What's tested?

This blood test gives a good insight into whether your thyroid is working normally or not.

Your thyroid is a small gland in your neck which makes hormones. These hormones regulate your metabolic rate (how quickly your body’s cells use energy) and help maintain your core temperature.

Thyroid problems can lead to tiredness, low mood and weight issues, so it’s essential for your health that it’s working correctly.
A hormone made by your pituitary gland that stimulates your thyroid to make thyroxine.
A hormone made by your thyroid. Essential in many of your body’s functions, including metabolism and growth.

Early signs of a potential thyroid problem can include:

  • weight gain
  • weight loss
  • sweating
  • tremors (shaking)
  • difficulty concentrating
  • hair loss
  • dry skin
  • puffiness of your face, hands or feet

This test includes all the same markers measured in our Thyroid Blood Test, but with the addition of triiodothyronine (free T3), antithyroglobulin and thyroid peroxidase antibodies. These antibodies can help indicate if you have an autoimmune thyroid condition like Hashimoto's disease.

An autoimmune thyroid condition is when your body’s immune system attacks or overstimulates your thyroid. It can cause your thyroid to become overactive or underactive.

Talk to your doctor before taking this test. Being pregnant can have a noticeable impact on your results, so make sure to check in with your GP first.

No, you don't need to fast before this test.
