About the 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 Thyroid Screen measures the levels of three hormones Triiodothyronine (T3), Thyroxine (T4) and Thyroid Stimulating Hormone (TSH), this will support a diagnosis and control of hypothyroidism and hyperthyroidism.
Hypothyroidism, underactive thyroid is the most common thyroid disorder and can be managed with life style and medication
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.
Superdrug blood tests are available for patients aged 16 years and older.
