What's this test for?

This test is ideal if you're experiencing constant fatigue that doesn't improve with rest, feeling overwhelmed by stress, struggling to get out of bed in the morning, or noticing your energy crashes throughout the day. It helps identify hormone imbalances in your stress response system that may be causing these exhausting symptoms. Many people use this test when they feel burned out or suspect their body isn't handling stress well.

How should I prepare for this test?

Fasting: 12 hours
No biotin: 72 hours

You'll need to fast for 12 hours before your blood draw, which means no food or drinks except water during that time. This test must be drawn between 7 AM and 10 AM because cortisol levels are highest in the morning. If you're taking biotin supplements, stop them at least 72 hours before testing. Note that this test is not recommended if you're taking prednisone or prednisolone medications.

What's included in this test?

Dhea, Unconjugated Acth, Plasma Dhea Sulfate Cortisol, am

This comprehensive panel evaluates your stress response system by measuring cortisol (your primary stress hormone), ACTH (which signals cortisol production), DHEA and DHEA-S (hormones that support energy and resilience), and a complete metabolic profile to assess how stress is affecting your overall health. Together, these measurements reveal whether chronic stress has depleted your hormone reserves, why you might feel constantly exhausted, and what's happening in your body when you feel overwhelmed or burned out.

What happens after I get my results?
You'll receive detailed doctor notes in simple language explaining what your stress hormone levels mean for your energy, sleep quality, and ability to handle daily pressures. These notes include personalized recommendations like stress management techniques, sleep hygiene improvements, dietary changes, or supplement suggestions to support your adrenal health. You'll also get the standard lab report and can track your hormone levels over time using our trends feature to see how your interventions are helping you feel better.
When will I get my results?
Your results will be available in approximately 5 business days after your blood sample is collected. If any confirmation testing is needed based on initial findings, the timeline may be extended slightly to ensure accurate results.
Who should consider getting this test?
This test is perfect for anyone experiencing persistent fatigue that rest doesn't fix, feeling wired but tired, difficulty waking up despite adequate sleep, or constant stress that feels unmanageable. It's also helpful for people with afternoon energy crashes, salt or sugar cravings, difficulty concentrating, or those who feel like they're running on empty despite trying to rest and recover.
What symptoms indicate I may need this test?
Common signs include waking up exhausted even after a full night's sleep, needing caffeine or sugar to get through the day, feeling overwhelmed by normal daily tasks, afternoon energy slumps, difficulty recovering from exercise, increased irritability, brain fog, and craving salty foods. You might also notice you get sick more often or take longer to bounce back from illness or stress.
How can I naturally support my adrenal health?
Start by prioritizing consistent sleep schedules with 7-9 hours nightly and managing stress through practices like meditation, deep breathing, or gentle yoga. Focus on balanced meals with adequate protein and healthy fats while reducing caffeine and sugar, which can strain your adrenal system. Include adaptogenic herbs like ashwagandha or rhodiola after consulting a healthcare provider, and make time for activities you enjoy to help your body recover from chronic stress.
What is cortisol and why does it matter?
Cortisol is your body's main stress hormone, released by your adrenal glands to help you respond to challenges and maintain energy throughout the day. It naturally peaks in the morning to help you wake up and gradually decreases by bedtime. When you're under chronic stress, cortisol patterns can become disrupted, leading to fatigue, sleep problems, weight gain around the midsection, weakened immunity, and difficulty managing daily stressors.
What does high cortisol mean?
Elevated cortisol levels typically indicate your body is in a prolonged stress response, which can happen with chronic work stress, emotional pressures, inadequate sleep, or over-exercising. High cortisol can cause anxiety, difficulty sleeping, weight gain especially around your belly, high blood pressure, weakened immune function, and increased blood sugar. It's your body's way of staying in fight-or-flight mode when it should be resting and recovering.
How often should I retest my adrenal hormones?
If you're actively working on stress management, lifestyle changes, or taking supplements to support adrenal health, retesting in 3-6 months helps you see if your interventions are working. If your initial results show significant imbalances and you're working with a healthcare provider on treatment, they may recommend retesting every 2-3 months initially. Once your levels stabilize and you feel better, annual monitoring can help ensure you maintain healthy stress hormone balance.

What this means

Your morning cortisol is slightly below the optimal range, which may explain why you struggle to wake up feeling refreshed and energized. Low morning cortisol can contribute to persistent fatigue, difficulty getting started in the morning, and feeling like you need extra caffeine or stimulants to function.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More complex tests, such as hormone panels, may take up to 10–15 business days due to their complexity.
