70 mL/min/1.73 m²
Sep 18, 2026. Calculated from other results. 4 results in this record.
Judged against the usual range for this sex and age. The lab’s own range wasn’t on the report. The open ring is the result before this one.
eGFR has been lower than the time before at each of the last 4 tests.

eGFR estimates how well the kidneys filter, and it guides the dose of many medicines the kidneys clear. KDIGO notes that in older adults with low muscle mass, creatinine-based eGFR can overestimate kidney function, which can lead to doses that are too high.
The report didn’t print eGFR, so we worked it out from the Creatinine from the same day.
eGFR (mL/min/1.73 m²) = 142 × min(Scr/κ, 1)^α × max(Scr/κ, 1)^−1.200 × 0.9938^age × 1.012 [if female]; Scr = serum creatinine in mg/dL, age in years; κ = 0.7 (female) or 0.9 (male); α = −0.241 (female) or −0.302 (male)
