eGFR Calculator

The eGFR Calculator is a tool used to measure kidney function, and is part of the Chronic Kidney Disease requirements. The calculator incorporates two different protocols and you can use either method.

The Sex, Age and any previously recorded Creatinine levels for the patient are displayed (you can also type in the Creatinine result, but this is NOT recorded within the patient record). You can then choose the Equation type – either Abbreviated MDRD or Cockcroft and Gault. If you choose the former type, you will need to specify the Race of the patient.

If you choose the latter Equation type, the eGFR Calculator screen will change to the one below.

The Cockcroft and Gault Equation uses the patient's weight as part of the calculation and this is picked up from previously entered data (you can also type in the weight measurement, but this is not recorded within the patient record).

The eGFR value and recommended CKD Stage displays in the Result box.
