Overview

The 24-hour urine cortisol test measures total cortisol your body produces and excretes over a full day. Because cortisol rises and falls naturally throughout the day, a single blood draw only captures one point. Collecting urine over 24 hours gives a more complete picture of overall cortisol output.

This test is particularly useful for investigating suspected Cushing's syndrome, where the body produces excess cortisol. It can also help assess other adrenal conditions affecting cortisol production.

Symptoms

Suited to people with suspected Cushing's syndrome, adrenal disorders, unexplained symptoms suggesting cortisol excess, or those whose doctor has requested 24-hour cortisol measurement.

Questions

  • A 24-hour collection captures total cortisol output across the full day. Single blood draws can be affected by timing, stress, and natural fluctuations.
  • Follow the timing instructions exactly. Collect all urine during the 24-hour period. Keep the container refrigerated.
  • Stress, illness, certain medications (especially corticosteroids), kidney disease, and incomplete collection.
  • Typically 28 to 276 nmol per 24 hours, but ranges vary between laboratories.
  • Elevated levels may suggest Cushing's syndrome. Your doctor will likely recommend further specialised testing.
  • Discuss all medications with your doctor. Corticosteroids may need to be paused temporarily.

How to prepare

Obtain the collection container and instructions from your pathology provider before starting. Begin collection after your first morning urination, then collect all urine for exactly 24 hours, finishing with your first morning urination the next day. Keep the container refrigerated throughout. Follow the timing instructions carefully, as missed samples can affect accuracy.

After the test

Discuss results with your doctor. Elevated cortisol may prompt further investigation for Cushing's syndrome. Low results may lead to assessment for adrenal insufficiency. Your doctor may refer you to an endocrinologist for further evaluation.

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 your total 24-hour cortisol excretion compared to reference ranges (typically 28 to 276 nmol per 24 hours). Elevated levels may suggest Cushing's syndrome or other conditions involving cortisol excess. Low levels may point toward adrenal insufficiency. Your doctor will interpret results alongside your symptoms and may recommend further testing.

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"
