What Are Thyroid Blood Tests And Why Are They Taken

Thyroid blood tests are used to tell if your thyroid gland is functioning properly by measuring the amount of thyroid hormones in your blood. They are done by withdrawing blood from a vein in your arm. These blood tests help to diagnose thyroid diseases.

The thyroid is a butterfly-shaped gland located in the front part of your neck. Its job is to produce thyroid hormones, which travel through your bloodstream and regulate many aspects of your bodys metabolism, including temperature, weight, and energy.

Thyroid blood tests show if you have:

  • Hyperthyroidism: Overactive thyroid producing more thyroid hormones than your body needs. Hyperthyroidism speeds up your metabolism, which can cause weight loss, rapid heartbeat, insomnia, puffiness around the eyes, anxiety and other symptoms. The most common cause of hyperthyroidism is Graves disease.
  • Hypothyroidism: Underactive thyroid producing too few thyroid hormones. Hypothyroidism slows down your metabolism, which can cause weight gain, menstrual irregularity, dry and puffy skin, fatigue and other symptoms. The most common cause of hypothyroidism is Hashimotos disease.

Thyroid blood tests are used to diagnose thyroid disorders associated with hyper- or hypothyroidism. These include:

Blood Lymph And Nerve Supply

TSH or thyroid stimulating hormone test, TSH levels &  TSH ...

The thyroid is supplied with arterial blood from the superior thyroid artery, a branch of the external carotid artery, and the inferior thyroid artery, a branch of the thyrocervical trunk, and sometimes by an anatomical variant the thyroid ima artery, which has a variable origin. The superior thyroid artery splits into anterior and posterior branches supplying the thyroid, and the inferior thyroid artery splits into superior and inferior branches. The superior and inferior thyroid arteries join together behind the outer part of the thyroid lobes. The venous blood is drained via superior and middle thyroid veins, which drain to the internal jugular vein, and via the inferior thyroid veins. The inferior thyroid veins originate in a network of veins and drain into the left and right brachiocephalic veins. Both arteries and veins form a plexus between the two layers of the capsule of the thyroid gland.

What Is Thyroid Function Test

Thyroid function test is used to check how well your thyroid is working and to find the cause of problems such as hyperthyroidism or hypothyroidism. The thyroid is a small, butterfly-shaped gland in the front of your neck that makes two thyroid hormones: thyroxine and triiodothyronine . Thyroid hormones control how your body uses energy, so they affect nearly every organ in your body, even your heart.

Thyroxine and triiodothyronine circulate almost entirely bound to specific transport proteins, and there are some situations which these proteins could change their level in the blood, producing also changes in the thyroxine and triiodothyronine levels .

The thyroid function test usually includes:

The total T4 and total T3 tests have been used for many years, but they can be affected by the amount of protein available in the blood to bind to the hormone. The free T4 and free T3 tests are not affected by protein levels and are thought by many to be more accurate reflections of thyroid hormone function. In most cases, the free T4 test has replaced that of the total T4 test. However, some professional guidelines recommend the total T3 test, so either total T3 or free T3 test may be used to assess thyroid function.

Thyroid blood tests help health care professionals diagnose thyroid diseases such as:

Your doctor will start with blood tests and may also order imaging tests.

  • Increases, decreases, and changes in the proteins that bind T4 and T3
  • Pregnancy

Drawing Blood For Thyroid Function Tests

Talk to your doctor about any medications youre taking, and tell your doctor if youre pregnant. Certain medications and being pregnant may influence your test results.

A blood draw, also known as venipuncture, is a procedure performed at a lab or a doctors office. When you arrive for the test, youll be asked to sit in a comfortable chair or lie down on a cot or gurney. If youre wearing long sleeves, youll be asked to roll up one sleeve or to remove your arm from the sleeve.

A technician or nurse will tie a band of rubber tightly around your upper arm to make the veins swell with blood. Once the technician has found an appropriate vein, theyll insert a needle under the skin and into the vein. You may feel a sharp prick when the needle punctures your skin. The technician will collect your blood in test tubes and send it to a laboratory for analysis.

When the technician has gathered the amount of blood needed for the tests, theyll withdraw the needle and place pressure on the puncture wound until the bleeding stops. The technician will then place a small bandage over the wound.

You should be able to return to your normal daily activities immediately.

Are Test Results Accurate

Although no test is 100% correct all the time, your TSH test is likely to reflect your level of thyroid-stimulating hormone accurately. Most labs now use a highly precise, third-generation testing process for TSH. This method of testing is accurate to within 0.01 mIU/L. Some labs use an older, second-generation testing method, which is accurate to within 0.1 mIU/L.

It is important to bear in mind that thyroid tests are a snapshot of what is going on in your body at the moment the test sample is taken. Your TSH levels may fluctuate based on factors discussed above, such as pregnancy, illness, and age.

What Is The Function Of The Thyroid Gland

Hashimoto’s Causes Suffering and Low Thyroid Symptoms Even If TSH Blood Test Is “Normal”

The thyroid gland is part of the endocrine system of the body. Organs of the endocrine system secrete hormones. The primary function of your thyroid gland is to secrete thyroid hormones. The thyroid hormones are involved in regulating many of your bodily functions, such as your breathing, heart rate, temperature, how quickly you burn calories, and digestion, among other functions. Babies and children need adequate amounts of thyroid hormones for brain development and growth. Your thyroid needs iodine in order to manufacture these thyroid hormones. Foods that are naturally rich in iodine include seafood and plants grown in iodine-rich soil. Iodised salt is another good source of dietary iodine.

