What Is a Metabolic Panel With EGFR?

A metabolic panel with eGFR is a blood test to measure blood sugar, fluid and electrolyte levels, and kidney and liver function, states WebMD. The National Institutes of Health explains that eGFR stands for Estimated Glomerular Filtration Rate, a test used to measure kidney function.

A doctor may order a basic or comprehensive metabolic panel. The difference between basic and comprehensive tests is that a comprehensive metabolic panel tests for liver enzymes and a basic metabolic panel does not, according to WebMD. A doctor may request a metabolic panel with eGFR as part of a regular health examination, or in response to specific conditions or symptoms.
