The GFR Calculator helps you estimate your Glomerular Filtration Rate (eGFR), a key indicator of kidney function. By analyzing factors like serum creatinine levels, age, sex, and race, this tool provides a quick assessment of your kidney health. Understanding your eGFR is crucial for early detection and management of kidney disease. Use our simple online calculator for an immediate estimate.
Formula:
The Estimated Glomerular Filtration Rate (eGFR) is typically calculated using formulas like CKD-EPI, MDRD, or Cockcroft-Gault. These formulas utilize a combination of:
- Serum Creatinine (Scr): A waste product from muscle metabolism, measured in blood.
- Age: In years.
- Sex: Biological sex (male or female).
- Race: (e.g., African American/Other - Note: Modern guidelines increasingly advocate for race-neutral equations, but it's present in some historical formulas like CKD-EPI 2009 for specific adjustments).
The calculation involves complex piecewise functions and coefficients; this calculator uses a common formula (CKD-EPI 2009 creatinine equation) to provide an estimate.
