CKiD U25 creatinine eGFR — egfr_ckid_u25

Estimates GFR in children and young adults (ages 1-25) using the CKiD U25 creatinine equation (Pierce et al., 2021). This is the first-choice paediatric equation.

Usage

egfr_ckid_u25_cr(
  creatinine,
  age,
  sex,
  height,
  creatinine_units = "mg/dl",
  height_units = "cm",
  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).
height: Numeric vector of height.
creatinine_units: Units of creatinine: "mg/dl" (default) or "umol/l".
height_units: Units of height: "cm" (default) or "m".
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.

Validity

Developed for ages 1-25 years; the reference calculator published with the equation is restricted to that range. Values outside it are extrapolations.
