At this time, all laboratories should be using creatinine methods calibrated to be isotope dilution mass spectrometry (IDMS) traceable. Numerous equations using the serum creatinine level have been developed to calculate estimated GFR (eGFR) ( Box 2 ). This calculator is for people aged 18 years or older. We hypothesized that serum creatinine by itself might not be a great marker because growth occurs in children, and with growth is the accretion of muscle mass, which raises serum creatinine.
