Why Diurnal Testing?

Single-point cortisol tests only give you a snapshot. Your cortisol follows a natural rhythm throughout the day — the diurnal pattern. Only a multi-point test can reveal what’s really happening with your stress response.

Morning Spike

Cortisol should peak within 30 minutes of waking. A blunted response often shows up as depression, fatigue, or difficulty losing weight.

Daytime Decline

A healthy curve gradually declines through the day. Elevated afternoon cortisol drives anxiety and belly fat.

Evening Low

Cortisol should reach its lowest at night. Elevated evening levels cause insomnia and that 'wired but tired' feeling.
