Frequently Asked Question
What can I expect to happen?
When you attend your appointment the nurse will ask you some basic medical questions to ensure you are well enough for the blood test. Your screen will consist of a blood sample, usually from your arm.
Do I need to prepare?
There is no need to fast (go without food or drinks) for this test.
We do suggest keeping your arm warm, as being cold can sometimes make it harder to draw your blood, and stay well hydrated.
If blood tests make you anxious, let your nurse know at the start of your appointment. They will do their best to make the experience as stress-free as possible.
What you’ll be tested for
Thyroid-Stimulating Hormone (TSH) – measured with T4 and FT3 this gives an idea of if the thyroid hormones are in balance, helping to detect an underactive (hypothyroidism) or overactive (hyperthyroidism) thyroid and the impact of any drug treatment for these conditions
Thyroxine (T4) is the main hormone produced by the thyroid gland,
Free thyroxine (FT4) is the unbound or free proportion of thyroxine in the blood.
Free tri-iodothyonine (FT3) is one of the main proteins produced by the thyroid gland
Anti-TPO Antibody Levels is used to detect Hashitomoto’s thyroiditis and Grave’s disease as well as determining the cause of thyroid problems and assessing potential risk of developing thyroid problems
Anti-TPO Antibody Status evaluates if the level of anti-TPO antibody, if it is negative this is considered normal, if it is positive further investigation may be required
How do I get my results?
Your results will usually be ready in 2-3 days. Melio Health are our labs and diagnostics partner, in your appointment the nurse will register you with them in order for your sample to be tracked, and for the doctors to be able to analyse your results.

About the Advanced Thyroid Function Screen
Thyroid disorders are common and can easily go undetected. Symptoms of a problem with the thyroid function include weight gain, tiredness, low mood and depression, and are often overlooked by patients suffering from disorders.
The Advanced Thyroid Functions Screen measures the levels of three hormones Triiodothyronine (T3), Thyroxine (T4) and Thyroid Stimulating Hormone (TSH), and tests for the Anti-TPI Antibody status. These tests will help our doctors to diagnose a thyroid disorder, such as hypothyroidism and hyperthyroidism, but can also help to detect an autoimmune thyroid disease such as Hashimoto’s thyroiditis and Grave’s disease.
Hypothyroidism, underactive thyroid is the most common thyroid disorder and can be managed with life style and medication.
To monitor the performance of your thyroid over time we suggest you follow this test with an annual Thyroid function test.
Our blood testing services are available for patients aged 16 years and over
