Cortisol Blood Test

People experiencing persistent fatigue, difficulty waking, low mood, disrupted sleep, or sustained high-stress lifestyles who want to understand whether their cortisol rhythm is a contributing factor.

Your serum cortisol level interpreted against the normal diurnal morning range. Elevated cortisol points to chronic stress or adrenal overactivation; suppressed cortisol may indicate HPA axis dysregulation or adrenal insufficiency.

Cortisol sits at the intersection of stress, sleep, metabolism, and immune function. A morning measurement is the most clinically practical starting point — and often the first objective signal that something is worth investigating further.
