Thyroid Monitoring Blood Test

About this test – Why take this test?

  • You have symptoms which you think may be caused by an overactive or underactive thyroid

     

  • You want to test both your thyroxine (T4) and your triiodothyronine (T3) to check that you are converting properly

     

  • You are taking thyroid medication and you want a regular check of your hormone levels

This monitoring profile is an excellent test to assess thyroid function. It includes thyroid stimulating hormone (TSH) as well as free T4 (FT4) and free T3 (FT3). Most thyroid hormones are bound to proteins in the blood. This test measures the level of free or unbound thyroid hormones which are either available to be converted or are biologically active.

TSH is produced by the pituitary gland to stimulate the thyroid to produce thyroid hormones (mostly T4). An elevated TSH often signifies that the thyroid is struggling to produce enough T4 for the body’s needs. TSH on its own does not necessarily give a true picture of your thyroid function which is why we test both forms of thyroid hormone too.

Thyroid Function

Thyroid Stimulating Hormone (TSH) is produced in the pituitary gland and stimulates the thyroid gland to produce thyroid hormones thyroxine (T4) and triiodothyronine (T3).

High levels of TSH indicate an underactive thyroid while low levels indicate an overactive thyroid. In primary pituitary failure, a low TSH will be associated with an underactive thyroid.

Thyroxine (T4) is one of two hormones produced by the thyroid gland. Most T4 is bound to carrier proteins in the blood. This test measures the level of T4 which is free, or unbound, circulating in your blood.

High levels of free thyroxine can indicate an overactive thyroid while low levels can indicate an underactive thyroid.

Triiodothyronine (T3) is one of two thyroid hormones produced by the thyroid gland. Most T3 is bound to protein in the blood. Free T3 measures the level of T3 that is free, or unbound to protein, and is available to regulate metabolism.
