Renal Function Calculator
Calculate the patient's Glomerular Filtration Rate (GFR) based on their weight (kg) and the creatinine level (mmol/l).
The Renal Function Calculator uses both GFR (Cockcroft-Gault formula) and eGFR (Abbreviated MDRD formula).
To access the Renal Function Calculator, either:
- Press Ctrl+Alt+W. Click the Renal Function tab.
- In the Clinical window, select . The Renal Function Calculator is
displayed.

The Recorded weight and Ideal weight options are disabled when using the eGFR (Abbreviated MDRD formula).

| eGFR (Abbreviated MDRD formula) | Allows you to record and calculate eGFR values using the eGFR (Abbreviated MDRD formula). This option is selected by default. |
| GFR (Cockcroft-Gault formula) | Allows you to record and calculate GFR values using the GFR (Cockcroft-Gault formula). |
