Free Thyroxine (T4)
Thyroxine (T4) is the hormone that has several important functions in the body, including speeding up the rate of metabolism, growth and energy levels. We test the thyroxine within the body to get an indicator of how well the thyroid is functioning. There are different treatments depending on if the thyroid is under or over the normal levels.
Free tri-iodothyronine (T3)
FT3 or free tri-iodothyronine is one of the two critical hormones produced by the thyroid gland. Its deficiency/excess is responsible for most of the thyroid related health issues because of its stronger impact even though it constitutes the lesser fraction as compared to the other hormone, FT4. Menopause blood test detects the amount of FT3 which is not attached to a protein and help to understand thyroid functioning.
Thyroid peroxidase antibodies (TPOAb)
Thyroid peroxidase (TPOAb) is an enzyme that converts T4 in to the active T3. The TPO test analyses if antibodies are attacking the thyroid gland and impairing its function.
Vitamin D
Vitamin D is a vitamin that's essential for many functions in your body, including bone and muscle health. Vitamin D can be found in food, supplements, and fortified foods. If you don't get enough vitamin D, you may develop osteoporosis or muscle weakness. An average vitamin D level is 20 to 50 ng/mL. If you have a low vitamin D level, we may recommend that you take a vitamin D supplement or eat foods fortified with vitamin D.
Active Folate
Folate is the naturally occurring form of the vitamin B9. It acts as a coenzyme in the metabolism of amino acids. Folate is important in the synthesis of purines and pyrimidines as well as during the first trimester of a pregnancy
Thyroid stimulating hormone (TSH)
TSH (Thyroid Stimulating Hormone) or thyrotropin is secreted by the pituitary gland, located in the head, and can help identify cases of hypothyroidism and hyperthyroidism. Both the excess and under-secretion of TSH can lead to weight loss, anxiety, palpitations, irregular sleep patterns and irregular menstrual cycles. Hypothyroidism is majorly associated with overlapping symptoms such as menopause.
Thyroglobulin antibodies (TgAb)
The thyroglobulin protein (TgAb) is produced in the thyroid gland. It makes hormones T3 and T4 which aid in the control of metabolism, growth and mood wings. The test is done to check the level of antibodies that the body has made in response to the compound thyroglobulin.
Ferritin
Ferritin is the protein that stores iron in the body. Iron is needed to provide muscles with oxygen so that they receive the energy they need to function properly. Ferritin will release the iron when needed and is kept within the body's cells, most commonly found in the liver. We check ferritin levels to ensure that there is proper storage of iron in the body's cells otherwise the iron will be depleted quickly.
Vitamin B12
Vitamin B12 is a water-soluble vitamin that can be naturally present in foods or as supplements. The b12 vitamin aids in the production of red blood cells that carry oxygen around the body. It also plays a role in the development and function of the nervous system.
C-Reactive Protein (CRP) HS
The C-Reactive Protein (CRP) is a protein produced in the liver. The CRP protein is found within the blood and will increase in numbers when there is an injury or illness. The High Sensitivity CRP test aims to detect any low-level inflammation which may damage blood vessels, leading to a heart attack or stroke.

Additional Insight from Dr Sameer Nakedar, MBBS, MRCGP, PGCert
"Some vitamins and minerals support your thyroid function; therefore, getting optimal vitamins helps. However, abnormal levels of specific vitamins can also cause various symptoms, sometimes similar to thyroid disorders. Understanding these vitamin and mineral levels can help identify or exclude a cause for these symptoms.
The advanced check also includes inflammatory markers. In some situations, thyroid disorders are caused by autoimmune disorders, meaning the body’s natural defence system (the immune system) is not functioning adequately. In some cases, thyroid disease is a result of autoimmune problems."

Experts Opinion
"A basic thyroid function test can help you understand if your thyroid function is normal, overactive, or underactive. The advanced check also includes inflammatory markers. In some situations, thyroid disorders are caused by autoimmune disorders, meaning the body’s natural defence system (the immune system) is not functioning adequately. In some cases, thyroid disease is a result of autoimmune problems."
