How To Test For Thyroid Problems At Home

How to check your thyroid hormones at home?

The Everlywell at-home thyroid test can tell you if your thyroid hormone levels suggest hypothyroidism. This thyroid function test requires only a few drops of blood as a sample. After getting your online test results, you can easily see your levels of thyroid-stimulating hormone , free T3 and T4, and TPO antibodies. High TSH levels and/or low T3 and T4 can indicate hypothyroidism.

You can also take our thyroid test at home to check your hormones for indications of hyperthyroidism. Hyperthyroidism means your thyroid gland is overactive: itâs producing too many hormones. Low levels of TSH and/or high T3 and T4 can suggest hyperthyroidism.

Treating Abnormal Tsh Levels

A doctor will diagnose a thyroid disorder by reviewing your medical history, conducting a physical examination, and doing multiple tests, including a blood test. In some, but not all, instances, you may need a thyroid ultrasound or thyroid scan.

Treatments for hypothyroidism and hyperthyroidism can change over time, based on the severity of the condition and your response to medication.

What Are Thyroid Hormones

The thyroid is a small gland that sits at the front of your neck. Itâs responsible for controlling many of the bodyâs key activities â such as metabolism. It does this by releasing specific hormones into the bloodstream.

A hormone is small chemical messenger that allows different parts of your body to âtalkâ with each other. The thyroid makes two kinds of hormones: thyroxine and triiodothyronine . These hormones circulate in your blood, allowing the thyroid gland to regulate many of the bodyâs important functions, such as:

  • Metabolism â Thyroid hormones tell the body when to burn fat, which gives you more energy. Thyroid hormones can also trigger the production of glucose â a sugar formed from carbohydrates â to provide your body with more energy.
  • Heart rate â Thyroid hormones can affect your resting heart rate .
  • Internal body temperature â Thyroid hormones are involved in regulating your bodyâs internal temperature â so the thyroid gland acts a bit like a thermostat that helps make sure your body doesnât get too cool or too hot.

Whatâs more, thyroid hormones can contribute to more wakefulness and alertness because of how they affect the nervous system.

In short, your body requires the right balance of thyroid hormone levels in order to effectively carry out many of its functions.

What Are Thyroid Hormone Blood Tests

The thyroid is a butterfly-shaped gland located near your Adam’s apple that produces the hormones triiodothyronine and thyroxine .4 T3 and T4 regulate all aspects of your metabolism, such as the rate at which your body uses carbohydrates, your body temperature, and your protein production.3

When your thyroid does not produce enough of these hormones , you may experience a lack of energy, weight gain, and depression. 2 Thyroid function blood tests–also known as thyroid hormone blood tests–can determine whether your thyroid is functioning correctly.7 A healthcare provider can administer these tests to help determine what’s causing your symptoms and which treatment may work best for you.

Signs You Should Do A Thyroid Function Test

Fasting And Thyroid Health: Check Your Hormones

There are three important hormones that are key to thyroid health: TSH, T3, and T4. These hormone levels can appear normal when checked, but they hold the key to potential thyroid conditions. All of these can be altered for the better through the art of fasting:

  • T4 doesnt convert to the active hormone T3. T4 hormone must be converted to T3 active hormone. If this conversion does not take place or is shunted into another direction , then the message to the cell will never get through. ONLY active T3 can be used in the cell.
  • Active T3 cant be used in the cell because its receptors on the cell are blunted. An important point that I teach is that hormone problems are not necessarily problems with hormones themselves, but rather the receptor to the hormone. This is similar to Type II Diabetes, where the diabetic has plenty of insulin but the receptors to the insulin are blunted and unable to hear the message in order to allow the glucose in the cell. Therefore, the glucose cannot get into the cell to produce energy. A similar situation occurs with the thyroid and T3.
  • All of these potential reasons for thyroid dysfunction can be helped through fasting.

    What Is The Thyroid

    Located on the lower part of the front of the neck, the thyroid is a butterfly-shaped gland that measures two inches in length. For men, the gland is located underneath the Adams apple, near the windpipe.

