Cortisol follows a natural diurnal rhythm — highest in the early morning and lowest in the late evening. A PM cortisol test measures levels in the afternoon or evening to evaluate whether this pattern is intact. Abnormally high PM cortisol can indicate Cushing's syndrome, chronic stress, or HPA axis dysregulation. When paired with an AM cortisol test, the PM result provides a more complete picture of adrenal function. This test is commonly ordered for patients with symptoms of adrenal dysfunction, including fatigue, weight gain, insomnia, anxiety, and difficulty recovering from stress.
