Estimated Glomerular Filtration Rate (eGFR)
Females, Age 50-59
The median estimated glomerular filtration rate (eGFR) for US females aged 50-59 in the US population is 98.7 mL/min/1.73 m², with 90% of the population falling between 66.5 and 110.9 mL/min/1.73 m².
NHANES 2017-March 2020 Pre-Pandemic 2017-2020 · Sample size: 1,178 participants · Unit: mL/min/1.73 m²

Data and Methodology
- Dataset
- NHANES 2017-March 2020 Pre-Pandemic ( NHANES 2017–2020 2020 , Primary creatinine, age, sex, and survey-weight source for derived eGFR percentiles; CKD-EPI 2021 2021 , Equation used to derive eGFR from creatinine)
- Survey years
- 2017-2020
- Sample size
- 1,178 participants
- Reference population
- US civilian non-institutionalized females aged 50-59 from NHANES 2017-March 2020, with eGFR derived from serum creatinine using the 2021 CKD-EPI equation. Includes the full population (not restricted to healthy individuals) to reflect the population distribution.
- Exclusion criteria
-
- Missing serum creatinine measurement (LBXSCR) required to derive eGFR
- Missing or zero MEC sample weight (WTMEC)
- Age outside 50-59 range
- Notes
- Percentiles computed using survey-weighted analysis (WTMEC weight, divided by 2 to pool two cycles). eGFR derived from serum creatinine (LBXSCR), age, and sex using the 2021 CKD-EPI creatinine equation: 142 x min(Scr/k, 1)^a x max(Scr/k, 1)^-1.2 x 0.9938^Age x 1.012 if female.
