Cortisol Level

Cortisol is a stress hormone from the adrenal glands that follows a daily rhythm — highest in the morning, lowest at night. The same number means something different depending on when it was drawn.

What it means

Within the normal range (5–23, morning reading).

Formula

Result = band(Cortisol (μg/dL))

This calculator assumes a morning (roughly 8am) blood draw. A reading taken at another time of day does not fit these bands.

Frequently asked questions

QHow is Cortisol Level calculated?

Result = band(Cortisol (μg/dL)) — Cortisol is a stress hormone from the adrenal glands that follows a daily rhythm — highest in the morning, lowest at night. The same number means something different depending on when it was drawn.

QCan you walk through an example?

With Cortisol (μg/dL) 12μg/dL, the answer is Result 1.

QWhat do I need to enter?

Enter Cortisol (μg/dL). The result recalculates as you type, and an empty box counts as zero.

QHow much does the answer move if I change a number?

Changing only Cortisol (μg/dL) (μg/dL) moves the answer to Cortisol (μg/dL) (μg/dL) 6 → Result 1 and Cortisol (μg/dL) (μg/dL) 24 → Result 2. The table below lays out five steps.

QHow are the numbers rounded?

Money is shown to the nearest whole unit, percentages to one decimal place and everything else to two. What you see is rounded; the calculation itself carries the unrounded value forward.

QAnything to watch out for?

This calculator assumes a morning (roughly 8am) blood draw. A reading taken at another time of day does not fit these bands.
