Optimising Wellness

The test gives me deeper insight in to whether all of my efforts are actually improving my wellness on the inside. I already track my health but never really knew where to start with at-home testing. I can now see what’s actually working for my health and what’s not.

Frequently asked questions

+

How does the COT test track my inner health over time?

We use your 'lifestyle hormone' cortisol to see what's been happening inside your body over several months. Your cortisol levels accumulate in your hair as it grows - each 1cm of hair growth provides one month's worth of cortisol. This enables you to understand what's been going on inside your body over several months, and not just a snapshot.

What makes Cortigenix's technology unique?

Our unique COT test is the only test in the world developed by independent scientists to assess your cortisol levels over several months. By tracking your cortisol levels over 84 days our test provides up to 42x more insight in to your inner health compared to traditional blood and saliva tests - which can only assess cortisol levels over minutes to hours. Which means that traditional blood and saliva tests do not provide an accurate picture of how your cortisol levels are impacting your long term health.

How do I provide a sample?

Your hair sample is taken from the back of your head. You need a minimum of 1cm of hair in length (roughly half a pencil width in thickness) to provide a sample. Your COT test includes a test tube, a hair tie and a return envelope for you to return your sample to us.
