Enter the GFR and BSA into the calculator to determine the creatinine clearance. This calculator can also evaluate any of the variables given the others are known.

Gfr To Creatinine Clearance Formula

The following formula is used to calculate the creatinine clearance using GFR (Glomerular Filtration Rate).

CrCl = (GFR * BSA) / 1.73


  • CrCl is the creatinine clearance (mL/min) GFR is the Glomerular Filtration Rate (mL/min/1.73m²) BSA is the Body Surface Area (m²)

To calculate the creatinine clearance, multiply the GFR by the Body Surface Area. Then divide the result by 1.73.

What is a Gfr To Creatinine Clearance?

GFR (Glomerular Filtration Rate) and Creatinine Clearance are both tests used to assess kidney function. GFR measures the rate at which the kidneys filter waste from the blood, while Creatinine Clearance measures the rate at which creatinine, a waste product, is removed from the blood. Both tests are used to diagnose and monitor kidney disease. The results of these tests can help doctors determine how well the kidneys are working and guide treatment decisions.

How to Calculate Gfr To Creatinine Clearance?

The following steps outline how to calculate the GFR to Creatinine Clearance ratio.

  1. First, determine the GFR (Glomerular Filtration Rate) in mL/min/1.73m².
  2. Next, determine the BSA (Body Surface Area) in m².
  3. Next, gather the formula from above = CrCl = (GFR * BSA) / 1.73.
  4. Finally, calculate the Creatinine Clearance (CrCl) in mL/min.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge.

GFR (Glomerular Filtration Rate) = 80 mL/min/1.73m²

BSA (Body Surface Area) = 1.8 m²
