Cortisol, 24 Hour
Item Catalog Number: LC004432
Cortisol is the major adrenal steroid hormone and is controlled by the pituitary gland and the hypothalamus. The body’s stress response increases Cortisol in order to mobilize energy to manage and resolve the stressor.
Chronic stress can fatigue the adrenal gland, disrupting its normal diurnal control over Cortisol. This disruption results in symptoms like fatigue, weight gain, insomnia, depression and anxiety.
Cortisol levels rise and fall during the day. The highest levels occur at about 6 a.m. to 8 a.m. and the lowest levels at about midnight. Since this test requires a 24-hour urine specimen it integrates cortisol production for an entire day.
Fasting is not required. Take all medications as prescribed.
