ckd_epi_US: eGFR by CKD-EPI equation (US units)

In transplantr: Audit and Research Functions for Transplantation

Description

A wrapper function for the ckd_epi() vectorised function to calculate estimated glomerular filtration rate using the CKD-EPI equation, using serum creatinine in mg/dl. To allow for serial measurements over time, such as for transplant follow-up data, there is an optional offset = n parameter which increases the age value used in the equation by n years.

Usage

ckd_epi_US(creat, age, sex, ethnicity, offset = 0)

Arguments

creat	numeric vector of serum creatinine in µmol/l (or mg/dl if units = "US")
age	numeric vector of age in years (accepts integers or decimals)
sex	character vector of sex ("F" for female, "M" for male)
ethnicity	character vector of patient ethnicity, one of "black" or "non-black"
offset	non-vectorised optional parameter for offset in years

Value

a numeric vector of eGFR values

Examples

ckd_epi_US(creat = 1.5, age = 64.3, sex = "F", ethnicity = "black")
