What This Test Measures
Free Cortisol Rhythm
This test measures free cortisol in saliva across the day to provide insight into your daily cortisol pattern.
The report shows 5 cortisol values, based on samples collected throughout the day. The first 3 morning samples are averaged into one morning value to give a more reliable picture of the cortisol awakening response.
This can help show whether cortisol follows an expected daily pattern or whether levels appear higher or lower at certain parts of the day.

Saliva Sample Collection
The sample is collected using a saliva test at home. You collect saliva in the provided tubes at specific times throughout the day according to the included instructions.
Correct sample timing is important because cortisol naturally changes from morning to evening.
ISO Certified Lab and Analysis
Your samples are analyzed in an ISO certified laboratory using ELISA, Enzyme Linked Immunosorbent Assay, a laboratory method used to measure cortisol levels in saliva.
Biomarkers included
- Cortisol: Cortisol is a steroid hormone produced by the adrenal glands, known as the body's primary stress hormone. It plays a crucial role in regulating metabolism, immune response, and blood pressure, making its levels important for assessing stress response and adrenal function.
How to prepare
**7 days before testing** Avoid hormonal intake unless you specifically want it included in the result. **24 hours before testing** Avoid **alcohol, caffeine, nicotine** and **intense exercise**, as these may affect cortisol levels. **30 minutes before each sample** Do not **brush your teeth, drink, eat, smoke** or **chew gum.** Follow the included instructions carefully for sample timing and collection.
Frequently asked questions
Can caffeine or exercise affect the result?
Yes. Caffeine, nicotine, alcohol and intense exercise may affect cortisol levels, which is why these should be avoided before testing according to the preparation instructions.
Why measure cortisol several times during the day?
Cortisol naturally changes throughout the day. Measuring several time points gives a better view of your daily rhythm than a single cortisol measurement.
Can cortisol be linked to fatigue and sleep problems?
Yes. Cortisol is involved in energy regulation, stress response and sleep wake rhythm. Cortisol patterns may be relevant when symptoms such as fatigue, poor recovery, difficulty waking, energy crashes or trouble winding down are present.