When Abnormal Thyroid Function Tests Are Not Due To Thyroid Disease

While blood tests to measure thyroid hormones and thyroid stimulating hormone are widely available, it is important to remember that no all tests are useful in all circumstances and many factors including medications, supplements, and non-thyroid medical conditions can affect thyroid test results. An endocrinologist can help you make sense of thyroid test results when there is a discrepancy between your results and how you feel. A good first step is often to repeat the test and ensure there are no medications that might interfere with the test results. Below are some common reasons for mismatch between thyroid tests and thyroid disease.

Non-thyroidal illness Significant illness, such as an infection, cancer, heart failure, or kidney disease, or recent recovery from an illness can cause changes transient changes in the TSH. Fasting or starvation can also cause a low TSH. An endocrinologist can help to interpret changes in thyroid function tests in these circumstances to distinguish non-thyroid illness from true thyroid dysfunction.

Test interference Biotin, a common supplement for hair and nail growth, interferes with many thyroid function tests and can lead to inaccurate results. Endocrinologists recommend stopping biotin supplements for 3 days before having a blood test for thyroid function.

In People Being Treated For Thyroid Disease

A high TSH may be found in people being treated for either hypo- or hyperthyroidism.

With hypothyroidism, a high TSH usually means that the dose of thyroid hormone replacement needs to be increased.

In some cases, however, the dose is OK, but the medication is not being fully absorbed. For example, many foods and medications can affect the absorption of Synthroid in your system. Learning what to avoid while taking this medication is important for it to work properly.

With hyperthyroidism, a high TSH usually means that the treatmentbe it surgery, radioactive iodine, or medicationswas so effective in limiting the production of thyroid hormone it caused the person to become hypothyroid.

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.

How The Immune System Responds To Food

There are a couple of ways the immune system responds to foodmainly, food allergies and food sensitivities.

Youre probably pretty aware of the effects of food allergies. Jane eats shellfish. Janes face blows up like a balloon and goes to the ER.

Breathing difficulties, hives, and swelling are common. These IgE reactions are immediate and involve a particular part of the immune system in their reaction.

However, there are other branches of the immune system that also cause different, delayed food reactions. Known as food sensitivities, these can occur up to 3 days after eating a problematic food.

Food sensitivities can include symptoms such as:

  • Headaches and migraines
  • Irritability, anxiety and depression
  • GI symptoms such as gas and bloating

While food sensitivities can vary from person to person, there are some foods that are known to have a big effect on the GI tract in everyone.

Lets take a closer look at the effects of these foods to avoid for Hashimotos and autoimmunity.

What Happens If Hypothyroidism Is Not Treated

Hypothyroidism can become a serious and life-threatening medical condition if you do not get treatment from a healthcare provider. If you are not treated, your symptoms can become more severe and can include:

  • Developing mental health problems.
  • Developing a goiter .

You can also develop a serious medical condition called myxedema coma. This can happen when hypothyroidism isnt treated.

Iodine is most essential to maintain a healthy thyroid. Iodine is the critical ingredient for the production of thyroid hormones. We dont need a lot of iodine, it is said that one teaspoon of iodine is enough for a lifetime. Nonetheless, the daily and constant supply of this micronutrient is important. Too much iodine at once is counter-productive and causes your thyroid to produce less hormones. The best way to get your daily dose of iodine is through eating healthy foods like seafood and dairy products. In addition, iodized salt is a good source and you can use it to season your food. Nowadays, iodine is added to salt to combat goitres .

What Are The Types Of Thyroid Disorders

    Blood tests are used to diagnose hypothyroidism or hyperthyroidism. They do not point to a specific cause. In order to determine a cause of the thyroid abnormality, the doctor will consider the patient’s history, physical examination, and medical condition. Further testing might be used to isolate an underlying cause. These tests might include more blood testing for

    • thyroid antibodies,
    • ultrasound of the thyroid gland, or
    • others.

    If thyroid cancer is suspected and surgery may be required, your physician may ask for a blood test known as thyroglobulin.

    • Thyroglobulin is a protein made only by thyroid cells.
    • If the thyroglobulin level at baseline is detectable or elevated it can be used as a tumor marker.
    • After a total thyroidectomy for cancer the level should fall to an undetectable range since the cells that make thyroglobulin have been removed.
    • If the level remains detectable after surgery, there is a possibility of thyroid tissue elsewhere in the body, and metastatic disease should be considered.
    • If the level is undetectable for a period of time after surgery and then starts to climb, a recurrence of the cancer – either at the primary site or elsewhere in the body should be considered.

    Molecular Markers In Fine

    Although still early in clinical application, the use of genetic biomarkers to assist in interpretation of FNAB samples is likely to greatly enhance the ability to distinguish benign from malignant thyroid nodules in conjunction with cytology. The current algorithms for the extent of thyroid surgery based upon these results are evolving. This stands in distinct contrast to immunohistochemical staining techniques such as HBME-1, galectin-3, cytokeratin, which may assist with indeterminate FNAB specimens, but truthfully have not dramatically changed clinical practice due to difficulties with the amount of tissue needed and subjective interpretation of stains .
