What does the Cortisol (dried urine) test measure?

Q: What is Cortisol (dried urine)?

Cortisol is the principal glucocorticoid, synthesised in the adrenal cortex under ACTH control. Urinary free cortisol represents the biologically active, unbound fraction filtered by the kidney and integrates cortisol production over the collection period, smoothing episodic secretion.

Q: Why is Cortisol (dried urine) measured?

Elevated urinary cortisol patterns suggest hypercortisolism, chronic stress, or Cushing syndrome (when very high). Low patterns may indicate adrenal insufficiency, HPA axis suppression, or adaptive down-regulation in chronic stress. The HPA-G profile interprets cortisol alongside neurotransmitters to map neuroendocrine resilience.