    The thyroid, which is part of the endocrine system, is responsible for the metabolism.

    When there are no issues with the thyroid, and its a normal size, it cannot be felt however, when it doesnt work right, it may become enlarged or could grow lumps of extra tissue.

    Abnormal Results Of A Thyroid Blood Test

    Since the most frequent concern, do you need to fast before a thyroid blood test has been addressed, let us move on to the three types of results of a thyroid blood test. Your thyroid blood test either shows a healthy result or an abnormal result . In the latter results, an abnormal result could be due to thyroid malfunction indicating either of the two hypothyroidism and hyperthyroidism

    A case where a high concentration of thyroid hormone is present in the blood is known as hyperthyroidism. Conditions that lead to this alleviation of blood thyroid hormone may include:

    • Excessive iodine
    • Thyroid Nodules

    On the other hand, a condition where a lower than normal concentration of thyroid concentration is present in the blood is called hypothyroidism. Conditions that can lead to a decreased value of thyroid hormone in blood include:

    • Iodine deficiency
    • Hashimotos thyroiditis

    Magnetic Resonance Imaging Scan

    MRI scans use magnets instead of radiation to create detailed cross-sectional images of your body. MRI can be used to look for cancer in the thyroid, or cancer that has spread to nearby or distant parts of the body. But ultrasound is usually the first choice for looking at the thyroid. MRI can provide very detailed images of soft tissues such as the thyroid gland. MRI scans are also very helpful in looking at the brain and spinal cord.

    Undetected Low Levels Of Thyroid Hormone May Underlie Subtle Changes That Can Increase Your Risk Of Cardiovascular Disease

    For a gland only two inches in size, the thyroid has a huge influence on our health. It produces a hormone that is carried in the bloodstream to all parts of the body. Thyroid hormone plays a major role in regulating metabolismthe process by which body cells convert nutrients into energyand thereby helps regulate body temperature, heart rate, and even brain function. So when thyroid hormone levels fall, the body slows.

    You’re probably aware of the common symptoms of low thyroid hormonefatigue, fuzzy-headedness, weight gain, cold hands, and dry skin. But if you’re like most of us, you’re likely to blame your diet and exercise regimen instead of your thyroid if your cholesterol levels and weight are creeping up, especially if you don’t have any of the other symptoms of low thyroid. “Symptoms are often nonspecific, and since women over 60 generally have more of these nonspecific symptoms, their doctors may not think to test for hypothyroidism,” says endocrinologist Dr. Jeffrey Garber, associate professor of medicine at Harvard Medical School and author of The Harvard Medical School Guide to Overcoming Thyroid Problems.

    Is Thyroid Curable Permanently

    Blood tests are all that’s needed to detect thyroid disease

    Yes, there is a permanent treatment for hyperthyroidism. Removing your thyroid through surgery or destroying your thyroid through medication will cure hyperthyroidism. However, once your thyroid is removed or destroyed, youll need to take thyroid hormone replacement medications for the rest of your life.

    What Causes Thyroid Disease

    Various reasons cause an imbalance of hormone production in your thyroid glands. A few of them can cause hypothyroidism, and others may cause hyperthyroidism.

  • Hypothyroidism: hypothyroidism is when the thyroid glands produce hormones below the normal range. This can be due to two reasons: primary or secondary. Hashimotos disease is an autoimmune disease known as chronic lymphocytic thyroiditis or Hashimotos thyroiditis. It is hereditary, which means either a family member had it, and it is passed down to you. Your immune system consequently attacks and then damages your thyroid, preventing the glands from producing enough substance. On the other hand, the secondary cause is not directly related to the thyroid however, any other disease may interrupt the process of thyroid glands producing enough hormones.
  • 2. Hyperthyroidism: it is when the thyroid glands produce hormones above the normal range. The leading cause of hyperthyroidism is Graves disease, where your glands lose control over the production of hormones. Another cause can be thyroiditis. It is inflammation in your thyroid glands that usually occurs after pregnancy in women. TSH having abnormal secretion and excessive taking of thyroid hormones are other reasons to cause hyperthyroidism.

