Simple at home blood test
What This Test Measures
This test measures two key adrenal hormones:
Cortisol
A hormone released in response to stress, involved in regulating energy, metabolism, immune function, and daily rhythm.
DHEA-S
A hormone associated with recovery, resilience, and hormonal balance, and a precursor to sex hormones such as estrogen and testosterone.
Together, these markers provide insight into how the body manages stress and long-term balance.
About Adrenal Function and Stress
The adrenal glands play a central role in how the body responds to stress, energy demands, and hormonal balance.
Cortisol regulates the body’s immediate stress response and supports functions such as energy, metabolism, and daily rhythm, while DHEA-S is involved in recovery, resilience, and hormonal balance.
Imbalances in these hormones may be associated with fatigue, low stress tolerance, mood changes, or disrupted sleep.
Measuring both markers provides insight into how your body manages stress and recovery over time, and may help explain why you feel out of balance even when other results appear normal.
How It Works
1. Order Your Kit
Purchase your test online
2. Collect Your Sample
Take a finger prick blood sample at home
3. Send It Back
Mail your sample to the laboratory
4. Receive Your Results
Access your results within 10–15 days
Sample Collection
The sample is collected using a dried blood spot (DBS) method through a simple finger-prick test at home. You collect a small amount of blood on a sample card, which is then sent to the laboratory for analysis.
This method is practical, minimally invasive, and well-suited for reliable home testing.
ISO-Certified Lab and Analysis
Your sample is analyzed in an ISO-certified laboratory using Electrochemiluminescence (ECL), a highly sensitive and widely used method for hormone measurement.
Biomarkers included
- DHEA-S: DHEA-S is a hormone produced mainly by the adrenal glands and serves as a precursor to sex hormones, including androgens and estrogens. Compared with DHEA, DHEA-S is more stable in the bloodstream and is therefore commonly measured to evaluate adrenal androgen production. Levels typically peak in early adulthood and gradually decline with age. Elevated DHEA-S may be seen in conditions associated w
- 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
Take the test in the morning between 07:00 and 08:00, when cortisol levels are naturally at their highest. Avoid intense physical activity before sampling for more consistent results.
Frequently asked questions
What is the difference between this test and a saliva-based adrenal test?
This blood test measures baseline levels of cortisol and DHEA-S, providing an overview of adrenal function. Saliva tests measure cortisol at multiple points during the day and are used to assess daily variation.
Why measure both cortisol and DHEA-S?
Cortisol reflects the body’s stress response, while DHEA-S is associated with recovery and resilience. Measuring both provides a more complete picture of adrenal function.
Can this test diagnose adrenal disorders?
No, this test does not diagnose medical conditions. It provides additional information that may be used alongside other clinical assessments.
Customer reviews
4.7/5 (3)
- 5/5 — Really glad I tested both cortisol and DHEA-S together for a full picture.
- 5/5 — Fast delivery and the finger prick was easy enough to do at home.
- 4/5 — Clear results that helped me understand my morning fatigue better. Wish the lab turnaround was a few days faster though.
