eGFR
Cockcroft-Gault estimated GFR with a kidney-function stage.
Glomerular filtration rate estimates how much blood your kidneys filter per minute — the standard way clinicians gauge kidney function, since filtration capacity declines predictably as kidney disease progresses.
The Cockcroft-Gault equation uses serum creatinine along with age, weight, and sex because muscle mass (which produces creatinine) varies systematically across these factors, and the formula corrects for that to avoid skewed estimates.

Estimated GFR: 99 mL/min
Estimated kidney filtration rate is 99 mL/min — classified as "Normal". This is a screening estimate only, not a diagnosis.
