Lab Tests for Adrenal Fatigue
Adrenal fatigue describes a collection of symptoms — persistent tiredness, difficulty waking, salt cravings, and reliance on caffeine — thought to result from chronic stress depleting your adrenal glands. While not a formal medical diagnosis, the symptoms are real and often driven by measurable hormonal and nutritional imbalances. Lab testing helps identify cortisol irregularities, DHEA-S depletion, thyroid dysfunction, and vitamin deficiencies that can cause these symptoms. With JustLabs, you can order a targeted adrenal health panel online at transparent prices, no doctor visit required.
Recommended Tests
Understanding Your Results
| Test | Normal Range | Low Means | High Means |
|---|---|---|---|
| Cortisol (AM) | 6.2–19.4 mcg/dL | Low cortisol output — adrenal insufficiency | Chronic stress response, Cushing's consideration |
| DHEA-S | Varies by age/sex | Adrenal reserve may be depleted | Typically normal or benign |
| TSH | 0.4–4.0 mIU/L | Rule out hyperthyroidism | Hypothyroidism mimics adrenal fatigue symptoms |
| Vitamin D | 30–100 ng/mL | Deficiency worsens fatigue | Unlikely unless supplementing heavily |
| Ferritin | 12–300 ng/mL | Low iron stores — common fatigue cause | Inflammation or iron overload |
