A salivary cortisol test is a diagnostic procedure that measures the level of cortisol present in your saliva. This simple, non-invasive test provides valuable insights into your body's stress response and overall adrenal function.
Understanding Cortisol and Its Role
Cortisol is a crucial hormone produced by the adrenal glands, which are located on top of each kidney. This hormone plays a vital role in several bodily functions, including:
- Energy Metabolism: Cortisol helps the body utilize glucose (sugar) and fat for energy.
- Stress Management: It is essential for managing stress responses.
- Other functions: Cortisol has a multitude of other roles in the body.

- Non-invasive: The procedure is simple and non-invasive, usually involving spitting into a collection tube.
- Convenient: It can be performed at home and sent to a lab for analysis.
- Multiple measurements: Multiple measurements can be taken throughout the day to assess cortisol fluctuations.
