Thyroid Check Plus

About this test

Why take this test?

  • you want to check symptoms of an underactive or overactive thyroid
     
  • you want to test how well you are converting thyroxine (T4) into the more active thyroid hormone triiodothyronine (T3)
     
  • you want to understand whether autoimmune disease could be the cause of a thyroid disorder

Many people begin their investigation into a potential thyroid condition with our Thyroid Check Plus. It offers a comprehensive investigation into the main thyroid hormones (TSH, FT4 and FT3) as well as thyroglobulin antibodies and thyroid peroxidase antibodies.

Thyroid conditions are very common but can be difficult to diagnose - many of the symptoms of a thyroid disorder can be overlooked (especially if they are mild) or confused with other conditions. This test offers an affordable insight into what could be causing your symptoms by checking your levels of thyroid stimulating hormone (TSH), which is often abnormal in thyroid disease, free thyroxine (FT4) and free triiodothyronine (FT3). By measuring the amount of thyroid hormone that is "free" or unbound to carrier proteins in the blood, we can get a better picture of how much thyroid hormone is available to your cells. 

Many thyroid disorders are caused by an autoimmune disease and your risk for this is raised if you or a family member has a history of autoimmune disease. This test looks for specific thyroid antibodies which can indicate that your thyroid is under attack from your immune system.

Tests Included

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.

This test looks for antibodies to thyroglobulin, a protein which is specific to the thyroid gland. Under normal circumstances it does not enter the bloodstream, but if your thyroid is inflamed or under attack from the body's own immune system, then thyroglobulin can be secreted and antibodies detected. 

Raised levels of thyroglobulin antibodies (TGAb) can indicate autoimmune thyroid disease. 

Thyroid peroxidase is an enzyme which is produced in the thyroid gland and is important for converting T4 to the biologically active T3. This test looks for antibodies to thyroid peroxidase (TPOAb) in the blood which indicates that the body's immune system is attacking the thyroid gland and impairing its function. 

Raised levels of thyroid peroxidase antibodies are often found in Hashimoto's disease (underactive thyroid) and can sometimes be detected before any symptoms are reported. 

Raised levels are also found in over half the cases of Graves' disease (overactive thyroid).
