Hypothyroidism (Underactive Thyroid) Test

The thyroid gland is a small, butterfly-shaped organ in the front of your neck. It produces two hormones, thyroxine and triiodothyronine. When your thyroid isn't functioning properly, it can lead to an underactive thyroid (hypothyroidism), which can cause symptoms like tiredness, weight gain, depression, dry skin, and more.

What do your test results mean and what we recommend you should do next?


Positive Test Result

High Level of Thyroid Stimulating Hormone (TSH)

An abnormally high level of TSH may indicate that you may have an underactive thyroid, also known as hypothyroidism. If your thyroid is not producing enough thyroxine, your pituitary gland releases more TSH to try to get the thyroid gland to produce more thyroxine.

As this test can only detect the presence of high levels of TSH and not what is causing it, it is recommended that you make an appointment with your GP to discuss your results, who will be able to provide guidance and advice on additional investigations that may be required to find out what’s causing it.


Negative Test Result

Normal levels of Thyroid Stimulating Hormone (TSH)

Indicates that your TSH levels are not raised, suggesting you do not have an underactive thyroid.

It is unlikely that any symptoms you may be experiencing are being caused by an underactive thyroid.

You may want to consider repeating the test annually, to check your TSH levels remain within the normal range.
