Key Points About Hashimotos Thyroiditis
- Hashimotoâs thyroiditis can cause your thyroid to not make enough thyroid hormone.
- It is an autoimmune disease. It occurs when your body makes antibodies that attack the cells in your thyroid.
- Symptoms may include an enlarged thyroid gland , tiredness, weight gain, and muscle weakness.
- You dont need treatment if your thyroid hormone levels are normal. If you have an underactive thyroid, medicine can help.

What Are Thyroid Function Tests
Thyroid function tests are a series of blood tests used to measure how well your thyroid gland is working. Available tests include the T3, T3RU, T4, and TSH.
The thyroid is a small gland located in the lower-front part of your neck. Its responsible for helping regulate many bodily processes, such as metabolism, energy generation, and mood.
The thyroid produces two major hormones: triiodothyronine and thyroxine . If your thyroid gland doesnt produce enough of these hormones, you may experience symptoms such as weight gain, lack of energy, and depression. This condition is called hypothyroidism.
If your thyroid gland produces too many hormones, you may experience weight loss, high levels of anxiety, tremors, and a sense of being on a high. This is called hyperthyroidism.
Typically, a doctor who is concerned about your thyroid hormone levels will order broad screening tests, such as the T4 or the thyroid-stimulating hormone test. If those results come back abnormal, your doctor will order further tests to pinpoint the reason for the problem.
If youre concerned about your thyroid function and dont already have a primary care doctor, you can view doctors in your area through the Healthline FindCare tool.
There are also at-home thyroid function tests available from LetsGetChecked and Everlywell. Healthline has also created a list of best at-home thyroid tests here.
Fasting And Thyroid Health: Check Your Hormones
There are three important hormones that are key to thyroid health: TSH, T3, and T4. These hormone levels can appear normal when checked, but they hold the key to potential thyroid conditions. All of these can be altered for the better through the art of fasting:
All of these potential reasons for thyroid dysfunction can be helped through fasting.

What Is The Thyroid
Located on the lower part of the front of the neck, the thyroid is a butterfly-shaped gland that measures two inches in length. For men, the gland is located underneath the Adams apple, near the windpipe.
The thyroid, which is part of the endocrine system, is responsible for the metabolism.
When there are no issues with the thyroid, and its a normal size, it cannot be felt however, when it doesnt work right, it may become enlarged or could grow lumps of extra tissue.
Thyroid Hormone Level Tests
There are four main thyroid hormones that have been identified: T1, T2, T3, and T4.
T4 and T3 are the two main thyroid hormones. T4 is known as prohormone and is 300 percent less biologically active than T3. T3 is the main biologically active thyroid hormone and gives us beautiful hair, replenishes our energy, and runs our metabolism.
You may have put together that most of the commonly prescribed thyroid medications like Synthroid and levothyroxine, only contain T4 , and thus they need to be converted to the active T3 form in the body.
On paper, the T4 to T3 conversion happens just fine, but in the real world, in real human bodies, we may not always convert T4 to T3.
We can reveal our T4 to T3 ratios and measure the hormone that is available to do its job in the body, by testing our free T4 and free T3 levels.
Free T3 and Free T4 tests measure the levels of active thyroid hormone circulating in the body.
Some clinicians may only test for T4, but T3 is also important to test, as some individuals may not be converting T4 to the active T3 properly. Thus, people may have a normal T4, but a low T3 level.
How Do You Know If You Are Converting Correctly?
Take a look at your free T3 and free T4 levels. Both should be in the optimal ranges noted below, which have been determined by functional medicine guidelines and my clinical experience. If the T4 is optimal, but the T3 is below the optimal range, you know that your body is not making enough T3 hormone from the T4.

Full Thyroid Panel With Antibodies
A full thyroid panel with antibodies is useful for diagnosing hyperthyroidism caused due to autoimmune thyroiditis. Thyroiditis is a condition that causes inflammation of the thyroid gland. Autoimmune thyroiditis causes the antibodies to attack the thyroid gland by mistake. The symptoms of thyroiditis are fatigue, muscle weakness, weight gain, and an enlarged thyroid gland .
Why Consider This Test
Specific Thyroid Concerns
Tests that measure both TSH and T4 can be used together to screen for and help diagnose thyroid conditions, including hypothyroidism and hyperthyroidism .2
Female Health and Fertility
Women are five to eight times more likely than men to have thyroid problems. Hypothyroidism is a leading cause of difficulty in achieving and maintaining pregnancy.2
Undiagnosed thyroid disease may put patients at risk for certain serious conditions such as cardiovascular diseases, osteoporosis, and infertility. Most thyroid conditions can be managed with medication.2

What Tests Do Doctors Use If I Have A Thyroid Nodule
If your health care professional finds a nodule or lump in your neck during a physical exam or on thyroid imaging tests, you may have a fine needle aspiration biopsy to see if the lump is cancerous or noncancerous.
For this test, you will lie on an exam table and slightly bend your neck backward. A technician will clean your neck with an antiseptic and may use medicine to numb the area. An endocrinologist who treats people with endocrine gland problems like thyroid disease, or a specially trained radiologist, will place a needle through the skin and use ultrasound to guide the needle to the nodule. Small samples of tissue from the nodule will be sent to a lab for testing. This procedure usually takes less than 30 minutes. Your health care professional will talk with you about the test result when it is available.

