Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Assess adrenal insufficiency likelihood from random cortisol: <3 mcg/dL confirms, >18 mcg/dL excludes; 3-18 mcg/dL requires stimulation testing

Each component has a specific meaning:

  • Random cortisol: <3 mcg/dL confirms — The random cortisol: <3 mcg/dl confirms recorded for the scenario being assessed.
  • >18 mcg/dL excludes; 3-18 mcg/dL requires stimulation testing — The >18 mcg/dl excludes; 3-18 mcg/dl requires stimulation testing recorded for the scenario being assessed.

Note: Interpret the adrenal crisis result against the thresholds and context described above.

How to Use

Enter the random cortisol: <3 mcg/dL confirms, >18 mcg/dL excludes; 3-18 mcg/dL requires stimulation testing for the scenario you are assessing. Assess adrenal insufficiency likelihood from random cortisol: <3 mcg/dL confirms, >18 mcg/dL excludes; 3-18 mcg/dL requires stimulation testing. Use the adrenal crisis result to inform your calculation.
