How Much Is A Thyroid Blood Test

What Other Tests May Be Ordered In Addition To A Thyroid Panel

Which Thyroid Blood Tests Should You Do?

Blood tests that may be performed in addition to a thyroid panel may include:

  • Thyroid antibodies – to help diagnose autoimmune thyroid disease and distinguish it from other thyroid conditions
  • Calcitonin – to help diagnose C-cell hyperplasia and medullary thyroid cancer
  • Thyroglobulin – primarily to monitor treatment and recurrence of thyroid cancer
  • Thyroxine-binding globulin – to evaluate patients with abnormal T4 and T3 levels

What Is A Normal Range For A Thyroid Test

Laboratories use reference ranges when analysing the function of the thyroid. Typical reference ranges for a healthy individual may look like this:

  • TSH 0.27 4.2 mIU/L
  • FT4 12.0 22.0 pmol/L
  • FT3 3.1 6.8 pmol/L

Different laboratories use different reference ranges, but if your results fall outside of these parameters you could be diagnosed with hypothyroidism or hyperthyroidism.

Subclinical hypothyroidism, on the other hand, occurs when your blood TSH level is slightly raised but your FT4 is within the normal range.

How And When To Take Levothyroxine

Take levothyroxine once a day in the morning, ideally at least 30 minutes before having breakfast or a drink containing caffeine, like tea or coffee.

Food and caffeinated drinks can both stop your body taking in levothyroxine properly so it does not work as well.

If you stop taking levothyroxine your symptoms are likely to come back.

What Does A Full Thyroid Panel Include

Thyroid stimulating hormone

âThe pituitary gland produces thyroid-stimulating hormone in the brain. The primary job of TSH is to regulate the amount of thyroid hormonesâthyroxine and triiodothyronine âproduced by the thyroid gland. This blood test measures how much overall thyroid-stimulating hormone is in your blood. While this is the standard test most doctors authorize, it won’t provide detailed information on your thyroid activity. For instance, it may not show problems like your body not being able to use the available thyroid hormone.

Free T4

The thyroid produces two hormones: thyroxine and triiodothyronine . T4 is primarily inactive. Its primary job as a “storage hormone” is to transport T3 to the proper organs in your body. T4 must be converted to T3 before your body can use it to get energy or deliver oxygen to cells. The T4 test helps determine the level of thyroid hormone in the body however, it doesn’t provide enough information by itself because it can be affected by the amount of protein in your blood.

How To Prepare For A Thyroid Blood Test

How To Order Your Own Thyroid Blood Tests

Have you been advised a thyroid blood test? This article will help you understand why you need the test and how to prepare for a thyroid blood test.

Thyroid disorders are becoming increasingly prevalent and have become a common illness worldwide. According to recent statistics, an estimate of 42 million people in India suffers from thyroid disorders. It comes under the umbrella of the term lifestyle disorders.

In India, such high number of thyroid cases can be because of lack of proper nutrition and unavailability of therapeutic sources. Lack of awareness and education and inadequate screening for thyroid disorders are other major contributing factors.

Thyroid Gland is A Butterfly-shaped Gland Located in The Neck Which Synthesizes and Releases Following The Hormones

  • T3 Tri Iodothyronine
  • T4 Thyroxine
  • Calcitonin
  • Thyroid Stimulating Hormone is secreted by the pituitary gland which stimulates the thyroid gland to produce T3 and T4. In blood, 80% of T3 and 70% of T4 hormones are bound to a transport protein, thyroxine binding globulin .

    About 0.05% T4 and 0.2% T3 are found in free or unbound form in the plasma. The thyroid gland is one of the most important endocrine glands of the body. It influences a lot of body functions by secreting the thyroid hormones.

    It is Responsible for Regulating and Maintaining The Following Bodily Functions

  • Basal Metabolic Rate
  • Blood Pressure and Normal Cardiac Output
  • Heat Production in The Body
  • Renal Function and Glomerular Filtration Rate

    In People With Thyroid Disease

    In people being treated for hypothyroidism, a low TSH level may mean:

    • Overmedication with thyroid hormone replacement
    • Interactions that cause increased absorption or activity despite an optimal dose of medication
    • Central hypothyroidism

    In people being treated for hyperthyroidism, a low TSH level usually means that further treatment is needed to reduce thyroid hormone levels.

    It could also mean that a person must continue to be monitored to make sure thyroid hormone levels return to normal. This is often the case for people who have temporary thyroiditis related to pregnancy or chemotherapy treatment.

    • Treatment may be more aggressive than needed

    • Medication may be absorbing too much

    What Is Thyroxine

    Thyroxine is a hormone produced by the thyroid gland its also known as T4. Once it is released from the thyroid, it travels in the bloodstream to the various organs of the body and is converted to a more active form, triiodothyronine .

    Thyroxine is important for the function of the heart and digestive system, metabolism, bone health and brain development.

    How To Get Tested

    A thyroid panel requires a blood sample. Laboratory testing involves using a needle to remove a small amount of blood from a vein in your arm. The procedure can happen in the doctors office, hospital, or another laboratory.

    In most cases, a thyroid panel is ordered by a doctor. Sometimes the thyroid panel analysis is automatically done by the lab on the original blood sample if an initial evaluation finds abnormal levels of thyroid-stimulating hormone.