Thyroid Testing: How It Works
Thyroid tests use a blood sample to measure various hormone levels. Thyroid-stimulating hormone , for example, is often measured to indirectly check if your thyroid gland is producing enough thyroid hormones. TSH levels are usually higher than normal in TSH test results if you have an underactive thyroid.
Thyroid gland function tests can also measure thyroid hormones like thyroxine to provide a better understanding of how low â or how high â your thyroid hormone levels are.

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.
This is an important test that I recommend getting every time you check your thyroid function.
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 signal 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 under- or overmedicating them!
Most conventional practitioners will stop further thyroid testing when they determine the TSH is normal .

How Do You Know If A Thyroid Test Kit Is Reputable
First, its important that the test kit itself is certified by Clinical Laboratory Improvement Amendments , which ensures quality laboratory testing. Youll also want to check if they are certified by the College of American Pathologists , which ensures best practices regarding obtaining accuracy of test results and meeting other important required standards.
According to Dr. Shah, The lab Paloma Health uses is a CLIA and CAP-certified lab, government-certified at the gold standard of the lab industry. The labs are tested versus commercially available labs to be equivalent in their results.
The same goes for other test kits made by other companies: Other services who use CLIA- and CAP-certified labs will also provide accurate readings, she says.
Dr. Shapiro also recommends asking your endocrinologist or healthcare provider if they can recommend a reputable thyroid test kit.
The good news is that at-home test kits, when bought by a reputable provider, are generally very reliable. According to a study in the Journal of Medical Screening, they offer accurate and inexpensive testing.
Free T4 By Lmmulite Or By Equilibrium Dialysis
Measurement of free T4 with a valid assay can be useful for diagnosis of true hypothyroidism and differentiating it from the euthyroid sick condition. Euthyroid sick dogs may have low T3 and /or T4 levels due to other non-thyroid factors . Free T4 is the non-protein bound thyroxine and it is present in lower concentrations in the blood than total T4. For accurate FT4 testing the procedure should have a method for separating the protein bound hormone from the free hormone.
The Equilibrium Dialysis method uses an overnight incubation in buffer and dialysis cells to separate the bound T4 from the free. The Immulite method uses a very specific antibody. The Immulite method is faster and less expensive than the ED method and for dogs it produces results that are comparable to the dialysis method. The lmmulite method will be used for all canine FT4 testing in this lab, unless ED is specifically requested. FT4 should be used to monitor thyroid supplementation in any dog known or suspected to have thyroid autoantibodies , as these tests remove the autoantibody effects.

Thyroid Antibodies You Are Most Likely To Test Positive For
Many of you have read about thyroid antibodies Antibodies protein produced in the blood that fight diseases by attacking and killing harmful bacteria , or seen them mentioned in your blood tests. Because it sounds pretty technical, some of us get a bit confused about the whole thing so here is an explanation.
You know that the body produces antibodies as part of a normal immune response to foreign invaders, like viruses and bacteria. It happens that certain body proteins Proteins plant or animal tissue , going peacefully about their business, can get attacked by the immune system Immune system the organs and processes in the body that work together to resist infections , even if they have done nothing wrong. When this happens the body cells being wrongly attacked can be damaged and destroyed. This can happen in a number of ways, but we, of course, are most interested in the thyroid.
What Blood Tests Do Doctors Use To Check Thyroid Function
Doctors may order one or more blood tests to check your thyroid function. Tests may include thyroid stimulating hormone , T4, T3, and thyroid antibody tests.
For these tests, a health care professional will draw blood from your arm and send it to a lab for testing. Your doctor will talk to you about your test results.

Comparing High/low Tsh And T3/t4 Levels
- Normal TSH + normal T4 = normal thyroid function
- High TSH + normal T4 = you may have a higher risk of developing an underactive thyroid
- Low TSH + high T4 = overactive thyroid
- High TSH + low T4 = underactive thyroid
- Low TSH + low T4 = low thyroid function due to another problem, such as pituitary gland dysfunction
Looking at TSH alongside T3 test results can also help with diagnosis:
- Low T3 + high TSH = low thyroid function
- High T3 + low TSH = overactive thyroid
