Adrenal Stress Tests (Stress & Fatigue)

Adrenal stress testing evaluates how your HPA axis (hypothalamus-pituitary-adrenal system) is functioning and whether cortisol patterns could be contributing to fatigue, poor stamina, sleep problems, or stress symptoms. Because these symptoms are nonspecific, testing also checks common look-alikes such as thyroid imbalance, iron deficiency, anemia, depression, sleep disorders, diabetes, liver/kidney issues, medications, and overtraining.

A proactive plan usually starts with 8–9 a.m. serum cortisol (± ACTH) to screen for low cortisol patterns, and late-night ... See more

The 21-Hydroxylase Antibody Test detects autoantibodies that target the adrenal enzyme 21-hydroxylase, often linked to autoimmune Addison’s disease and adrenal insufficiency. A positive result suggests adrenal gland damage caused by immune attack. Doctors use this blood test to confirm suspected Addison’s disease, evaluate unexplained fatigue or low cortisol, and monitor patients at risk for autoimmune polyglandular syndromes or adrenal failure.


The ACTH Test measures adrenocorticotropic hormone in blood to evaluate pituitary and adrenal gland function. Abnormal ACTH levels may indicate Cushing’s syndrome, Addison’s disease, adrenal tumors, or pituitary disorders. Doctors order this test to investigate symptoms such as fatigue, weight changes, weakness, or high blood pressure. Results provide vital insight into endocrine health, cortisol regulation, and adrenal-pituitary balance.

Adrenal glands are quite small but play a crucial role in your life. These glands produce several hormones, including the most notable cortisol hormone, which handles the fight-or-flight response. Early adrenal disease tests help track your hormonal levels and see if they are out of balance. Adrenal disease tests are quite convenient and provide you with the necessary health information you require. 

The Adrenal Glands

The adrenal glands are located on top of the kidneys in the midsection of the body. There are two parts of each gland (medulla and cortex) responsible for producing a different set of hormones. The hormones produced by these glands include: 

  • Aldosterone
  • Cortisol
  • Epinephrine
  • Androgenic steroids
  • DHEA
  • Norepinephrine.
