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.

How Do I Prepare For A Thyroid

The TSH test doesnt require any special preparation. However, its important to tell your doctor if youre taking medications that might interfere with the accuracy of the TSH measurement. Some medications that could interfere with a TSH test are:

  • amiodarone
  • potassium iodide
  • biotin

You may need to avoid using these drugs before the test. However, dont stop taking your medications unless your doctor tells you to do so.

A TSH test involves taking a sample of blood. The blood is typically drawn from a vein thats inside the inner elbow.

A healthcare provider will perform the following procedure:

  • First, theyll clean the area with an antiseptic or other sterilizing solution.
  • Theyll then tie an elastic band around your arm to make the veins swell with blood.
  • Once they find a vein, theyll insert a needle into the vein to draw blood. The blood will be collected in a small tube or vial attached to the needle.
  • After they draw enough blood, theyll remove the needle and cover the puncture site with a bandage to stop any bleeding.
  • The entire procedure should only take a few minutes to complete. The blood sample will be sent to a lab for analysis.

    Once your doctor receives the test results, theyll schedule an appointment with you to discuss the results and explain what they may mean.

    What Is A Thyroid

    A thyroid-stimulating hormone test measures the amount of TSH in the blood. TSH is produced by the pituitary gland, which is located at the base of your brain. Its responsible for regulating the amount of hormones released by the thyroid.

    The thyroid is small, butterfly-shaped gland located in the front of the neck. Its an important gland that creates three primary hormones:

    • triiodothyronine
    • thyroxine
    • calcitonin

    The thyroid controls numerous different bodily functions, including metabolism and growth, through the release of these three hormones.

    Your thyroid will produce more hormones if your pituitary gland produces more TSH. In this way, the two glands work together to make sure the right amount of thyroid hormones is produced.

    However, when this system is disrupted, your thyroid can produce either too many or too few hormones.

    A TSH test is often performed to determine the underlying cause of abnormal thyroid hormone levels. Its also used to screen for an underactive or overactive thyroid gland. By measuring the level of TSH in the blood, your doctor can determine how well the thyroid is working.

    Your doctor may order a TSH test if youre experiencing symptoms of a thyroid disorder. Thyroid diseases can be categorized as either hypothyroidism or hyperthyroidism.

    Thyroid Conditions Can Be Difficult To Diagnose

    While a simple blood test can easily determine how much thyroid hormone you have in your blood, doctors often don’t think to check TSH or other thyroid levels since the symptoms of a thyroid problem can mimic the symptoms of many other conditions.

    Patients may have a variety of illnesses that can all cause fatigue and brittle hair, says Stuart M. Weiss, MD, an endocrinologist and assistant professor at New York University in New York City. But unless the physician gets the thyroid numbers to match the diagnosis, its difficult to blame the thyroid.

    What makes matters worse is that doctors dont always agree on how to read thyroid-related blood test results.

    Until the last six or seven years, doctors generally agreed that a TSH level of 0.5 to 5.0 was normal, and that anybody with those levels of TSH wouldnt be considered to have a malfunctioning thyroid.

    But some endocrinologists worried that this broad interpretation of results meant that people with thyroid disorders were going undiagnosed and untreated. This includes a subset of thyroid patients who are said to have subclinical thyroid disorder, which generally means they appear to have no, or few, symptoms of hypothyroidism. Their T3 and T4 levels are normal, but their TSH levels are higher than normal.

    The Thyroid Screening Test

    The thyroid stimulating hormone, or TSH test, is used as a screening test for thyroid disease, as well as a test for monitoring the correct dose of medication needed for an individual.

    TSH is a pituitary hormone that responds to low/high amounts of circulating thyroid hormone. If youre new to thyroid lab testing, it may seem counterintuitive, but an elevated TSH means that you do not have enough thyroid hormone on board and that you are hypothyroid. This is because the TSH hormone senses low thyroid levels and is released when there is a lack of it, in an effort to get the body to make more.

    In advanced cases of Hashimotos and primary hypothyroidism, this lab test will be elevated. In the case of Graves disease and hyperthyroidism, TSH levels will be low. People with Hashimotos and mild or central hypothyroidism, may have a normal reading on this test.

    If youve been a thyroid patient for a while, youre probably thinking to yourself, Well, of course, doesnt everyone know that? and I have to warn you Ive unfortunately seen physicians who have mistakenly thought that a low TSH meant one had an underactive thyroid, and a high TSH, an overactive thyroid putting their patients in really dangerous situations by over or under medicating them!

    Thus, many physicians may miss the patients who are showing an elevated TSH. This is one reason why patients should always ask their physicians for a copy of any lab results.

    Understanding Thyroid Stimulating Hormone

    As mentioned above, the thyroid stimulating hormone is produced by the pituitary gland. It works sort of like the master of the hormones, and rules the production of T3 and T4 from its control center.If you have too much TSH, it might mean that your thyroid gland isnt making enough T3 or T4. Remember, the TSH is supposed to stimulate the thyroid gland but if the gland isnt responding, then youll have too much TSH in your system.If your TSH levels are too low, it may mean that your thyroid gland is making too much thyroid hormone. This excessive thyroid production could actually suppress the TSH.

    A word of warning for pregnant women: Its incredibly important that your hormones are balanced in pregnancy, as thyroid stimulating hormone plays a role in the development of a healthy fetus.

    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.

