Cortisol Test

Check your cortisol levels with our home cortisol blood testing. Simply order your kit and take a sample with the easy to use finger prick device. Send your sample back to us and it will be analysed in a UK lab before the detailed results are made available to you on a secure and insightful online dashboard.

Cortisol is a steroid hormone produced by the adrenal gland and released in response to stress. Our lab analysed finger prick blood test enables you to check your levels of cortisol quickly and easily.

Your cortisol levels will rise if your body is placed under stress. If your body is put under prolonged stress cortisol may be unable to respond, which can lead to a condition known as adrenal burnout.

Levels naturally fluctuate throughout the day, so the test should be taken in the morning before 10am.

Why take a cortisol test?

  • To check your adrenal gland function
  • To check whether your body might be under too much stress
  • To check whether you may be over training

Benefits of cortisol testing

Our cortisol blood test kit is a finger prick test you take at home. You then simply send it back to us and you’ll have your cortisol level result on an easy-to-understand digital dashboard within days.

By checking your levels, you can begin to understand whether your body might be suffering from too much stress. This, in turn, can help you to make the lifestyle changes to lower your cortisol levels and therefore minimise any other health risks associated with physical or emotional stress.

Similarly, low levels of cortisol might indicate a problem with adrenal gland function, which you can then investigate further with the help of health professionals.

I suffer from a hereditary condition which causes my body to store too much iron.  My biggest issue before using Forth was getting an appointment with my GP.  Now using Forth I can track my iron levels quickly and easily and take action before levels start to affect my health.
