About this biomarker
eGFR is a calculated estimate based mainly on serum creatinine and demographic inputs. It is used as a standard marker of kidney filtration.
Why it matters
It is one of the main markers used to assess kidney function over time.
What lower levels may suggest
Low eGFR suggests reduced kidney filtration.
What higher levels may suggest
Higher eGFR generally reflects better estimated kidney filtration, though interpretation depends on the lab method and clinical context.
Common tests
Kidney function panel, basic metabolic panel, comprehensive metabolic panel with calculated eGFR
