How can a thyroid blood test help you?

This test checks your thyroid function and helps you understand if your symptoms might be due to a thyroid disorder, like an overactive or underactive thyroid. It also checks to see if you’re getting enough of the nutrients needed for a healthy thyroid or whether your symptoms may be due to key vitamins and minerals deficiencies.

An underactive thyroid (hypothyroidism) and overactive thyroid (hyperthyroidism) could explain :

  • weight loss or weight gain
  • shaking and tremors
  • increased irritability, anxiety, or depression
  • fatigue and lack of energy
  • muscle aches, cramps, or weakness
  • low sex drive (libido)
  • irregular or heavy periods

Once diagnosed, your thyroid function needs to be monitored to ensure your thyroid hormone levels are optimal. With a GP report and advice on how to maintain or improve your results, we help you understand how to support your thyroid function.

We recommend doing a thyroid blood test every 3 months if you have an underactive or overactive thyroid.
