What Is Thyroid Peroxidase Ab Test

What Can I Do To Change My Levels

Thyroid Peroxidase Antibody Test | Anti TPO Test

There are a number of nutrients that are important for your thyroid function:

  • Iodine needed to make thyroid hormones
  • Zinc needed to make thyroid hormones
  • Selenium needed to thyroid hormones
  • Iron plays an important role in thyroid hormone metabolism
  • Vitamin D plays an important role in your immune function and low levels are linked to autoimmune thyroid disorders

If your levels indicate you have a thyroid disorder, its important to work with your doctor to come up with a treatment plan.

How To Heal Your Thyroid

Based on the results of the TPOAbs test, the doctor will recommend certain treatment measures if necessary.

However, there are many things you can do on your own in order to prevent or lower the levels of antibodies. These measures can help delay progression or aid management of autoimmune thyroid conditions. Below, you can see some useful suggestions:

  • Modify your diet the first and most important thing you can do to lower levels of TPO antibodies is to modify your diet. Make sure to lower or avoid intake of heavily processed and refined foods, GMO foods, and foods laden with thickening agents, artificial sweeteners, thickening agents, food dyes, among others. Instead, try to include organic fruits and vegetables into your diet and other foods that are rich in nutrients and with amazing anti-inflammatory activity. You also need to consume fiber-rich foods which are beneficial for the digestive system i.e., your gut. Additionally, your diet also needs protein which assists in the repair of tissues in the body, participates in the transport of thyroid hormones throughout the body

Who Has Elevated Thyroid Antibodies

While high thyroid antibodies are one of the diagnostic criteria for Hashimotos disease surprisingly there are other health conditions associated with their presence. It means that there is a risk that eventually the person may develop Hashimotos and/or hypothyroidism later on.

1. Thyroid antibodies levels were found to be mild to moderately elevated in associated diseases such as systemic lupus erythematosus , thyroid cancer, thyrotoxicosis, rheumatoid arthritis, fibromyalgia, pernicious anemia, autoimmune collagen vascular disease and type 1 diabetes.

2. According to different studies, high thyroid antibodies were reported in a range of 1229% in patients with chronic hives . There is an increased prevalence of thyroid autoimmune disease such as positivity of thyroid antibodies, Hashimotos disease with or without hypothyroidism in people with chronic urticaria. However, there are no cases of Graves disease described among patients with chronic hives.

Test for thyroid antibodies and thyroid function are especially recommended for those patients who experience chronic hives that cannot be attributed to an allergen or any other obvious cause.These tests can rule out involvement of thyroid autoimmunity or help to confirm it as being the cause of this condition.

One study estimated that up to 12.5% of women can have elevated TPO thyroid antibodies during the first two trimesters of pregnancy and it can negatively affect development of the fetus and child.

What Does The Test Measure

Thyroid antibody testing detects and measures thyroid antibodies in the blood. Normally, antibodies attack foreign substances in the body, like bacteria, viruses, parasites and toxins.

In patients with autoimmune disorders, antibodies mistakenly target the bodys own tissues. These antibodies that attack the patients own body are also known as autoantibodies or antithyroid antibodies. Thyroid antibody testing may look for several types of thyroid antibodies:

  • Thyroid peroxidase antibodies : Thyroid peroxidase is an enzyme that is crucial to the production of thyroid hormones. TPOAb may interfere with the action of this enzyme. Almost all patients with Hashimotos thyroiditis have high levels of TPOAb.
  • Thyroglobulin antibodies : Thyroglobulin is a protein made by the thyroid gland. TgAb may be present when the thyroid has been damaged. Thyroglobulin antibodies are often measured in addition to thyroglobulin tests after a patient completes treatment for thyroid cancer.
  • Thyrotropin receptor antibodies : TRAb are antibodies that bind to the receptors on thyroid cells normally activated by thyroid-stimulating hormone . In Graves disease, an antibody called thyroid stimulating immunoglobulin binds to the TSH receptor and mimics the action of TSH. This causes constant stimulation of the thyroid gland, prompting it to release too much thyroid hormone into the bloodstream. Stimulation by TSI can also cause abnormal growth of the thyroid gland.

