Reasons For Thyroid Disease Symptoms With Normal Thyroid Test Results

What Is a Normal Thyroid Level for a Dog?

Inside:;Research-Backed reasons why people have a thyroid function test normal values but still have thyroid disease symptoms. Whats the underlying reason for thyroid symptoms. What can affect false thyroid test results?

Thyroid problems are very prevalent these days, especially in middle-aged women.;Their prevalence is increasing day by day and many women suffer from terrible thyroid symptoms on a daily basis.

Hypothyroidism/Hashimotos disease come with a range of symptoms and oftentimes these symptoms can have multiple underlying reasons.;

There is a large number of women that we are seeing who have all thyroid disease symptoms with normal thyroid test results.;

So I get this question very commonly: Can my thyroid tests be false? ;or Can my thyroid test results be normal and I can still have hypothyroidism?

The Answer to these questions is not simple and a little complicated.

So to answer this question first we need to understand some basics about thyroid hormone production in our body.;

How Does Each Thyroid Antibody Impact Your Body

The presence of each antibody impacts your thyroid gland in sightly different ways:

Anti-thyroid peroxidase antibodies

The presence of TPOAb is associated with Hashimotos disease.;

TPOAbs attack the healthy tissue of the thyroid gland and stop it from producing thyroid hormones. This is also know as having an underactive thyroid or hypothyroidism.;

Up to 95% of people with Hashimotos will have TPO antibodies in their blood, making them the most obvious sign that you might have or will develop Hashimotos.

Anti-thyroglobulin antibodies

Thyroglobulin antibodies are another type of antibody associated with thyroid disease.

Like TPO antibodies, TgAb are also found in people with Hashimotos disease, but to a lesser extent.;

Thyroid receptor antibodies

This group of antibodies target the Thyroid Stimulating Hormone receptors in the Thyroid gland. This can cause the gland to overproduce Thyroid hormones, resulting in an overactive Thyroid ; or hyperthyroidism.;

Hyperthyroidism can lead to Graves disease, and the TRAb are the root cause.;

What is a Normal TSH Level

The normal TSH thyroid level usually depends on the medical lab, clinic, or a consulting physician. Previously, the normal TSH levels ranged from between 0.5 to 5.5. ;Currently, the TSH reference scale has been revised to the new standard range and the specified normal TSH level ranges from between 0.3 to 3.3. However, the old reference scale has been still followed by some labs, thus leading to a difference in thyroid treatment. Moreover, the TSH levels generally fluctuate throughout the day especially in the early morning and evening; even though the TSH levels can be same at 6 a.m. and 6 p.m. It has been reported that the TSH reaches it peak level in the evening, continues to be the highest until midnight. In addition, the TSH level considerably drops down at noon and the recorded TSH difference throughout the day varies by 2 3 points.

Normal T3 Level

Normal T4 Level

Thyroxine hormone is generally circulated in the blood through proteins. The liver converts T4 to T3 hormone. Two types of tests are suggested to determine the T4 level in blood. The normal total T4 range that indicates normal thyroid function ranges from between 4.5 to 12.5. The normal Free T4 levels can range from between 0.7 to 2. If the thyroid levels are above or below this preferred normal range, then it is more likely to be either one of these conditions; hypothyroidism or hyperthyroidism.

Below is the recommended normal range of thyroid hormones:

Thyroid Hormone Resistance And Also Disorder Of Thyroid Hormone Transport Or Metabolism

Pin on Thyroid test

These are conditions that are rare and very difficult to diagnose properly.;In these conditions sometimes because of genetic variation your body might become resistant to thyroid hormone.;This is similar to what we see in Type II Diabetes where the body becomes resistant to the lin hormone.

The second condition is where there is a problem with either too high levels of thyroid binding protein or low levels of thyroid-binding protein.;The thyroid hormone in the bloodstream is present in the bound form.;Thyroid hormone is bound to thyroid binding protein, so if there is a significant difference in the levels of these thyroid-binding proteins it can interfere with optimal levels.;Some of this condition is attributable to high cortisol levels and also is estrogen levels .;;

What Is A T4 Test

T4 Tests A;Total T4;test measures the bound and free thyroxine hormone in the blood. A;Free T4;measures what is not bound and able to freely enter and affect the body tissues.

