Frequently asked questions
What is the formula to convert cortisol?
nmol/L = µg/dL × 27.59. To go the other way, divide instead of multiply.
Which unit does my country use for cortisol?
The US typically reports µg/dL; most of Europe, Russia and Israel use nmol/L. Your lab prints its unit next to the value.
Does converting change what my result means?
No - it's the same value in a different unit. Always compare it to your own lab's reference range and discuss with your doctor.
