Calculate eGFR by all creatinine-based equations for adults

Usage

egfr.all_adults.cr(
  creatinine,
  age,
  sex,
  ethnicity = NA,
  creatinine_units = "micromol/l",
  label_sex_male = c("Male", 1),
  label_sex_female = c("Female", 0),
  label_african = c("Afroamerican"),
  max_age = 100
)

Arguments

creatinine

Numeric vector. Serum creatinine, could be expressed in "micromol/L", "mmol/L" or "mg/dL". Units of measurement should be defined in variable creatinine_units (if not defined explicitly by user, the default value is "micromol/L").

age

Numeric vector. Age, in years.

sex

Vector. The value of variable refers to the parameters label_sex_male and label_sex_female.

ethnicity

Vector. Ethnicity. If no ethnicity will be defined, the calculation will use coefficients for Caucasian subjects. Specify ethnicity labels in the function parameter label_african.

creatinine_units

Character string. Units in which serum creatinine is expressed. Could be one of the following: "micromol/L", "mmol/L" or "mg/dL".

label_sex_male

List. Label(s) for definition(s) of male sex.

label_sex_female

List. Label(s) for definition(s) of female sex.

label_african

List. Label(s) for African ethnicity. Required only by race-specific equations.

max_age

Numeric. Maximal age suitable for the equation application, in years. By default is 100 years, but change this value in case you would like to apply equation to older persons.

Value

numeric eGFR expressed in ml/min/1.73m2.

Details
