About this test
About this test
Cortisol stimulates the release of epinephrine and norepinephrine causing the "fight or flight" physical response in humans.
Symptoms of Unbalanced Cortisol may include:
Bone loss and weakness
High blood pressure
Weight gain or weight loss
Low blood sugar
Diarrhea, nausea or vomiting
When to test
The cortisol test checks your cortisol production levels indicating if the levels in your blood are too high or too low. If your cortisol levels are too high, you may develop Cushing syndrome (too much cortisol) or Addison's disease (too little cortisol.)
You should take the test if:
You constantly feel run down
You are body-building competitively
You are presenting with symptoms of Cushing syndrome
You have Cushing syndrome
You are presenting with symptoms of Addison's disease
You have Addison's disease
You take or have been taking testosterone
The sample must be collected between 8am and 10am on a Monday, Tuesday, Wednesday or Thursday and returned on the same day.
Engaging in vigorous physical activity the day before taking this test can lead to an increase in your cortisol levels.
Cortisol, known as the stress hormone, is released in response to stress or low blood glucose. Cortisol levels vary throughout the day and impact blood sugar levels, your metabolism, acts as an anti-inflammatory, and helps regulate blood pressure.
