Private Thyroid Function Blood Test

A healthy thyroid produces hormones that are necessary for cells in the body to function normally - but disorders of the thyroid are very common, and can lead to a wide range of health problems.

Symptoms of Thyroid Disorders

One of the thyroid’s main functions is to produce hormones to help regulate the metabolism, which is the process that turns food into energy. If too many of these hormones are produced (overactive thyroid) then many of the body’s systems start to speed up, causing symptoms such as:

  • nervousness, anxiety and irritability
  • mood swings
  • difficulty sleeping
  • persistent tiredness and weakness
  • sensitivity to heat
  • swelling in your neck from an enlarged thyroid gland (goitre)
  • an irregular and/or unusually fast heart rate
  • twitching or trembling
  • weight loss

On the other hand if too few hormones are produced (underactive thyroid), your systems can slow down, leading to:

  • Tiredness
  • Weight Gain
  • Depression
  • Feeling cold
  • Dry skin & hair
  • Muscle aches

By testing Thyroid Function we can find out whether you may have a thyroid disorder. Most thyroid problems are treated easily with medication, however if they are left untreated they can cause complications which can lead to severe health problems.


We know that waiting for news about your health can be a worrying time, so we aim to have your results fed back to you by the doctor and ready for you to view in your secure online Patient Portal often within 2 working days. The doctor will also advise of any follow-up treatment steps that are recommended.
