Calculate eGFR by Schwartz cystatin C-based equation (for children only)
Description
Calculate eGFR by Schwartz cystatin C-based equation (for children only)
Usage
egfr.schwartz.cys(cystatin, cystatin_units = "mg/L")
Arguments
cystatin |
Numeric vector. Serum cystatin, could be expressed in "mg/L" or "nanomol/L". Units of measurement should be defined in variable cystatin_units (if not defined explicitly by user, the default value is "mg/L"). |
cystatin_units |
Character string. Units in which serum cystatin is expressed. Could be one of the following: "mg/L" or "nanomol/L" |
Details
Calculate estimated glomerular filtration rate (eGFR) by Schwartz cystatin C-based equation.
