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.

How do the tests work?

There is no better way to check for underlying health problems, or monitor existing conditions, than with a blood test. From our dedicated, state-of-the-art laboratory in London we offer the latest in pathology testing solutions across many disciplines including biochemistry, immunology, haematology, sexual health screening and molecular biology.

*It is important to note that blood tests alone are not a substitute for seeing a doctor, particularly if you have any symptoms. You should not make a diagnosis or start any treatment without a consultation with a doctor or suitably trained healthcare professional. 

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

Biomarker Profiles

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.

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.

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 Free T3 and TSH.

FAQS

The thyroid gland produces essential hormones that are carried to all parts of the body via the blood stream. This is especially important in regulating your metabolism which can directly affect the function of your brain, heart rate and body temperature.

Other symptoms may also include trouble concentrating, hair loss, dry skin and puffiness of the face, hands or feet.

Our normal measurement range is between 0.3 - 3.05 for TSH and between 9 - 23 for thyroxine. If our medical consultants observe any abnormal results then they will notify you within result certificate, and recommend how you may want to raise this with your doctor.

You do not need to fast before the test itself. Inform your doctor if you are on any medications as some may impact your thyroid function. If you have had recent imaging with contrast dye that may contain iodine this can also affect your results. If you are pregnant let the doctor know as this can also impact results
