CAPA paediatric cystatin C eGFR (2014)

Source: R/pediatric.R
egfr_capa.Rd

Estimates GFR from serum cystatin C using the Caucasian, Asian, paediatric, and adult (CAPA) equation (Grubb et al., 2014).

Usage

egfr_capa(cystatin, age)

Arguments

cystatin

Numeric vector of serum cystatin C in mg/L.

age

Numeric vector of age in years.

Value

Numeric vector of eGFR in mL/min/1.73m^2.

Validity

Derived in 4690 subjects spanning children and Caucasian and Asian adults, and intended for use across all ages. Note that CAPA is known to return implausibly high estimates in children under 10 years.