What does it mean if T4 levels are abnormal? Importantly, Total T4 levels are affected by medications and medical conditions that change thyroid hormone binding proteins. Estrogen, oral contraceptive pills, pregnancy, liver disease, and hepatitis C virus infection are common causes of increased thyroid hormone binding proteins and will result in a high Total T4. Testosterone or androgens and anabolic steroids are common causes of thyroid hormone binding proteins and will result in a low Total T4.

In some circumstances, like pregnancy, a person may have normal thyroid function but Total T4 levels outside of the normal reference range. Tests measuring free T4 either a free T4 or free T4 index may more accurately reflect how the thyroid gland is functioning in these circumstances. An endocrinologist can determine when thyroid disease is present in the context of abnormal thyroid binding proteins.

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 .

Different Types Of Autoimmune Thyroid Disease

Falk: What on earth is autoimmune thyroid disease?

Kirk: Autoimmune thyroid disease is a complex term. Its not really one disease. Its rather a term that refers to a number of different ways that the immune system could affect the thyroid gland.

Falk: Where is the thyroid?

Kirk: The thyroid is on the base of the neck in the midline, so if you were to take your fingers and press right at the bottom of the neck, you probably wouldnt feel it because most thyroid glands are difficult to feel. Its about 4 centimeters tall on either sideits the shape of a butterfly, we like to say. Thats where its located.

Falk: So that organwhat is the thyroid supposed to do in the first place?

Kirk: The thyroid does a lot of things. It produces thyroid hormones. These hormones affect essentially every cell in the body. A simple way to think about what thyroid hormone does, is it is a contributor to metabolism and activity so it may rev up the system, so to speak. If its produced in appropriate quantities it keeps many organs and systems in equilibrium.

Falk: So if your thyroid is overworking or hyperactive, how do you feel?

Kirk: If your thyroid is overactive or if youre producing too much thyroid hormone you may lose weight without meaning to, you may be very hot, you may be sweaty, anxious, or have tremors that you or others may notice. We often hear people say that they have rapid heartbeat or fluttering sensation which we refer to as palpitations.

What are the Best Thyroid Levels for You?

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 Is Thyroid Hormone

Thyroid hormone is made by the thyroid gland, a butterfly-shaped endocrine gland normally located in the lower front of the neck. Thyroid hormone is released into the blood where it is carried to all the tissues in the body. It helps the body use energy, stay warm and keeps the brain, heart, muscles, and other organs working as they should.

Thyroid hormone exists in two main forms: thyroxine and triiodothyronine . T4 is the primary form of thyroid hormone circulating in the blood . To exert its effects, T4 is converted to T3 by the removal of an iodine atom; this occurs mainly in the liver and in certain tissues where T3 acts, such as in the brain. T3 normally accounts for about 5% of thyroid hormone circulating in the blood.

Most thyroid hormone in the blood is bound by protein, while only a small fraction is “free” to enter tissues and have a biologic effect. Thyroid tests may measure total or free hormone levels.

Drugs That Affect Thyroid Function Tests

Several drugs and medications can interfere with thyroid hormone productions;and levels in the body.

So when we are ordering tests and even treating people with those medications we need to have a high index of suspicion for thyroid abnormality because of medications.

Typical medications associated with drugs that affect thyroid function tests are Amiodarone, Lithium, dopamine agonists, steroids, metformin.

So if you are taking any one of these medications that can explain some of your symptoms but the test results might not be showing thyroid abnormality.;

In People Without Known Thyroid Disease

A high TSH in people who are not undergoing thyroid disease treatment usually indicates the presence of primary hypothyroidism.

This is by far the most common form of hypothyroidism, and it occurs because the thyroid gland produces an inadequate amount of thyroid hormones. The pituitary gland senses these low levels and increases the production of TSH.

An elevated TSH may also occur with normal thyroid function due to the presence of antibodies, proteins made by the immune system.

The Take Hormone Message

Optimal TSH T3 & T4 levels

Ultimately, our understanding of TSH is continually evolving and expanding as researchers add to the growing body of information on the matter. For this reason, itâs essential to work with healthcare professionals who are committed to staying abreast of this research and are experts in their chosen field. The body of literature is brimming with examples in which a TSH that is too high or too low may become problematic, so I recommend working closely with a healthcare professional to ensure a TSH within not only the ânormalâ range, but within an optimal range for your personal health and circumstances.

