WHEN TO TAKE THE TEST?
You can provide the sample for the thyroid check at any time, but we don’t recommend checking your thyroid levels during illness as this may give an inaccurate result.
Our thyroid check is for anyone wanting to check if their symptoms – such as a sudden change in weight, mood changes, difficulty sleeping or muscle weakness – could be due to a thyroid issue. It is also useful for monitoring an existing thyroid condition.
3 Biomarkers
Thyroid Stimulating Hormone (TSH)
Thyroid-stimulating hormone (TSH) regulates thyroid function by stimulating the production of thyroid hormones T3 and T4, which control metabolism and energy production. Women are more likely to develop thyroid disorders than men. Abnormal thyroid levels impact weight, energy levels, mood, menstrual cycle and can cause erectile dysfunction in men.
Thyroxine (T4, free direct)
A thyroxine (T4) test is used to check that the thyroid is performing properly. An overactive thyroid can cause too much thyroxine to be released whilst an underactive thyroid can lead to too little. Abnormal levels can impact weight, energy, and mood. Free T4 measures the free or unbound levels of T4.
Triiodothyronine (T3, free)
Triiodothyronine (T3) is the active form of thyroxine (T4). High T3 levels may indicate hyperthyroidism, with symptoms such as fatigue, weight loss, irritability, and increased heart rate. Low T3 levels can suggest hypothyroidism, causing fatigue, weight gain, and muscle stiffness. Free T3 measures the free or unbound levels of T3.

"A thyroid function blood test evaluates the health of your thyroid gland. It measures levels of thyroid hormones (T3 and T4) and thyroid-stimulating hormone (TSH). Abnormal results can reveal hyperthyroidism (overactive thyroid) or hypothyroidism (underactive thyroid), this test is particularly useful for looking at causes of fatigue, mood changes and weight fluctuations.

Can I have someone take my blood for me?
Yes. We offer two options if you do not want to do our finger prick test. The first is a home appointment where a nurse comes to your home to take a blood sample. The second is to visit a Phlebotomy clinic near you that offers a blood sample service.
A blood sample will be taken from your vein and we will provide you with everything you need to give to the nurse to allow them to take the sample.
The nurse will give you the blood sample to return to us using the pre-paid envelope provided.
