Introduction

Check the function of your thyroid gland. Thyroid disorders are common but often remain undiagnosed.

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.

It will give you a complete picture into whether your thyroid is functioning normally or not and will also give you an indication of whether you have an thyroid autoimmune condition which is one of the most common reasons for hypothyroidism.

How does this test work?

There is no better way to check for underlying health problems, or monitor existing conditions, than with a blood test.

Whether you are concerned about your health, managing an existing condition or simply curious, a blood test provides a fast, affordable and easy way to start taking charge of your own health.

We offer in-store testing to make the process as simple, stress free and convenient as possible.

You will receive your results on the day after we receive your sample in our laboratory. We run a 24/7 laboratory operation and test all samples as quickly as possible after receiving them which enables our team of in-house GPs to review and communicate your results in the fastest possible timeframe.

*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.

What do you test?

Thyroid (5 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

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 (thyroxine)

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.

Free T3

Free T3 (free triiodothyronine) is a hormone produced by the thyroid glands. This hormone is involved in several body functions including metabolism. It can be used to aid the diagnosis of thyroid diseases such as hyperthyroidism. Free T3 is commonly tested with Free T4 and TSH.

Antithyroglobulin antibodies

Antithyroglobulin Antibodies (Anti-Tg) are produced by the immune system as a defence mechanism to protect the thyroid against foreign invaders. Autoimmune condition will increase the amount of anti-Tg in the body, attacking healthy thyroid cells. Anti-Tg tests are used to diagnose thyroid disorders and are an indicator for autoimmune conditions.

Thyroid peroxidase antibodies

Thyroid Peroxidase Antibodies (Anti-TPO) are produced by the immune system as a defence mechanism to protect the thyroid against foreign invaders. Autoimmune condition will increase the amount of anti-TPO in the body, attacking healthy thyroid cells. Anti-TPO tests are used to diagnose thyroid disorders and are an indicator for autoimmune conditions.

FAQs

How often should I take a thyroid test?

You should take a thyroid test if you suffer from the above symptoms or are managing a mis-functioning thyroid.

What are other early warning signs of a thyroid problem?

Other symptoms of a potential problem with your thyroid may also include, sweating, tremors, trouble concentrating, hair loss, dry skin and puffiness of the face, hands or feet.

What is autoimmune thyroid condition?

This is when the body’s immune system attacks or overstimulates your thyroid, causing your thyroid to become overactive or underactive.

How is this test different from the Thyroid Function Baseline Profile?

This test includes all of the biomarkers covered in the Thyroid Function Baseline Profile, with the addition of antithyroglobulin and thyroid peroxidase antibodies. These antibodies simply check if you may have an autoimmune thyroid condition.
