Description

Using KDIGO 2012 Clinical Practice Guideline for the Evaluation and Management of Chronic Kidney Disease Volume 3 | Issue 1 | January 2013

Usage

eGFR(...)
# S3 method for data.frame

  SCr = NULL,
  SCysC = NULL,
  Age = NULL,
  height = NULL,
  BUN = NULL,
  male = NULL,
  black = NULL,
  pediatric = NULL,
  ...
)
# S3 method for units
eGFR(
  SCr = NULL,
  SCysC = NULL,
  Age = NULL,
  height = NULL,
  BUN = NULL,
  male = NULL,
  black = NULL,
  pediatric = NULL,
  ...
)
# S3 method for numeric
eGFR(
  SCr = NULL,
  SCysC = NULL,
  Age = NULL,
  height = NULL,
  BUN = NULL,
  male = NULL,
  black = NULL,
  pediatric = NULL,
  ...
)

Value

Details

Automatic selection of equation to estimation the Glomerular Filtration Rate (eGFR), based on input data

• eGFR_adult_SCr(): 2009 CKD-EPI creatinine equation

• eGFR_adult_SCysC(): 2012 CKD-EPI cystatin C equation

• eGFR_adult_SCr_SCysC(): 2012 CKD-EPI creatinine-cystatin C equation

• eGFR_child_SCr(): Pediatric creatinine-based equation

• eGFR_child_SCr_BUN(): Pediatric creatinine-BUN equation

• eGFR_child_SCysC(): Pediatric cystatin C-based equation
