Is Your Doctor Missing This Important Test?

Thyroid disease affects one in five women and one in ten men, yet 50 percent of people with thyroid disease go undiagnosed.

The main role of thyroid hormone is to stimulate metabolism, affecting almost every function of the body. That’s why thyroid imbalance can cause so many different symptoms.

Now, doctors typically diagnose thyroid problems by testing your thyroid-stimulating hormone or TSH levels – the ideal range being between 1 and 2 m IU/ml – and sometimes your free T4 level.

However, some doctors and clinicians are questioning the “normal” levels of those tests. To get a more complete picture, I recommend looking at a wider range of functions:

– Thyroid-Stimulating Hormone (TSH)
– Free Triiodothyronine (T3) Thyroxine (T4) – The inactive and the active hormones, respectively.
– Thyroglobulin Antibodies (TgAb) and Thyroid Peroxidase Antibodies (TPO) – When other thyroid test results come back as normal, most doctors don’t routinely check this. However, this test looks for an autoimmune reaction that commonly goes undiagnosed.
