Stress, Sleep & Neurotransmitter Testing
Adrenal Cortisol Stress Test
Also known as: Diurnal (4-point) salivary cortisol
Saliva samples across one day that map your stress hormone curve.
Cortisol should be highest shortly after waking and fall steadily until bedtime. When that curve flattens, flips, or spikes at the wrong time, you can feel exhausted in the morning and wired at night. Four saliva samples collected over one day show exactly where your rhythm stands.

How we interpret it
We read every panel through a functional lens — optimal reference ranges, ratios, and cross-panel patterns. Results become part of your written Root Cause Report and your personalized 12-week protocol.
We compare your cortisol curve with your HTMA sodium and potassium levels to see how your adrenals are coping, then use minerals, meal timing, and daily rhythm to help bring the curve back toward balance.
