Advanced Thyroid Test with Reversed T3


The Advanced Thyroid Test with Reversed T3 is the most comprehensive test used in Functional Medicine to understand the whole picture of the Thyroid.

This test offers not only the complete picture of thyroid hormones, but also it’s cofactors. Other markers included are: B12, Folate, Vitamin D and Ferritin. All of these makers are essential for healthy thyroid function. Everything in the body works in synergy, therefore it is essential to have nutrients or cofactors at the optimal levels simultaneously.

Thyroid Hormones in the Advanced Thyroid Test

TSH test:

When your thyroid is not producing sufficient levels of thyroid hormone, your pituitary gland sends out thyroid-stimulating hormone (TSH) to encourage the thyroid to increase production. That’s why the most common way to diagnose thyroid dysfunction is by measuring how much TSH your pituitary gland excretes. The higher your level of TSH, the more likely you are to have hypothyroidism. However the TSH test its only one of multiple markers we should consider.

T4 and T3 test:

The thyroid produces two important hormones called T3 (triiodothyronine) and T4 (thyroxine). The building blocks of thyroid hormone are amino acids and iodine ions. Considering these hormones in addition to TSH gives a better picture of your thyroid function.

When you have hypothyroidism, your thyroid doesn’t produce enough of the thyroid hormones T3 or T4 (or both). On the contrary, hyperthyroidism is when the body has too much of these thyroid hormones. Thyroid hormones have an effect on all tissues including growth and development of tissues, metabolism of nutrients, energy production etc.

Antibody tested are TPO (thyroid peroxidase) and TG (thyroglobulin).

None or very low presence of antibodies is normal for a healthy thyroid function, however if they are raised it means that thyroid is attacked by the immune cells. When this happens an autoimmune condition is diagnosed. Thyroid is unable to keep up with the destroyed tissue and its function decreases. One can live with undiagnosed raised antibodies for years and even decades. Often the antibodies are not tested in the routine check-up unless asked and insisted for.

Testing for antibodies is essential because a different health approach has to be undertaken if they are raised.

Reverse T3 Thyroid Test in Advanced Thyroid Profile:

The Reverse T3 test is recommended by Functional Medicine Practitioners to observe deeper how thyroid biochemistry works on the cellular level. It gives a more comprehensive picture of metabolism within the cells.

When our body is under any kind of trauma or stress, for example after illness or malnutrition, the normal conversion of Thyroxine (T4) to Triiodothyronine (T3) can be interrupted. The available T4 instead will be converted to rT3 in the cells to slow down metabolic processes.

When rT3 rises this could indicate that the cell slows the metabolic processes in the body. The rT3 marker can explain why with normal TSH, T3 and T4 we can experience all the symptoms of underachieve thyroid (Hypothyroidism).

The Reversed T3 test is an extra tool to use in the clinical practice to help the practitioner to understand better the biochemistry and create more tailored approach to eradicate or minimise clients symptoms.

This test can be done only through a private laboratory company, because the GP don’t consider this marker as it doesn’t affect in anyway the allopathic treatment, in contrast to Functional Medicine Approach.
