Cortisol blood test
Cortisol is a hormone with one of the body's strongest daily rhythms, peaking in the early morning. Measuring it with a morning blood draw, at its natural peak, gives a clear, comparable reading your doctor can interpret.

Why measure it
A morning reading you can actually interpret
1 draw
Measured at cortisol's natural morning peak, alongside your Advanced blood test.
A clear morning baseline
Taken at cortisol's daily peak, a morning reading gives your doctor a reliable, comparable starting point.
Timing is what makes it meaningful
Cortisol rises and falls through the day, so a morning draw against a reference range is what lets the number be read correctly.
Who is it for?
Who might consider a cortisol test
A cortisol reading can be a useful part of the picture if you have symptoms worth investigating, or want a fuller view of your hormones. It is a starting point, not a diagnosis.
Unexplained fatigue or weight changes
Ongoing tiredness or weight changes without a clear cause can be worth raising with your doctor.
Sleep or energy that feels off
Disrupted sleep or energy dips are common reasons people look at their hormones more closely.
A fuller hormone picture
Anyone who wants cortisol included as part of a broader blood panel.
Guided by your doctor
A symptom or earlier result your doctor wants to look into with a cortisol reading.
Why standard tests miss it
Why a standard panel does not tell you this
A standard blood panel does not include cortisol. And because cortisol rises and falls through the day, a reading only means something when it is taken in the morning, at its natural peak, and read against a reference range. A sample at the wrong time is easy to misread.

What a result gives you
A number your doctor can work with
A morning cortisol result is a starting point, not a diagnosis. Read alongside your symptoms and the rest of your panel, it helps your doctor decide whether anything needs a closer look. A healthy result is a strong morning level, not a low one, and a low reading can matter as much as a high one.
A clear starting point
A morning baseline your doctor can interpret together with your symptoms.
A prompt for the right follow-up
An unusual result can be the trigger for the confirmatory tests that a diagnosis actually needs.
Track it over time
Repeat readings show how your levels change across your check-ups.
Context for your care
Your cortisol adds to the full-body picture your Advanced blood test builds.
