egfr_mdrd: Estimated GFR Using the MDRD Formula

In rpkyle/cscmisc: Miscellaneous Data Manipulation and Simulation Tools

Description

Computes estimated glomerular filtration rate (GFR) using the Modification of Diet in Renal Disease (MDRD) formula.

Usage

egfr_mdrd(..., scr.mg.dL, age.yr, is.female, is.black, bun.mg.dL=NULL, albumin.g.dL=NULL, scr.umol.L, scr.conversion.factor = 88.4)

Arguments

...	Ignored. This forces all parameters to be named, which is safer.
scr.mg.dL	Numeric. Serum creatinine in mg/dL.
age.yr	Numeric. Age in years.
is.female	Logical. TRUE for females, FALSE for males.
is.black	Logical. TRUE if race is 'black', FALSE otherwise.
bun.mg.dL	Numeric. Blood urea nitrogen (BUN) concentrations in mg/dL (optional).
albumin.g.dL	Numeric. Albumin concentration in g/dL (optional).
scr.umol.L	Numeric. Alternative specification of serum creatinine in umol/L.
scr.conversion.factor	Numeric. A factor for converting serum creatinine from umol/L to mg/dL.
IDMS	Logical. TRUE if IDMS correction should be used.

Details

All arguments can be vectors. Albumin and BUN are optional. If they are specified, a more elaborate version of the MDRD equation is used.

# With serum creatinine in mg/dL
egfr_mdrd(scr.mg.dL=0.9, age.yr=53, is.female=FALSE, is.black=FALSE)

# With serum creatinine in umol/L
egfr_mdrd(scr.umol.L=0.9*88.4, age.yr=53, is.female=FALSE, is.black=FALSE)
