Stress is a psychological and physiological response to challenging or threatening situations that triggers measurable changes in your body. It is caused by the release of stress hormones, primarily cortisol, which are produced by the adrenal glands in response to perceived threats or demands. The Cortisol, Total test is the most important test for diagnosis because it directly measures your body's stress hormone levels and reveals how chronic stress is affecting your system.

Stress is caused by your body's natural fight-or-flight response to challenging situations, triggering the release of hormones like cortisol and adrenaline from your adrenal glands. Common triggers include work pressure, financial worries, relationship problems, major life changes, health concerns, and daily hassles that pile up. When you face these challenges, your hypothalamus signals your adrenal glands to flood your body with stress hormones, which increase your heart rate, blood pressure, and energy levels to help you respond to the perceived threat.
The Cortisol, Total test is the most important test for stress because it directly measures the primary stress hormone your body releases during stressful situations. This test reveals whether your cortisol levels are elevated due to chronic stress or if they're abnormally low from adrenal exhaustion. Additional helpful tests include the White Blood Cell Count, which shows how stress is affecting your immune system, and the Reverse T3 test, which detects whether chronic stress is disrupting your thyroid function and energy metabolism. Together, these tests provide a comprehensive picture of how stress is impacting your body at a biochemical level.
You should get tested if you're experiencing persistent fatigue, trouble sleeping, unexplained weight changes, frequent headaches, or feeling constantly overwhelmed despite trying stress management techniques. Testing is especially important if you notice physical symptoms like rapid heartbeat, digestive issues, weakened immunity with frequent colds, or if you're going through a prolonged stressful period such as a demanding job, family crisis, or major life transition. Early detection of abnormal stress hormone levels helps you address the problem before it leads to more serious health complications.

What this means
Your cortisol level is elevated above the optimal range, which suggests your body may be experiencing chronic stress or an overactive stress response. While occasional spikes are normal, sustained high cortisol can contribute to difficulty sleeping, weight gain (especially around your midsection), mood changes, and reduced immune function.