What Are Thyroid Peroxidase Antibodies

PPT

What I just described is what thyroid peroxidase does inside of the thyroid gland but this is completely different from thyroid peroxidase antibodies.

If you’ve been told that you have thyroid peroxidase antibodies, also referred to as TPO antibodies, then this information applies to you.

Your body creates antibodies to things that it wants to kill or get rid of.

In the healthy state, you should really never see antibodies to any part of your own body or tissues.

Why?

Because why would you want to get rid of something that is supposed to be in your body!

Antibodies are usually created to help your body eliminate infections or viruses but they can sometimes be created by your immune system to target your own body.

When this happens you are said to have an autoimmune disease .

We can break apart the word to understand exactly what it means:

Auto , immune , and disease .

In the case of thyroid peroxidase antibodies, your own body is creating antibodies that target, damage, and destroy, the thyroid peroxidase enzyme.

These antibodies are produced by the immune system and flow through your entire body until they find their target.

Once they reach their target their goal is to destroy it.

And because their target is located in the thyroid gland, your thyroid becomes the site of a war between your immune system and thyroid peroxidase.

As you might imagine, this results in damage to your thyroid gland which can become permanent if the damage is severe enough.

What Does It Mean When Thyroid Peroxidase Antibodies Are Low

Reference Range. The reference ranges for antithyroid antibodies are as follows: Thyroid peroxidase antibody : Less than 35 IU/mL. Thyroglobulin antibody : Less than 20 IU/mL. Thyroid-stimulating immunoglobulin antibody : Less than 140% of basal activity.

Likewise, can thyroid antibodies go away? All thyroid diseases can be treated, resulting in normal thyroid function. Occasionally, the thyroid stimulating antibodies do go away in patients treated with antithyroid drugs, resulting in remission of the Graves’ disease and allowing for discontinuation of the medications.

Also to know, what does it mean when thyroid peroxidase antibodies are high?

If your results show high levels of antibodies against thyroid peroxidase or thyroglobulin, you may have Hashimoto’s disease. The higher your level of antibodies, the more likely that you have a thyroid disease caused by your immune system.

How do you treat high thyroid antibodies?

Treatment is usually bed rest with beta blockers to control palpitations . Radioactive iodine, surgery, or antithyroid medication is never needed. A few patients have become permanently hypothyroid and needed to be placed on thyroid hormone.

Autoimmune Antibodies And Thyroid Disease

The thyroid is a gland located in the front of your neck. It produces important hormones that help control your metabolism and other body functions.

Your thyroid gets its instructions from the pituitary gland, a small structure in your brain. The pituitary gland releases thyroid stimulating hormone , which tells the thyroid gland to make thyroid hormone.

Antibodies are proteins your immune system makes to help protect you against infections. Sometimes antibodies can mistakenly attack your own tissues.

Some thyroid conditions happen because antibodies attack the gland and interfere with its normal hormone-making process. These conditions are called autoimmune diseases of the thyroid.

There are several types of thyroid antibodies. Each one attacks a different target in the thyroid hormone production process.

The most common thyroid antibodies are:

  • Anti-thyroperoxidase antibodies
  • Thyroid stimulating hormone receptor antibodies
  • Anti-thyroglobulin antibodies

Thyroid Antibody Test Results

Antibody levels can be tested with a blood sample. The antibody test measures the amount of antibody per milliliter or liter of blood in “international units.”

Normal values are:

  • TPO antibody: Less than 9 IU/mL
  • Thyroid-stimulating immunoglobulin antibody : Less than 1.75 IU/L
  • Anti-Tg antibody: Less than 4 IU/mL

Note that different laboratories may have different normal range values.

Thea Score: Assessing Your Risk For Hypothyroidism

What are TPO antibodies?

