ckdepi_2021_egfr.Rd

[Deprecated]

This function is deprecated; use egfr() with method = "CKDEPI 2021".

Usage

ckdepi_2021_egfr(sexf, age, creat)

Arguments

sexf

boolean value of sex Female: TRUE, Male: FALSE

age

age of subject (years)

creat

creatinine levels of subject (mg/dL)

Value

the eGFR value (mL/min/1.73m2)

Details

The CKD-EPI 2021 creatinine equation (race-free): $$eGFR = 142 \cdot \min(S_{cr}/\kappa, 1)^\alpha \cdot \max(S_{cr}/\kappa, 1)^{-1.2} \cdot 0.9938^A \cdot 1.012^F$$

where:

  • \(S_{cr}\) = serum creatinine (mg/dL)

  • \(\kappa\) = 0.7 (female) or 0.9 (male)

  • \(\alpha\) = -0.241 (female) or -0.302 (male)

  • \(A\) = age (years)

  • \(F\) = 1 (female) or 0 (male)

Examples

e <- egfr(TRUE, FALSE, 24, 1, method = "CKDEPI 2021")
