Description
Cortisol blood testing helps diagnose adrenal disorders like Cushing’s syndrome or Addison’s disease; in China, the test typically costs ¥15–¥45 and ChinaMedicalHub can assist with hospital booking and interpreter support.
Main Uses
Cortisol testing is primarily used to diagnose Cushing's syndrome and Addison's disease, evaluate the function of the adrenal and pituitary glands, and monitor the effectiveness of treatments for conditions affecting these glands. It is also used to assess the body's response to stress and to diagnose adrenal insufficiency.
Normal Range
The normal range for cortisol levels can vary depending on the time of day and the specific laboratory. Typically, in the morning (around 8 AM), the normal range is approximately 6-23 mcg/dL, while in the evening (around 4 PM), it drops to about 3-16 mcg/dL.
Low Values - Possible Causes
Adrenal insufficiency, Addison's disease, hypopituitarism, severe stress or illness, and certain medications like ketoconazole