Once you have your lab results in hand, there is a great tool that your clinician can use to help determine the aggressiveness of your condition. The Thyroid Event Amsterdam Score is a score that can help assess your risk of progression into hypothyroidism.

The THEA score is used to help estimate the risk of developing hypothyroidism within five years in people who have TPO antibodies, and can also help estimate the risk for those who have relatives with thyroid diseases.

Please note that thyroid antibodies make a very big contribution to the total THEA score.

How does THEA work? It applies a certain amount of points towards different measures. These measures consist of genetic predisposition as well as lab test results. Ive included a chart that shows you how the scoring is made.

Genetic predisposition: We know there is a genetic component to developing Hashimotos, and it tends to run in families. So, if you have relatives with Hashimotos, that increases your risk. And if you have been diagnosed with thyroid disease, theres a greater chance that a loved one like your child, parent or sibling may be at risk as well.

Hashimotos can occur in two varieties: an organ wasting form associated with HLA-DR3 gene inheritance, and an enlarged thyroid form through HLA-DR5 inheritance.

People with these genes and who have a relative with Hashimotos would get points. Someone with multiple relatives with Hashimotos would get additional points.

Do Antibody Numbers Matter

Some clinicians will say that once you have thyroid antibodies, you will always have thyroid antibodies, so the actual number doesnt matter, as the antibodies can randomly fluctuate. I respectfully disagree. Antibodies fluctuate in response to triggers , and in my exhaustive experience, they can be an incredibly helpful marker for tracking disease progression. That said, they should not be the only marker. We also want to look at your overall health and the big picture are you feeling better or worse?

Risks And Side Effects

There are few risks or side effects associated with a blood test. Because veins vary in size, your healthcare provider may occasionally have difficulty obtaining the blood sample.

Any time your skin is broken, theres a slight risk of infection. You should notify your doctor right away if the area of the blood draw swells or starts to produce pus.

Other minimal risks include:

Normal Thyroid Lab Tests But Still Have Hypothyroid Symptoms

This idea of optimal thyroid lab tests extends beyond just anti-TPO levels.

Unless you evaluate your thyroid lab tests entirely and with the optimal levels in mind, you will end up undertreated and may remain symptomatic.

Part of this problem is due to the reliance upon the TSH as the de-facto lab test to determine thyroid function.

The current treatment paradigm can be summed up in basically one sentence:

Give Levothyroxine or Synthroid to the patient and monitor the TSH to normal levels.

It turns out that thyroid hormone management is not quite that simple and several studies have shown that treating based on the TSH ultimately leads to low levels of T3, reduced quality of life and weight gain due to a slower metabolism .

When you look at all the data out there and our current treatment paradigm its easy to see why many hypothyroid patients go under-treated and misdiagnosed.

Because of these reasons, its very important to have a basic understanding of what defines optimal thyroid lab tests and use these values to determine the need for further management .

Part of the problem with diagnosing hypothyroidism is due to the bodys amazing ability to preserve serum thyroid levels under situations of extreme stress.

In addition, when it comes to hormones and serum levels, very small changes in blood levels can mean drastic changes in terms of function which results in symptoms in patients.

What The Results Mean

Blood test results are processed within a week. In some cases, doctors receive them within a few days. Your doctor will explain your specific results to you. A test that comes back as negative for antithyroid microsomal antibodies is considered a normal result. These antibodies are usually not found in a healthy immune system.

If you have an autoimmune disease or thyroid disorder, your antibody levels may rise. A positive test indicates an abnormal result and may be due to a variety of conditions, including:

  • Hashimotos thyroiditis, which is a swelling of the thyroid gland that often results in reduced thyroid function
  • Graves disease, which is an autoimmune disorder in which the thyroid gland is overactive
  • granulomatous thyroiditis, or subacute thyroiditis, which is a swelling of the thyroid gland that usually follows an upper respiratory infection
  • autoimmune hemolytic anemia, which is a drop in the number of red blood cells due to increased destruction by the immune system
  • nontoxic nodular goiter, which is an enlargement of the thyroid gland with cysts called nodules
  • Sjogrens syndrome, which is an autoimmune disorder in which the glands that produce tears and saliva are damaged
  • systemic lupus erythematosus, which is a long-term autoimmune disorder affecting your skin, joints, kidneys, brain, and other organs
  • difficulty with in vitro fertilization

How Much Does The Test Cost

Thyroid antibody test costs vary based on factors such as where the test is done, whether or not you have health care coverage, how many antibodies are tested for, and whether other tests are performed along with the antibodies test.

When ordered by a doctor, insurance typically covers the test, although you may have to pay a deductible or co-pay. Your doctors office, lab, and health plan can provide information about any out-of-pocket costs that may be your responsibility.

When Is It Ordered

Testing may be ordered when an individual has abnormal TSH and/or free T4 test results or signs and symptoms of a low or high level of thyroid hormones or the presence of a goiter, especially if the cause is suspected to be an autoimmune disease.

A low level of thyroid hormones can cause symptoms, such as:

  • Weight gain
Graves diseaseWhen a person has symptoms of hyperthyroidism

If a pregnant woman has a known autoimmune thyroid disease or has another autoimmune disorder and thyroid involvement is suspected, then one or more of the thyroid antibodies may be ordered early in the pregnancy and then again near the end. These tests are used to help determine whether the baby may be at risk of thyroid dysfunction. Thyroid antibodies can cross the placenta and cause hypothyroidism or hyperthyroidism in the developing baby or newborn.

Thyroid antibody testing may also be ordered when a person with another autoimmune disorder has symptoms of thyroid dysfunction and/or when she has reproductive difficulties that a healthcare provider suspects may be associated with autoantibodies.

Can Too Much Vitamin D Affect Thyroid

Thyroid peroxidase antibodies/thyroid peroxidase

A different gene in the Vitamin D receptor was shown to predispose people to autoimmune thyroid disease including Graves disease and Hashimotos thyroiditis. Vitamin D inhibits the production of Th1 polarizing cytokine , thereby indirectly shifting the polarization of T cells from a Th1 toward a Th2 phenotype.

Improve Your Gut Health

Preliminary evidence suggests that gut health is closely linked to thyroid health, and that improving gut health can decrease thyroid antibodies and balance your thyroid hormones. Here are several ways you can work on improving your gut health.

  • Anti-Inflammatory Diet: A low-quality diet is typically the single biggest source of inflammation that can impair your thyroid and immune function. But encouragingly, early evidence shows that changing your diet can lower thyroid antibodies.A low-carbohydrate diet was shown in one study to reduce thyroid antibodies by 44% in people with Hashimotos thyroiditis, but not celiac disease , while a gluten-free diet was shown to reduce thyroid antibodies in a group of women with Hashimotos thyroiditis . Other studies have shown that eliminating dairy or gluten may help improve thyroid function [6

What Is Peroxidase Test

Thyroid peroxidase , an enzyme normally found in the thyroid gland, plays an important role in the production of thyroid hormones. A TPO test detects antibodies against TPO in the blood. In autoimmune disorders, your immune system makes antibodies that mistakenly attack normal tissue.

Also asked, what is peroxidase and what does it do?

Antioxidant defenses, which can detoxify ROS, are present in plants. A major hydrogen peroxide detoxifying system in plant cells is the ascorbate-glutathione cycle, in which, ascorbate peroxidase enzymes play a key role catalyzing the conversion of H2O2 into H2O, using ascorbate as a specific electron donor.

What is peroxidase stain?

· dase stain. a method for demonstrating peroxidase granules in some neutrophils and in eosinophils the enzyme promotes the oxidation of benzidine by hydrogen peroxide tissues treated with horseradish peroxidase can also have the enzyme detected in the electron microscope.

What is the thyroid peroxidase?

Thyroid peroxidase oxidizes iodide ions to form iodine atoms for addition onto tyrosine residues on thyroglobulin for the production of thyroxine or triiodothyronine , the thyroid hormones. In humans, thyroperoxidase is encoded by the TPO gene.