    Understanding Thyroid Labs For Medication Prescriptions And Adjustments

    Thyroid labs, especially TSH, free T3, and free T4, are going to be critical for determining if you need to start, increase, or reduce the dose of your thyroid hormone medications, as well as if youre on the right thyroid medications.

    Some physicians who prescribe thyroid medications will not prescribe a medication unless the TSH is above 10 IU/mL, and will be satisfied when a person who is taking thyroid meds has a TSH under 10 IU/mL. I think this is the reason why many people continue to have fatigue, cold intolerance, difficulty with weight loss, and hair loss despite taking thyroid medications.

    When the TSH is between 2.5 IU/mL and 10 IU/mL, and/or when T3 and T4 are within normal limits, this is known as subclinical hypothyroidism. This means that the thyroid is still able to make enough thyroid hormone, but not without sacrifice. At this point, our thyroid is working overtime, leading to many of the common symptoms of hypothyroidism.

    The thyroid is constantly getting a signal to make more and more hormone, and your body is likely running out of nutrients to make more hormone. This results in additional inflammation to the thyroid, attracting more antibodies and fueling the autoimmune process. As many as 5 percent of people with subclinical hypothyroidism will progress to overt hypothyroidism each year due to this.

    What Is A Normal Thyroid Level

    Tests often used to assess thyroid hormone status include TSH and FT4 tests. The normal value for a laboratory test is determined by measuring the hormone in a large population of healthy individuals and finding the normal reference range. Normal ranges for thyroid tests may vary slightly among different laboratories, and typical ranges for common tests are given below.

    TSH normal values are 0.5 to 5.0 mIU/L. Pregnancy, a history of thyroid cancer, history of pituitary gland disease, and older age are some situations when TSH is optimally maintained in different range as guided by an endocrinologist.

    FT4 normal values are 0.7 to 1.9ng/dL. Individuals taking medications that modify thyroid hormone metabolism and those with a history of thyroid cancer or pituitary disease may be optimally managed with a different normal FT4 range.

    Total T4 and Total T3 levels measure bound and free thyroid hormone in the blood. These levels are influenced by many factors that affect protein levels in the body, including medications, sex hormones, and liver disease. A normal Total T4 level in adults ranges from 5.0 to 12.0g/dL. A normal Total T3 level in adults ranges from 80-220 ng/dL.

    Free T3 assays are often unreliable and not routinely used to assess thyroid function.

    What Are Thyroid Blood Tests And Why Are They Taken

    Thyroid blood test results

    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:

    How To Understand The Results Of A Thyroid Scan

    Before undergoing a thyroid scan, the patient will have to undergo a blood test that will help in determining the patients thyroid levels. It is important to consult a healthcare physician when it comes to interpreting the results. The scan will provide a better understanding of the thyroid gland and its functioning. With the help of the scan, the doctor will be able to determine the shape, outline, and position of the thyroid. Through this, the doctor will be able to interpret if the gland is functioning as it should. Another important aspect the scan will uncover is the thyroid glands activeness.

    Screening Test For Thyroid Dysfunction

    Routine screening for thyroid dysfunction by measuring TSH levels is currently not recommended by the US Preventative Task Force.

    What are the current recommendations for screening for thyroid disease?

    The US Preventative Task Force, which recommends various screening tests in the United States, does not recommend routine screening for thyroid function. It no doubt agrees that screening does detect cases that do not show any symptoms i.e. cases of subclinical thyroid dysfunction. However, treating these cases has not resulted in much benefit. Mild changes in TSH alone sometimes recover on their own without treatment. False positive results during screening could also result in overtreatment. Taking into consideration the side effects of thyroid and anti-thyroid medications, this could prove more harmful than beneficial.

    According to the recommendations from the American College of Gynecology, routine thyroid testing is not recommended in all pregnant women and should be done only in women with symptoms of thyroid disease, history of thyroid disease in the past, or the presence of any other medical conditions associated with it, such as diabetes.

    What are the tests recommended for screening for thyroid disease?

    Taking a medical history and examining the patient can also help to diagnose thyroid disease, though changes in TSH usually occur before the development of physical changes.

    For screening congenital hypothyroidism, two methods are used:

    What Is Thyroid Stimulating Hormone

    ichroma⢠T3 & T4 procedure

    Thyroid-stimulating hormone is a hormone that stimulates the thyroid gland to produce thyroid hormones. The pituitary gland secretes more TSH when blood levels of T4 and T3 fall below normal, and reduces the TSH secretion when T4 and T3 levels rise. The hypothalamus region of the brain regulates pituitary gland activity.

    Testing Your Thyroid Levels

    According to the American Thyroid Association, there isnt one test for every situation in fact, there are several kinds of thyroid tests. But if you are concerned about thyroid issues, or if your hormones are imbalanced, your doctor may provide an initial TSH level blood test. This is because the TSH level can serve as a tip-off to other, more specific issues.Whats a normal TSH level? Most lab companies have a wide reference as it relates to TSH levels , Dr. Rice says. So, if your results are somewhere between 0.4-4.0, youd be in the normal range. However, there is research that suggests that the reference range for TSH should be narrowed to 0.4 to 2.5, says Dr. Rice, which means that the normal range could be even smaller than some healthcare providers might think.Generally, healthy TSH levels are an indicator the whole system is working well, but thats an oversimplification at best. A normal T3 level might be somewhere between 100 to 200 nanograms per deciliter , while a normal T4 level falls between 5.0 to 12.0 micrograms per deciliter . Free T4, which tests for the amount of T4 that is available in the body, should range between 0.8 to 1.8 nanograms per deciliter .
