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:

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.

Fasting and thyroid conditions can be compatible, if done correctly. The thyroid is a small, but extremely important gland in the human body. TheNational Institute of Health describes the thyroid as a 2-inch-long, butterfly-shaped gland weighing less than 1 ounce. Located in the front of the neck below the larynx, or voice box, it has two lobes, one on either side of the windpipe. The thyroid is one of the glands that make up the endocrine system. The glands of the endocrine system produce and store hormones and release them into the bloodstream. The hormones then travel through the body and direct the activity of the bodys cells. Can we fast with thyroid conditions? Lets take a closer look.

Thyroid conditions can have a tremendous impact on a persons health and are on the rise: Autoimmune thyroid affects millions, and oftentimes goes undiagnosed. According to theNational Cancer Institute, there were 53,990 estimated new cases of thyroid cancer in 2018, with rates for new cases rising on average 3.1% each year over the last 10 years. Death rates have been rising as well, 0.7% each year over 2006-2015.1

According to the National Institute of Diabetes and Digestive Kidney Diseases, other thyroid conditions are problematic as well: approximately 4.6 percent of the U.S. population ages 12 and over has an underactive thyroid 2, and 1 person out of 100 in the U.S. have an overactive thyroid 3.

Fasting is the quickest way to decrease cellular inflammation, because it allows the body to direct all of its energy towards healing. I say this with confidence because it has changed my life and made a greater impact on improving my cellular health than any other strategy.

In onestudy conducted on laboratory mice, researchers note that nuclear T3 levels are maintained at relatively normal levels in the pituitary of the fasted animal and fractional T3 receptor occupancy may actually increase.4

Anotherstudy comparing the levels of thyroid levels between impaired fasting glucose and impaired glucose tolerance found that fasting subjects had higher levels of F3, while those who were glucose impaired had lower levels of F3. Researchers concluded that the difference in thyroid hormone levels may play an important role in the different pathological mechanisms of IFG and IGT.5

As a person gets accustomed to fasting, the body gets more and more efficient with every subsequent fast. Fasting on a consistent basis can help reduce or even eliminate many of the ailments in todays society: cells become more efficient at utilizing fat, which burns cleaner than glucose. The body becomes more responsive to hormones. Brain fog dissipates, weight loss is easier, and most hormonal problems may be eliminated, and that includes thyroid conditions.

Thyroid Blood Test Normal Range

Almost twenty years ago, the American College of Physicians, a pretty conservative organization, stunned the medical community by issuing a guideline that women over 50 should have a thyroid test at least once every five years. At that time, most physicians thought that they could diagnose thyroid problems themselves and that testing guidelines were unnecessary.

In fact, a couple of years ago, Time Magazine reported that hypothyroidism is one of the top 15 leading conditions doctors most often get wrong.

Thyroid Function Test Results Explained

The thyroid usually changes slowly. It hardly ever quickly changes to being overactive or underactive: it usually takes a few weeks at least, or even a few months. If you have a thyroid function test that shows something is wrong, it’s usually worth repeating it in 3-6 weeks. That is because there’s always the chance that your thyroid gland could have gone back to normal by itself.

The second thing to bear in mind about thyroid function tests is that medications, and even herbal remedies or vitamin supplements, can affect the accuracy of thyroid results.

For these two reasons it’s always recommended to have a thyroid function test if it is recommended to you by a doctor, rather than having it done privately or without a doctor suggesting it.

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

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

Be aware that symptoms of thyroid dysfunction are easy to miss it is estimated that as many as 1 in 5 people may have sub-optimal thyroid function and do not even know it. So what should you look for? Here are some of the common thyroid symptoms I see in my patients.

Feeling Tired, Sluggish or Low Energy

Stomach/Digestion Concerns

You might be wondering what your thyroid has to do with your stomach, but your thyroid actually plays a role in healthy bowel function. If you feel bloated, constipated or have that heavy feeling in your stomach, your thyroid may not be functioning optimally. In this case, hypothyroidism can be ruled out. Conversely, if you experience excessive diarrhea, your thyroid may be overactive and hyperthyroidism should be considered.

Hair and Skin Changes

Mood Changes

Fertility Issues, Miscarriages and Menstrual Cycle Changes

Whenever one hormone is disrupted, there is often a disruption to other hormones up or down stream. If you are still menstruating, heavy, more frequent, or more painful periods can be a sign of hypothyroidism. Shorter, lighter or more infrequent menstruation may accompany hyperthyroidism.