    What Should I Do To Prepare For A Thyroid Function Test

    Thyroid blood spot tests

    Thyroid function tests usually require very little preparation.

    You don’t need to fast before the blood test. And it doesn’t matter if you have taken your thyroid medicine just before the blood test.

    Tell your doctor if you are taking any medication, as some medicines can alter the test results and how they are interpreted.

    It is also important to mention if you have had any X-ray tests that have used a special contrast dye, as this may contain iodine which can affect the results. Levels of thyroid chemicals also change in pregnancy, so tell your doctor if you are pregnant when the test is taken.

    Note: all newborn children have their thyroid function tested as part of the heel prick test which is offered to all babies and undertaken when they are 5 days old. See the separate leaflet called Newborn Baby Screening Tests for more information.

    Thyroid changes can happen during pregnancy. These changes are usually not significant, but some women can develop thyroid disease during pregnancy. Hyperthyroidism occurs in about one in every 500 pregnancies, while hypothyroidism occurs in approximately one in every 250 pregnancies. Hyperthyroidism, and less often, hypothyroidism, may remain after pregnancy. If you develop a thyroid condition during pregnancy, your health care provider will monitor your condition after your baby is born. If you have a history of thyroid disease, be sure to talk with your health care provider if you are pregnant or are thinking of becoming pregnant.

    What Is The Best Way To Take Thyroid Hormone

    The maintenance of steady and predictable thyroid hormone levels in the blood is essential to health . Patients with hypothyroidism need to take thyroid hormone by mouth as a medication each day. Dietary habits can influence how the body absorbs thyroid hormone.

    Thyroid medication should be taken on an empty stomach, around the same time each day. Afterwards, we recommend avoiding eating or drinking for 30-60 minutes. Most of our patients take thyroid hormone in the morning upon waking. Breakfast, including any coffee or milk, can be eaten 30-60 minutes later. The second most popular method is to take thyroid hormone in the evening, at least 3-4 hours after any food intake. You should try to establish a routine that allows you to be consistent each day.

    Certain medications and supplements decrease absorption of thyroid hormone and should be taken 3-4 hours after taking thyroid hormone. These include fiber supplements, calcium and iron supplements, proton pump inhibitors , soy products, and multivitamins with minerals.

    What Is Being Tested

    A thyroid panel is a group of tests that may be ordered together to help evaluate thyroid gland function and to help diagnose thyroid disorders. The tests included in a thyroid panel measure the level of thyroid hormones in the blood.

    A thyroid panel usually includes tests for:

  • Free T3 or total T3
  • Although rarely used these days, sometimes a T3 resin uptake test is included. T3RU and T4 can be used to calculate a free thyroxine index . This is another method for evaluating thyroid function. It corrects for changes in certain proteins that can affect total T4 levels.

    The thyroid is a small butterfly-shaped organ that lies flat across the windpipe at the base of the neck that produces thyroid hormones, primarily T4 and some T3. These hormones travel throughout the body and regulate the metabolism by telling the cells in the body how fast to use energy and produce proteins. Most of the hormone produced by the thyroid is T4. This hormone is relatively inactive, but it is converted into the much more active T3 in the liver and other tissues.

    Almost all of the T3 and T4 circulating in the blood is bound to protein. The small portions that are not bound are called “free” and are the biologically active forms of the hormones. Lab tests can measure the amount of free T3 or free T4 or the total T3 or total T4 in the blood.

    The body has an elaborate feedback system to control the amount of T4 and T3 in the blood.

    How Is The Sample Collected For Testing

    The Best Thyroid Test to Accurately Treat & Diagnose your Thyroid

    A blood sample is taken by a needle placed in a vein in your arm. A tourniquet is wrapped around your upper arm. It may feel tight. You may feel nothing at all from the needle, or you may feel a quick sting or pinch. The blood sample is collected in a tube, which is sent to the laboratory for analysis.

    • TSH This is a pituitary hormone that responds to low/high amounts of circulating thyroid hormone. In advanced cases of Hashimotos and primary hypothyroidism, this lab test will be elevated. In the case of Graves disease the TSH will be low. People with Hashimotos and central hypothyroidism may have a normal reading on this test.
    • Free T3 & Free T4-These tests measure the levels of active thyroid hormone circulating in the body. When these levels are low, but your TSH tests in the normal range, this may lead your physician to suspect a rare type of hypothyroidism, known as central hypothyroidism.

    What Is Free Thyroxine Concentration

    Free thyroxine concentration is the portion of the thyroxine hormone that is not bound to any blood proteins. Determination of fT4 involves a single blood sample that is sent to a referral laboratory for a special test called free T4 by equilibrium dialysis .

    “The concentration of fT4 is less affected by factors such as coexisting illness or medications.”

    The concentration of fT4 is less affected by factors such as coexisting illness or medications. However, a small proportion of normal cats are known to have fT4 concentrations above the reference range. Therefore, determination of fT4 is usually reserved for those cats with strong clinical signs of hyperthyroidism, whose initial screening tests supported hyperthyroidism, but whose total thyroxine concentrations were not high enough to be diagnostic.
