Biomarkers included – Cortisol Test (Small)
- 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 – Cortisol Test (Small)
Avoid food, drink, and tooth brushing for 30 minutes before each collection. Rinse mouth 10 minutes before sampling. Ship samples early in the week.
Frequently asked questions – Cortisol Test (Small)
Why do I need to test four times a day instead of once?
A single test only shows your level at one moment. Because cortisol fluctuates throughout the day, a 4-point test is required to see your salivary cortisol rhythm and identify if you are spiking or crashing at inappropriate times.
What is the difference between saliva and blood cortisol tests?
Saliva measures 'free' cortisol, which is the active form of the hormone. Blood tests measure 'total' cortisol, much of which is bound to proteins and inactive. Saliva is often considered more representative of the stress levels affecting your tissues and is essential for measuring the diurnal cortisol slope.
How do I prepare for the test?
Wait at least 30 minutes after eating, drinking, or brushing your teeth before collecting a sample. Rinse your mouth with water 10 minutes prior to collection to ensure purity and avoid sample contamination. Certain medications and supplements, including corticosteroids, may affect cortisol levels and influence test results.
How long do the samples remain stable in the mail?
Samples are stable at room temperature for several days. We recommend shipping your adrenal fatigue test kit back on a Monday or Tuesday using the provided stabilization tubes to maintain sample integrity and avoid weekend transit delays.
