Cortisol Urine Test
|See Also||Lab Tests|
Cortisol is a glucocorticoid released from the adrenal cortex. This hormone affects the metabolism of carbohydrates, proteins, and fats. It also significantly affects glucose serum levels. Cortisol can increase glucose by stimulating gluconeogenesis from glucose stores as well as inhibit the effect of insulin, thereby inhibiting glucose transport into the cells. ,
- This test is performed in patients with suspected hypo- or hyperfunction of the adrenal gland.
- Elevated urine levels indicate elevated serum cortisol levels.
- Factors which can cause increased levels:
- pregnancy, physical and emotional stress
- Drugs: oral contraceptives, danazol, hydrocortisone, and spironolactone (Aldactone)
- Factors which can cause decreased levels:
- none noted
- Drugs: dexamethasone, ethacrynic acid, ketoconazole, and thiazides
High levels indicate:
Low levels indicate:
