QuestionChoice
This option does not contain the correct combination of parameters for the MDRD equation. Another parameter used in the calculation of the glomerular filtration rate is "inulin clearance" which is considered the gold standard in estimating the GFR. It depends on measuring the clearance of inulin from the bloodstream which is 100% excreted via the glomeruli and, although gold standard, it has its own practical challenges as it requires an inulin infusion and urine collection for hours.

d
Sex, serum potassium, inulin, age
QuestionChoice
This option has substituted "serum creatinine" for "serum potassium" so therefore does not contain the correct combination of parameters for the MDRD equation.

e
Age, sex, serum potassium and race
QuestionChoice
This option has substituted "serum creatinine" for "weight" so therefore does not contain the correct combination of parameters for the MDRD equation. Another equation used in the calculation of the glomerular filtration rate is the Cockcroft-Gualt equation which uses age, weight, sex, creatinine and race. However, its use is inaccurate in pregnancy, amputation, extremes of weight and low/high protein diets.

b
Weight, age, race and sex
QuestionChoice
The Modification of Diet in Renal Disease Study Group (MDRD) equation is a method used for estimating kidney function in patients. It involves four parameters - age, sex, serum creatinine and race. It is important to note that it will be inaccurate in pregnancy, amputation, extremes of weight and low/high protein diets.

The GP decides to calculate the eGFR of a patient with known chronic kidney disease (CKD). He uses the MDRD equation.

Which parameters are included in this equation?
