How is this cortisol weight management different to other cortisol tests?

This stress hormone cortisol test measures your long-term average cortisol levels over the past 3 months. This test is different to ‘acute’ blood, saliva and urine tests which only measure your short-term cortisol levels over minutes to hours.

Here are some important things you should know about testing cortisol for stress:

Long-term measurement: Testing cortisol levels for stress is difficult using blood, saliva and urine. These tests only provide a ‘snapshot’ of cortisol levels at the time of testing or over a 24-hour period. Whereas our weight management cortisol test measures cortisol levels in hair which provides a measure of cortisol levels over several months.

Cortisol levels change minute-by-minute and from day-to-day: Your cortisol levels can change minute-by-minute from day-to-day. This means that a traditional weight management cortisol test using blood, saliva and urine can provide different results on different days leading to misdiagnosis and missed diagnosis. This is why our test measures your average cortisol levels over 3-months.

Cortisol levels also change from day-to-day which means that your results can be different on different days which can lead to misdiagnosis and missed diagnosis. This is why Cortigenix’s Cortisol Over Time (COT) test measures your average cortisol levels over 3-months.

More accurate than blood, saliva and urine cortisol tests: Cortisol levels in hair have been shown to be the most accurate way to measure cortisol. Cortisol levels in blood, saliva and urine can be influenced by a variety of factors, including acute stress, physical activity, and medications, whereas cortisol levels in hair reflect a more stable measure of long-term cortisol exposure.

Less invasive: A weight management cortisol test that uses blood can be uncomfortable or even painful for some people. Collecting a hair sample is less invasive and completely painless.

What is cortisol?

Cortisol is a glucocorticoid hormone often called the ‘stress hormone’ because of it’s role in helping the body respond to stress.

Cortisol has many vital roles and regulates a wide range of processes throughout the body. Cortisol regulates the immune system, reproductive functions, metabolism, helps to maintain brain health, and regulates blood pressure.

Every cell and system in the body has receptors for cortisol so the effects of cortisol on health are far reaching depending on the cells, tissues and systems cortisol is acting upon.

+

Is your test available worldwide?

Yes. We ship globally and you can order our cortisol test from 170 countries worldwide.

+

What is the science behind Cortigenix’s cortisol test?

Our cortisol test has been independently validated based on data from thousands of research participants. Our research partners include the University of Nottingham, University of Auckland and Kings College London.

Why is it necessary to measure cortisol over 3-months?

Measuring cortisol levels over 3-months is necessary because cortisol levels fluctuate and can change minute-by-minute and day-by-day. If you have had a ‘low’ or ‘high’ cortisol level in the past it is possible your result may be due to a temporary spike in cortisol levels due to acute stress, the time of day you took your samples or simply down to a ‘bad day’.

To get an accurate measurement of chronic stress and adrenal function we have to measure cortisol function over time (i.e., several months).

This is similar to a HbA1c test that measures your average blood sugar levels over the past 3 months and is commonly used to diagnose and manage diabetes.

Why does this test use hair to test cortisol levels?

The science is clear that hair is the most accurate way to measure cortisol levels over time. Blood, saliva and urine cortisol tests only provide a short-term snapshot of cortisol over minutes to hours.

This is a problem because cortisol levels fluctuate and can change minute-by-minute and day-by-day. Therefore ‘low’ or ‘high’ cortisol level may be due to a temporary change or spike in cortisol levels due to acute stress, the time of day you took your samples or simply down to a ‘bad day’.

By using hair we are able to measure your average cortisol levels over 3-months without the need for repeated samples which are more time-consuming and more expensive.

How much hair do I need to provide?

You will need to provide a small hair sample from your head using scissors. The minimum amount of hair we need is 1cm in length and around 8-10 strands of hair in thickness (2-3 mm).

+

Where should I take my hair sample from?

We recommend taking a sample from the back of your head near to the ‘cranial bone’ (this is the bump you can feel at the back of your head).

+

Will any hair bleaching and hair treatments impact my results?

No, Hair samples are stripped of any contaminants before being analysed.

Your results will be delivered through your personalised dashboard within 10 working days. We will notify you via email when your results are ready.
