Thyroid Comprehensive Test

What this test measures
Read more about the health markers we check in this blood test

Thyroid Hormones

TSH Learn More

Thyroid Stimulating Hormone (TSH) is produced by the pituitary gland and acts to increase the functioning of the thyroid gland, This stimulation in turn encourages the production of triiodothyronine (T3) and thyroxine (T4) by the thyroid. Elevated TSH may be indicative of an underactive thyroid, In comparison, reduced TSH may be associated with an overactive thyroid.

FT4 Learn More

The purpose of this test is to measure the amounts of free thyroxine (T4) that is present within the blood. T4 is a one of two hormones that is secreted by the thyroid gland. Therefore, a high result may be associated with an individual with an overactive thyroid as more T4 is produced then normal. In contrast, a lower than normal result may arise if an individual has an underactive thyroid.

FT3 Learn More

The purpose of this test is to measure the amounts of free thyroxine (T3) that is present within the blood. T3 is a one of two hormones that is secreted by the thyroid gland (the other being T4). Therefore, a high result may be associated with an individual with an overactive thyroid (hyperthyroidism) as more T3 is produced then normal.

Autoimmunity

TGAb Learn More

Thyroglobulin (TG) is a protein that is found within the thyroid gland where it is required for the production of the hormones triiodothyronine (T3) and thyroxine (T4). This test evaluates the levels of antibodies against TG that are present within the blood. As antibodies against TG (TGAb) typically only arise following inflammation or attack of the thyroid by the body's immune system, elevated levels may be indicative of an autoimmune disorder that may result in the impairment of normal thyroid functioning.

TPOAb Learn More

Thyroid peroxidase (TPO) is an enzyme that can be found within the thyroid gland where it is involved in the conversion of thyroxine (T4) to triiodothyronine (T3). This test evaluates the levels of antibodies against TPO that are present. A high value of antibodies against TPO (TPOAb) can indicate the body has mounted an immune response against the thyroid gland leading to its attack and potential damage. This may be indicative of an autoimmune disorder where the functioning of the thyroid may be impaired. Examples of such autoimmune disorders include Hashimoto's disease which is associated with an underactive thyroid and Graves disease which is associated with an overactive thyroid.

Vitamins

Vitamin B12 (active) Learn More

Vitamin B-12 is an important vitamin that is involved in several processes ranging from the production of red blood cells to aiding in the correct functioning of the nervous system. Consequently, prolonged vitamin B12 deficiency can result in anaemia or nerve damage respectively. In contrast, elevated levels of vitamin B12 can be an indication of a liver or blood disorder. The most common cause of raised vitamin B12 is due to over supplementation.

Folate Learn More

Folate is a type of B vitamin that is involved in several processes from the production of red blood cells to the production and repair of DNA. Individuals mainly receive folate from their diet therefore, a lack of folate within the diet can result in folate deficiency. Low levels may also be indicative of anaemia.

Vitamin D Learn More

Interestingly enough, vitamin D is in fact a hormone that is produced by the body and requires exposure to sunlight for activation. In addition. it can be found in certain foods such as egg yolks, fish and fortified dairy and grain products. Vitamin D is an essential component required for maintaining bone strength due to its role in aiding the intestines ability to absorb calcium. Low levels of vitamin D may be associated with secondary low bone mineral density and hyperparathyroidism. Consequently, these patients have a greater risk of suffering fractures and osteoporosis. Other conditions such as rickets and osteocalcin may also develop as a result of continued vitamin D deficiency over a long period of time.

Inflammation Marker

hs-CRP Learn More

C-Reactive Protein (CRP) is a protein that increases in response to inflammation detected within the body - though it cannot be used to identify the exact location of where this inflammation is occurring. On the other hand, high Sensitivity CRP (hs-CRP) is used to detect low-level inflammation and can give more of an indication of the location of the inflammation as this type has been found to be associated with damaged blood vessels. Damage to blood vessels can increase an individuals likelihood of suffering a stroke or heart attack. Therefore, an elevated hs-CRP may be considered a risk factor for cardio-vascular disease.

Iron Status

Ferretin Learn More

Ferritin is a protein that stores iron and releases it in a controlled fashion. In humans, it acts as a buffer against iron deficiency and iron overload. Plasma ferritin is also an indirect marker of the total amount of iron stored in the body, hence serum ferritin is used as a diagnostic test for iron-deficiency anaemia. Low levels are indicative of anaemia and may be caused by events such as excessive bleeding or lack of iron within the diet. In contrast, elevated ferritin levels could indicate iron overload syndrome or liver damage.

About this test and how it can help you

This is our most complete and advanced package we offer to assess the health of your thyroid as well as investigate other potential causes for your symptoms.

The thyroid is a small gland that is located towards the lower front of your neck. The thyroid secretes hormones which are important in regulating many processes within the body including growth, development, metabolism, body temperature and heart rate. The two main hormones produced by the thyroid are triiodothyronine (T3) and thyroxine (T4). If for any reason, the thyroid gland fails to produce the correct amounts of these hormones you may experience symptoms associated with a thyroid disorder. This may include one of more of the following:

  • Weight loss or weight gain
  • Fatigue and tiredness
  • Depression
  • Tremors
  • Excessive anxiety

In addition to testing for; thyroid stimulating hormone (TSH), free T3 (FT3) and free T4 (FT4) that assess thyroid function we also test for antibodies against the thyroid (thyroid peroxidase antibodies and thyroglobulin antibodies). The presence of these antibodies can help diagnose if an autoimmune disease is the cause of your symptoms. Testing for high-sensitivity C-Reactive protein also helps identify inflammation in the body and establish whether this is being caused by an autoimmune disease. Iron status is also investigated as this may be reduced if you have a thyroid disorder. Further to this, we evaluate your levels of key vitamins including; vitamin D, vitamin B12 and folate. This is important as these nutrients help support the normal functioning of the thyroid. A lack of these vitamins can also contribute to fatigue and other symptoms that may be associated with an underactive thyroid.
