Overview

Morning cortisol testing at 8am measures your stress hormone at its daily peak. Your adrenal glands should produce maximum cortisol around this time to energize you for the day ahead.

This test primarily screens for adrenal insufficiency (Addison's disease) where the adrenals fail to produce enough cortisol. Low morning cortisol causes severe fatigue, weakness, low blood pressure, and can be life-threatening if untreated, available across Australia.

Elevated morning cortisol may indicate Cushing's syndrome or chronic stress exposure.

Symptoms

Essential for people with unexplained fatigue, suspected adrenal insufficiency, symptoms of Cushing's syndrome, or screening adrenal function.

Questions

  • Cortisol peaks around 8am (within 1 hour of waking). Testing at this time captures your maximum production, making it most useful for detecting deficiency.
  • Typically 140-700 nmol/L (5-25 mcg/dL), though ranges vary by laboratory. Values below 100 nmol/L suggest adrenal insufficiency requiring further testing.
  • Low morning cortisol may indicate adrenal insufficiency (Addison's disease) or pituitary problems. Further testing with ACTH stimulation confirms the diagnosis.
  • Elevated morning cortisol may suggest Cushing's syndrome, chronic stress, or normal variation. Clinical context and additional testing guide interpretation.
  • Acute stress elevates cortisol. Try to remain calm before testing. Chronic stress affects baseline levels and may be clinically relevant.
  • Steroid medications (prednisone, hydrocortisone) affect results and may need to be held. Discuss with your provider—don't stop steroids without guidance.

How to prepare

Critical timing: Blood must be collected at 8:00 AM for accurate results. Fast for 8-12 hours before collection (water allowed). Avoid stress, excessive exercise, and alcohol for 24 hours before testing. Inform healthcare provider of all medications, especially steroids.

After the test

Low cortisol requires investigation for adrenal insufficiency and possible hormone replacement therapy. High cortisol needs evaluation for Cushing's syndrome or stress management. Follow up with endocrinologist for comprehensive adrenal assessment.

Your test results will be available in your private dashboard. If there are any urgent issues, we'll let you know so you can follow up with your health professional.

Understanding results

Results show morning cortisol levels compared to normal ranges (typically 140-700 nmol/L or 5-25 mcg/dL). Low levels may indicate adrenal insufficiency. High levels might suggest Cushing's syndrome or chronic stress. Timing-specific interpretation is crucial.

Simple health checks in my control

I didn't know that private blood tests were an option. Tried this platform as the packages suited what I wanted for a good price. Easy to follow instructions, and super quick results. Platform provides more information than my gp's ever have on the tests and what the results meant. Would like more clinics to be able to test at (specifically Capital Pathology) but there is a decent network. Will continue to use.

"I'm a little biased as I work here! However, I love that The Bloody Good Test tracks my health over time. After turning 40, I wanted to make sure I wasn't going to drop dead from something basic I should have known about earlier. Measuring all my core biomarkers each year gives me peace of mind my health is on the right track"