How To Keep Hypothyroidism Under Control

Because youll need to take thyroid medication every day for the rest of your life, even after the right dose is found, your hormone levels will be monitored regularly to be sure that your treatment is working properly. Eventually, most people with hypothyroidism can just be seen yearly by their doctor, Doria-Medina says.

The American Thyroid Association recommends that you keep your TSH within a narrow range of 0.5 to 2.5 mU/L, but dont be alarmed if your test results vary a little. Some variation is normal because your pituitary gland sends out TSH in pulses, not a steady stream. Also, factors like the time of day youre tested can make a difference. TSH levels are likely to be higher at night and lower during the day. Some people, including those who are pregnant or those with a history of thyroid cancer, have different TSH goals. Talk to your doctor about the target TSH range thats right for you.

If you have new or worsening symptoms or your health status changes such as if you become pregnant, go through menopause, or are given another medicine that can interfere with the absorption of your thyroid hormones, such as anticonvulsants, certain antacids, or iron or calcium supplements you should see your doctor and have your blood tested again, even if its ahead of schedule.

Symptoms Of A Thyroid Issue

What are the symptoms of a thyroid problem? The symptoms of a thyroid problem comes from hyperthyroidism or hypothyroidism, both caused by unbalanced thyroid levels. Thyroid disease symptoms include:

  • Enlarged thyroid
  • Swelling
  • Eye problems

Graves disease or Hashimotos thyroiditis can lead to dangerously high or dangerously low thyroid hormone levels, respectively. There are many triggers for Graves or Hashimotos.

Its crucial to know if a patients thyroid imbalance is due to Hashimotos or Graves disease these are autoimmune conditions with a significantly different root cause and treatment strategy than thyroid disease which is not autoimmune in nature.

Thyroxine Triiodothyronine And Tsh Levels

Thyroid Test | Normal Thyroid Levels | Optimal Thyroid Levels | T3 vs T4

The main job of the thyroid gland is to make the hormone thyroxine, also known as T4 because it has four iodine molecules. The thyroid also makes the hormone triiodothyronine, known as T3 because it has three iodine molecules, but in smaller amounts, explains Cathy Doria-Medina, MD, an endocrinologist with HealthCare Partners Medical Group in Torrance, California. The thyroid gland makes mostly T4, the T4 has to be converted to T3, because T3 is the part of thyroxine that actually does the work, she says.

The pituitary gland at the base of the brain controls hormone production in your body. It makes thyroid-stimulating hormone , which tells the thyroid gland how much T4 and T3 to produce. The TSH level in your blood reveals how much T4 your pituitary gland is asking your thyroid gland to make. If your TSH levels are abnormally high, it could mean you have an underactive thyroid, or hypothyroidism. Thats because it indicates your pituitary gland is producing more TSH in an effort to stimulate your thyroid to produce thyroid hormone, according to the Mayo Clinic.

TSH levels go in the opposite direction of your thyroid hormone, Dr. Doria-Medina explains. If youre making too little thyroid hormone, your TSH will go up. If youre making too much thyroid hormone, your TSH will go down.

If your TSH is higher than 4.0 mU/L on repeat tests, you probably have hypothyroidism.

Whats A Healthy Thyroid Level

There is no one answer to this question, as normal thyroid levels vary by individual. However an indication of average healthy levels can be established by testing a significant number of individuals in order to establish a reference range.

Such testing suggests the following thyroid normal ranges for adults:

  • TSH: 0.5 to 5 mIU/L
  • T4: 5.0 to 12.0g/dL
  • T3: 80-220 ng/dL

High Thyroglobulin Levels Ways To Support The Thyroid

Improving your thyroglobulin levels wont necessarily cause improvement in thyroid function, but it can be used as a biomarker for your thyroid health.

The following is a list of complementary approaches to support the thyroid that may also balance high Tg levels. Though studies suggest various dietary and lifestyle factors may lower Tg levels, additional large-scale studies are needed.

Remember to talk to your doctor before making any major changes to your day-to-day routine.
