What can I learn from a cortisol test?

Your cortisol levels naturally fluctuate throughout the day — they should be highest in the morning and gradually drop so they reach their lowest point at night. With a saliva test, you can collect multiple samples over the course of one day to see if you follow the normal daily pattern.

This test can help you learn if things like sleep problems, low energy levels, low mood, getting sick often, and weight gain might be because your cortisol levels are too high.

Based on your results, you’ll get personalised advice from a GP on how to improve your levels.
