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 using combined creatinine-cystatin C CKD-EPI equation. More accurate than either single biomarker for GFR estimation

Each component has a specific meaning:

  • Combined creatinine-cystatin C CKD-EPI equation — The combined creatinine-cystatin c ckd-epi equation recorded for the scenario being assessed.

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

How to Use

Enter the combined creatinine-cystatin C CKD-EPI equation for the scenario you are assessing. Calculate eGFR using combined creatinine-cystatin C CKD-EPI equation. More accurate than either single biomarker for GFR estimation. Use the ckd-epi combined result to inform your calculation.
