Thyroid Check Ultra Blood Test

About this test

This profile includes tests for TSH, thyroid hormones (FT4 and FT3) and thyroid antibodies (thyroglobulin antibodies and thyroid peroxidase antibodies) for a thorough investigation of your thyroid status and autoimmune disorders which could be causing your symptoms. 

It also includes tests for iron storage (ferritin) which can be low in individuals with thyroid disease, key nutrients folate and vitamin B12, as well as an inflammation marker (high-sensitivity C-Reactive protein).

Who is this test for?

This test is for individuals who want a thorough examination of thyroid function and nutritional status. 

 

How it Works:

Sample

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.

Important Information:

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). 

Vitamins

Vitamin B12 is important for production of red blood cells which carry oxygen around the body – low levels can cause anaemia with associated symptoms of lack of energy and fatigue. It is also important in metabolism and for the nervous system and prolonged lack of vitamin B12 may cause nerve damage. Vitamin B12 is almost entirely found in meat and animal food products.

Around 70% of vitamin B12 is bound to carrier proteins in your blood. This test measures the level of unbound or active B12 which is available for your cells.

A common reason for elevated B12 is over-supplementation. Raised levels of vitamin B12 may indicate a blood or liver disorder.

Low levels are seen in people with pernicious anaemia, an autoimmune disease which prevents the absorption of vitamin B12, or anyone who suffers from absorption problems such as the elderly, people with inflammatory bowel conditions and alcoholics. Vegetarians and vegans can also be low in vitamin B12, especially if they don’t consume foods which have been fortified with vitamin B12 or take B12 supplements.

Folate is a water soluble vitamin which is needed by the body in your diet every day. It plays a role in DNA replication and protection, it’s important for the production of red blood cells as well as in the prevention of neural tube defects in babies.

Low levels can indicate anaemia and can be implicated in raised homocysteine levels.

Inflammation Marker

C-Reactive Protein (CRP) is an inflammation marker used to assess whether there is inflammation in the body – it does not identify where the inflammation is located. High Sensitivity CRP (CRP-hs) is a test which is used to detect low-level inflammation which is thought to damage blood vessels which can lead to a heart attack or stroke. 

Raised levels are a risk factor for cardio-vascular disease. 

Iron Status

Ferritin is a protein which stores iron in your cells for your body to use later. Measuring ferritin levels gives us a good indication of the amount of iron stored in your body.

Low levels of ferritin can indicate anaemia which can be caused by excessive or chronic bleeding, poor absorption of iron or too little iron in the diet. 

Raised ferritin levels can indicate iron overload syndrome (haemochromatosis) or any kind of liver damage. It is also a marker of infection and inflammation.