    Thyroid Testing: How It Works

    Thyroid tests use a blood sample to measure various hormone levels. Thyroid-stimulating hormone , for example, is often measured to indirectly check if your thyroid gland is producing enough thyroid hormones. TSH levels are usually higher than normal in TSH test results if you have an underactive thyroid .

    Thyroid gland function tests can also measure thyroid hormones like thyroxine to provide a better understanding of how low â or how high â your thyroid hormone levels are.

    How Does A Blood Test For Hypothyroidism Work

    Pin on Thyroid health

    How to test for hypothyroidism?

    Itâs important to note that there is no hypothyroidism test that can check thyroid hormones andâbased only on those test resultsâconclusively determine if someone has hypothyroidism. Thatâs because both thyroid hormone testing and a physicianâs evaluation of symptoms and medical history is required for a diagnosis.

    A blood test for hypothyroidism is based on your levels of thyroid-stimulating hormone and the thyroid hormones T3 and T4. Because TSH signals the thyroid gland to produce more thyroid hormones, unusually high TSH levels can mean that your thyroid isnât making enough hormones.

    A thyroid lab test might also measure T3 and T4 to reveal just how low your thyroid hormone levels are, which can help your healthcare provider decide on a thyroid treatment strategy.

    Why Would I Need These Tests

    The thyroid gland‘s hormones help control some of your body’s metabolic processes, such as heart rate, blood pressure, body temperature and weight. Too much or too little of these hormones can make you ill.

    You might need thyroid tests if:

    • you have symptoms of hyperthyroidism or hypothyroidism
    • you are taking some form of thyroid hormone replacement treatment
    • you are female and being investigated for infertility

    Very rarely, babies are born without a working thyroid gland. For this reason, all Australian newborns are screened for hypothyroidism with a TSH test using a drop of blood taken from a heel prick.

    What Should Be Tested

    A full thyroid panel is required to obtain the most comprehensive and accurate look at how youre doing, as TSH alone and even TSH and Free T4 test without the other components of the thyroid panel, dont give the full picture.

    Free T3 and Thyroid Antibodies TpoAB and TgAB are important to monitor too. Many thyroid patients find that whilst their TSH is OK, their Free T3 and Free T4 are not optimal and so they still feel unwell. If your doctor wont order the full thyroid panel, do know that it is relatively inexpensive and simple to order these tests yourself. UK thyroid patients can order them from here and a worldwide link can be seen here.

    TSH serves as an average read out over the previous four to six weeks of your thyroid levels but doesnt give the most comprehensive view.

    Fasting And Thyroid Test Results

    Studies have shown that time of day and fasting can affect your results. If you test in the early morning after overnight fasting, the results may show higher levels. This is compared to tests done later in the day with no fasting.

    That can be a problem if you have subclinical hypothyroidism. This is when you have a mildly elevated TSH and normal free T4, but no symptoms. Free T4 is the active form of T4.

    This condition is diagnosed and monitored based solely on TSH. T4 and T3 levels are usually normal.

    If you get your blood test in the afternoon when you have not been fasting, your TSH levels will be lower. Because of this, your subclinical hypothyroidism may be missed.

    What Is A Thyroid Blood Test

    Hashimoto’s Blood Tests – 9 Tests EVERYONE Needs

    A thyroid blood test measures levels of a specific hormone in our body, known as the thyroid hormone or thyroid-stimulating hormone . For this reason, the thyroid blood test is also commonly referred to as a TSH test or a thyrotropin test. The thyroid is a small gland situated near your throat and produces hormones, which regulate a persons mood, the bodys usage of energy, body weight, body temperature, and muscle strength.

    Contrary to common belief, TSH is made by the pituitary gland in the brain, and not in the thyroid gland in the neck. Low thyroid levels in your body stimulate the release of TSH from the pituitary gland. Similarly, high levels of thyroid in your body will send signals to your pituitary gland to produce less TSH. levels of thyroid-stimulating hormone in the body deviating from the normal range indicates a thyroid dysfunction.
