What can I expect from Thyroid Function - Diagnosis and Monitoring?
This profile checks the function of your thyroid gland. Thyroid disorders are common but often remain undiagnosed. It will give you a good indication as to whether your thyroid is functioning normally or not by checking your levels of Thyroid Stimulating Hormone (TSH) and Free T4 (FT4).
These tests are mainly used to see whether or not you have an underactive thyroid gland (Hypothyroidism) or an overactive one (Hyperthyroidism) which can lead to tiredness, mood problems and weight issues.

Who should take a thyroid blood test and when?
This test is best taken if you have symptoms of hyperthyroidism (overactive thyroid) or hypothyroidism (underactive thyroid).
Symptoms of hyperthyroidism include unexplained weight gain/loss, sweating, tremors, heat sensitivity and loss of libido. It is more likely to occur with age—particularly over the age of 60—and among women.
Signs of hypothyroidism can include tiredness, dry skin, decreased appetite, memory loss and poor concentration. Hypothyroidism is more likely to occur with older age and among pregnant women.
People with certain conditions are also much more likely to develop thyroid problems and should get tested regularly, this includes:
Type 1 Diabetics / Addison’s disease / Coeliac Disease / If you are on certain medications e.g Lithium and Amiodarone

Thyroid (2 Biomarkers)
Thyroid disorders are common but often remain undiagnosed. If your thyroid isn't functioning properly, it can cause tiredness, mood problems and weight issues.
Free T4 (free thyroxine) is a hormone produced by the thyroid gland. This hormone is involved in several body functions including metabolism and growth. It can be used for the diagnosis of thyroid diseases such as hypothyroidism or hyperthyroidism as well as aiding the diagnosis of female infertility problems. Free T4 is commonly tested with TSH.
Thyroid Stimulating Hormone (TSH) are made by the pituitary gland in the brain to stimulate the thyroid gland (located by the throat). The hormones that are produced are used to regulate weight, body temperature and muscle strength. Levels of TSH are measured as it is an indicator of thyroid disease and is commonly tested with Free T4 and Free T3.
