Calculate Estimated Glomerular Filtration Rate

Usage

egfr(
  sexf,
  raceb,
  age,
  creat,
  ...,
  cystc = NULL,
  height = NULL,
  method = "CKDEPI 2021"
)

Arguments

sexf

a boolean representing if the patient is female.

raceb

a boolean representing if the patient is black.

age

the age of a patient in years.

creat

the serum creatinine levels in mg/dL.

...

reserved; must be empty. Arguments after creat must be named.

cystc

the cystatin C levels in mg/L - required for the "CKDEPI 2021 cystatin" method.

height

the height of a patient in cm - required for the "Schwartz" method.

method

equation to use, one of: egfr(method = "CKDEPI 2009"), egfr(method = "MDRD"), egfr(method = "CKDEPI 2021"), egfr(method = "CKDEPI 2021 cystatin"), egfr(method = "Schwartz").

Value

the eGFR calculated based on method.
