CKD-EPI 2021 creatinine eGFR (race-free) — egfr_ckdepi_cr

Estimates GFR from serum creatinine using the race-free CKD-EPI 2021 creatinine equation (Inker et al., 2021). This is the equation recommended for adults (>= 18 years) by current US guidelines.

Usage

egfr_ckdepi_cr_2021(
  creatinine,
  age,
  sex,
  creatinine_units = "mg/dl",
  label_sex_male = "male",
  label_sex_female = "female"
)

Arguments

creatinine: Numeric vector of serum creatinine.
age: Numeric vector of age in years.
sex: Vector of sex labels (see label_sex_male/label_sex_female).
creatinine_units: Units of creatinine: "mg/dl" (default) or "umol/l".
label_sex_male, label_sex_female: Values in sex that denote male and female records. Defaults to "male"/"female".

Value

Numeric vector of eGFR in mL/min/1.73m^2.
