What is the GFR Calculator?
The GFR Calculator estimates your glomerular filtration rate, a key indicator of kidney function. It uses the CKD-EPI 2021 and MDRD equations based on serum creatinine, age, and gender.
How to Use
- Select your creatinine units (mg/dL or μmol/L).
- Enter your age, gender, and serum creatinine level.
- Click Calculate to see eGFR values and the corresponding CKD stage.
FAQ
What is a normal eGFR?
A normal eGFR is 90 mL/min/1.73m² or higher. Values below 60 may indicate reduced kidney function.
What are the CKD stages?
G1: �?0, G2: 60-89, G3a: 45-59, G3b: 30-44, G4: 15-29, G5: <15 mL/min/1.73m².
Should I use CKD-EPI or MDRD?
CKD-EPI 2021 is generally preferred for eGFR > 60, while MDRD is widely used in clinical settings. Both are provided for reference.
