyroid tests can also be used to determine if you are experiencing any symptoms of chronic thyroid problems such as goiter or slowed metabolism. These symptoms can indicate an underlying issue which needs to be addressed. Thyroid hormones are essential to proper thyroid function. They help regulate growth, metabolism and fluid balance in the body. If your thyroid hormones are not functioning properly or you are experiencing symptoms it is important to consult with your doctor for an evaluation.
An underactive thyroid-stimulating hormone is one of the many causes of hypothyroidism. An overactive thyroid-stimulating hormone is one of the causes of hyperthyroidism. A blood test measures the level of the thyroid-stimulating hormone, known as TSH. High levels of TSH can be caused by various medical conditions such as tumors, infection, liver disease, hormonal imbalances or excessive iodine in the blood stream.
An endocrine disorder such as Cushing's syndrome can cause increased levels of the hormone thyroxine to be produced and interfere with the functioning of the pituitary gland. Anemia and thyroid diseases are some of the autoimmune disorders that can affect the function of the pituitary gland. Blood tests can detect these ailments by measuring the antibodies which attack the thyroid.
A lab evaluation does not give definitive information about whether a person has these ailments or not. It will only state whether you are experiencing symptoms and the lab test only tells the level of activity of the thyroid. It can be really helpful if you can have a few laboratory tests done, but you should always remember that a home test is not able to determine whether you really have these problems or not. A doctor should be able to tell you with certainty whether you have these conditions or not. When in doubt, you should immediately report to your doctor for proper diagnosis and treatment.
Free T4 and homogonin are the substances released by the pituitary gland. A low level of these substances is associated with an under active thyroid. As we age, production of free T4 and homogonin decreases because the body cannot produce them as effectively as it use to when we were younger. The body cannot produce these substances, so it is essential to get them back into action. This is why a home test is really useful.
