Diurnal Cortisol & CAR Test
GetTested’s Diurnal Cortisol & CAR Test measures cortisol at six time points throughout the day, along with DHEA-S, to provide a detailed view of how cortisol levels change from morning to night.
This test is designed to assess the full daily cortisol curve, including the cortisol awakening response (CAR), and may be relevant when exploring factors such as fatigue, stress, sleep patterns, or daily energy variation.
Collected at home using saliva, the samples are analyzed in a CLIA-certified laboratory, with results delivered digitally.
Approved for New York residents.

About Diurnal Cortisol & CAR Test
What your cortisol rhythm can indicate
Cortisol follows a daily rhythm, typically rising shortly after waking and gradually declining throughout the day.
By measuring cortisol at multiple time points, this test provides a detailed view of how levels change from morning to night, rather than relying on a single measurement.
A key component is the cortisol awakening response (CAR), the natural increase in cortisol that occurs within the first hour after waking. Measuring cortisol immediately upon waking and again at 30 and 60 minutes helps illustrate how the body initiates the day.
DHEA-S is also measured to provide additional context to cortisol patterns, as it is another hormone produced by the adrenal glands.

How It Works
You collect saliva samples at home at six time points during the same day: upon waking, 30 minutes after waking, 60 minutes after waking, around midday, in the evening, and at night.
The samples are then sent to a CLIA-certified laboratory for analysis, and your results are delivered digitally once testing is complete.
Saliva Collection
The test uses saliva samples collected at home.
This non-invasive method allows for repeated measurements throughout the day, making it possible to assess how cortisol levels change over time. Samples are collected according to the schedule provided in your kit and sent to the laboratory for analysis.
