What is an advance thyroid test?

Every tenth person of the population is experiencing from one or the other thyroid problems, however usually, 60 to 70 percent of them never get to know their issues as a diagnosis. This happens because of either lack of getting tests done or because of complete thyroid function tests. Sometimes standard thyroid tests of T3, T4, TSH might not exactly give a clear picture of the thyroid troubles. Hence, it becomes hard for the physicians as well to identify and give a correct diagnosis for a disease.

Because thyroid gland has a great impact on overall metabolic rate, an effectively functioning thyroid can help in maintaining proper body weight, energy levels, sleep, body temperature, and brain development etc.

Low thyroid levels can negatively impact the body’s capacity for work, exercise and lot more. It makes maintaining proper thyroid function an essential component for fitness freaks to reach up to their goals of activity levels.

Unfortunately, the standard test available for testing of thyroid disorders only takes care of thyroid stimulating hormone (TSH) levels in major and its impacts however the Advanced Thyroid Function Blood Tests covers a wide range of aspects and provides a much clearer picture of the thyroid function.

It consists of several panels which include:

  • Total T3
  • Reverse T3
  • Free T3
  • T3 uptake
  • Total T4
  • Free T4 Index
  • Free T4
  • Thyroid Stimulating Hormone (TSH)

The process of advance testing is very easy. All the instructions will be given by the physician or the technician of any lab offline or online. You simply have to enroll yourself in the advanced testing procedure rest will be taken care of by the professionals. It even does not require any specific pre-test preparation you just have to follow the simple instructions shared with.


What is the problem with standard thyroid tests?

Any mainstream medical laboratory usually evaluates thyroid functioning by testing three main levels of T3, free T4, and TSH. It does not provide a whole coverage of the functionality of thyroid gland which misses over knowing the problems. Hence, diagnosis of the disorder can be missed. To avoid a miss of disorder prefer taking Advanced Thyroid Tests.

It helps in getting the right treatment plan and leads you to the path of wellness.

How can advance thyroid function tests help you?

A complete advance testing panel for thyroid includes the following tests:

Free T3:

This is the most active form of thyroid hormone amongst all. The body has to convert T4 into T3 to let you feel well. This becomes a near miss for “normal” and “feeling normal”. This conversion normally happens in the liver, kidney or even inside the gut. So in few cases, a thyroid problem might not be an actual thyroid issue but a trouble because of conversion issue of hormones. In that case, your liver, kidney or gut might be at fault. And treating thyroid with replacement hormone therapy will certainly not work in such cases. This will only be known if the free T3 test is done.

Total T3: 

This lab test reveals the total amount of metabolically active thyroid hormone available in the body. It further helps the physician to evaluate your body’s ability for conversion of T4 to T3 and ruling out any condition of an overactive thyroid.

T3 Uptake:

This test helps in knowing how much a body can us access the available T3. If a body accesses low level of T3 uptake then it indicates underlying causes like excess estrogen, high cortisol or stress hormone levels, inflammation, and even liver malfunction. All these prevent your body from accessing T3 levels. This test actually clears the picture of what beyond thyroid is affecting you. However, available standard tests fail to do so.

Reverse T3:

The body actually gets rid of unwanted T4 by converting it to reverse T3. High Reverse T3 levels indicate issues like a presence of high cortisol levels or chronic stress which needs attention.

Thyroid antibody:

High thyroid antibody presence reflects an autoimmune disorder instead of an actual thyroid disorder.

What are the reasons for thyroid issues beyond thyroid?

At times, patients with thyroid problems usually believe that their fatigue issues are probably because of the thyroid troubles. However, it is not always the case and the reason for fatigue can be something more than thyroid issues. Several factors can affect it like nutritional deficiencies, inflammation, food sensitivities, oxidative stress, and even adrenal or sex hormones can cause it. So knowing a little wider than just thyroid will be helpful.

Below is the list of certain tests which if done along with thyroid gives a far wide coverage of disease analysis:

  • Food sensitivity testing
  • Yeast or Candida testing
  • Complete urine hormonal profile test. This is essential to discover any cancerous issues relating to estrogen hormone and others
  • Complete nutritional testing to know about any deficiencies

thyroid function tests

  • Adrenal hormone analysis
  • Heavy metals testing
  • Toxic chemical exposure testing


The above specified extra tests become more essential in cases when drug therapies are not turning out effective for thyroid disorders. Since any underlying cause of it is not being taken care of.


In advance, thyroid tests panel consists of more tests to analyze thyroid malfunctioning than available in standard thyroid testing. It helps the physician to diagnose the thyroid disorder with ease as different levels of free and bound hormone levels are available in this. Sometimes panel even consists of tests of underlying diseases causing thyroid issues. Several different panels are available as per different labs. You need to pick one wisely to get the testing done.
