Cortisol Blood Test  1  Test


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.

So if you’re feeling tired and stressed out, check your Cortisol level. We offer this test at a significant discount compared to many commercial laboratories. This test should be checked in the morning … ideally around 8 a.m. We also offer an AM and PM Cortisol collection.

Fasting is not required. Take all medications as prescribed. Do not take your supplements the morning of the test.
