Cortisol, P.M. details
What Cortisol, P.M. shows
Cortisol is the main stress hormone made by the adrenal glands. It normally peaks early in the morning and falls through the afternoon and evening. Measuring it later in the day helps check whether this natural decline is happening. A level that stays high in the afternoon or evening can point to a disrupted rhythm, which can be seen with stress, illness, shift work or poor sleep, and sometimes with cortisol excess. A single result does not confirm a condition, and it is usually compared with a morning cortisol and interpreted alongside symptoms, medications and the exact collection time.
