Normal Thyroid Levels

ThyroSynergy Natural Thyroid Health Formula

What Are The Best Thyroid Function Tests?

A thyroid function test will reveal if your thyroid hormones are considered to be within 'normal thyroid levels'. A thyroid blood test is used to assess levels of the major thyroid hormones in your bloodstream. The three main hormones tested include; thyroid stimulating hormone (TSH), thyroxine (T4) and triiodothyronine (T3).

TSH is accepted as the first line test to assess thyroid function. TSH is produced by the pituitary gland and tells the thyroid gland to manufacture and release more T4 and T3.

The reference ranges used by pathology labs are derived from average values in the whole population. Having a result in the reference range does not always prove a healthy thyroid state. You should also consider the signs and symptoms of an underactive thyroid.

The standard references listed here are used by Australian pathology labs. If you are outside of Australia you may have different reference ranges. Please discuss these with your health practitioner.
