estimate_gfr_schwartz: Estimate creatinine clearance and glomerular filtration rate...

In LS31/clinicalcalculations: Clinical calculations

Description

The Schwartz formula is used in children: \frac{36.2 \times \text{height}}{\text{creatinine}}.

Usage

estimate_gfr_schwartz(creatinine, height)

Arguments

creatinine	Creatinine (\text{μmol} \text{l}^{-1}).
height	Height (cm).

Value

eGFR (\text{ml} \text{min}^{-1} 1.73 \text{m}^{-2}), or NA if any parameters are NA.

Caveats

This is the revised (2009) formula with the same factor κ for all age categories: 36.2. The returned value is based on a standardised body surface area of 1.73 m^2.
