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

Calculate eGFR from cystatin C using CKD-EPI cystatin C equation; unaffected by muscle mass making it useful in sarcopenic patients

Each component has a specific meaning:

  • Cystatin C — The cystatin c recorded for the scenario being assessed.

Note: Interpret the ckd-epi cystatin c result against the thresholds and context described above.

How to Use

Enter the cystatin C for the scenario you are assessing. Calculate eGFR from cystatin C using CKD-EPI cystatin C equation; unaffected by muscle mass making it useful in sarcopenic patients. Use the ckd-epi cystatin c result to inform your calculation.
