What this test is
Cortisol is a hormone made by the adrenal glands that helps regulate energy, blood sugar, blood pressure, and the body's response to stress. Because cortisol normally peaks in the early morning and drops later in the day, testing it twice provides a more complete picture than a single measurement. This test is typically done on blood samples collected in the morning and again in the afternoon.
What it measures
- Morning cortisol — reflects the expected peak level of cortisol after waking
- Afternoon cortisol — shows whether cortisol falls later in the day as expected
- Diurnal variation — the difference between morning and afternoon levels, which reflects the normal daily rhythm
What the test involves
The test involves two standard blood draws, usually from a vein in the arm, one in the morning and one in the afternoon. Each sample is collected into a tube and sent to a laboratory for analysis.
Why it is often ordered
A clinician may order this test when symptoms such as fatigue, weight changes, high blood pressure, or mood shifts suggest a possible problem with cortisol production or regulation. It can also be used to monitor a known adrenal or pituitary condition or to follow up on abnormal results from other tests.
Preparation
Preparation can vary, so follow the collection lab's instructions about timing, fasting, and any medications. Tell the lab about all prescription and over-the-counter drugs, since some can affect cortisol levels.
How results are reported
Results are reported as cortisol values for each collection time, often with a note about whether the pattern is typical or not. Reference ranges differ between laboratories and depend on the assay and collection times, so results should always be interpreted using the range provided by the testing lab.

FAQ
Frequently asked questions
Why are two samples needed instead of one?
Cortisol naturally changes throughout the day, so a single sample can miss an abnormal pattern. Comparing a morning and an afternoon level helps show whether the daily rise and fall is typical. This can give a clinician more useful information than one measurement alone.
Do I need to fast before this test?
Fasting requirements vary by laboratory and by the specific instructions given for your test. Some labs ask you to avoid food for a certain time before the morning draw, while others do not. Always follow the preparation instructions provided by the collection lab.
Can medications affect the results?
Yes, several medications can raise or lower cortisol levels, including some steroids, hormones, and certain other drugs. It is important to tell the lab and your clinician about everything you take. They can advise whether any changes are needed before testing.
How long does it take to get results?
Results are typically available within a few business days after the samples are collected. The exact turnaround time depends on the laboratory performing the analysis. Your ordering clinician will review the results and discuss what they mean for you.
