Cortisol, 24 Hour Urine Test
Item # LC004432
Test assesses 24-hour output of the major adrenal hormone, cortisol
This test is the most accurate way to assess cortisol levels, because it measures the amount of this hormone during a 24-hour period.
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 which can disrupt its normal diurnal control over cortisol. This disruption can lead to symptoms like fatigue, weight gain, insomnia, depression, and anxiety. So if you’re feeling tired and stressed out, check your cortisol level. Cortisol levels rise and fall during the day. The highest levels typically occur at about 6 a.m. to 8 a.m. and the lowest levels at about midnight.
