Plus Blood Test
Our advanced thyroid profile takes a detailed look at your thyroid function including antibodies as well as thyroid nutrition for optimum thyroid health.
Thyroid Check UltraVit Blood Test
About this test – Why take the Thyroid Blood 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
This advanced thyroid profile contains everything you need to give you a clear picture of your thyroid health. This profile includes Thyroid Blood test for TSH, thyroid hormones (FT4 and FT3) and thyroid antibodies (thyroglobulin antibodies and thyroid peroxidase antibodies) for a thorough investigation of thyroid function and autoimmune disorders which could be causing your symptoms. Importantly it tests for free triiodothyronine (FT3) to see how well you are converting thyroxine (FT4) to the more biologically active FT3.
This profile includes vitamins and minerals which not only support your thyroid function but which can also mimic the symptoms of an underactive thyroid if they are found to be low. We include tests for vitamin D, vitamin B12 and folate (vitamin B9) and ferritin (a marker for iron storage). We also include an inflammation marker to help interpret your iron (ferritin) result as well as give a picture of whether an autoimmune condition is causing inflammation in your body.
All our results come with doctor’s advice included – you will receive personalised results with recommendations about what to do next.
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).
How it Works:
Order your test. We will arrange for one of our trained phlebotomists to take your sample and send it to our accredited laboratory.
We will email you with your results within the specified turnaround times.
Our tests are not a substitute for seeing your doctor, especially if you are suffering symptoms. We can arrange to have your results interpreted based on the information you have provided, but will not diagnose, consult or provide any treatment. (This incurs an additional cost and will need to be requested at time of ordering).
You will be advised to see your doctor.
