Calculates GFR (kidney glomerular filtration rate) from the serum creatinine level and subject age, sex, and race.
Accepts serum creatinine measured by the new IDMS method (adjusted for isotope-dilution mass spectrometry) or by older methods.
Uses both the new 2009 CKD-EPI equation, and the older MDRD equation for which it gives results based on both IDMS-adjusted and older, non-adjusted, serum creatinine values.
Accepts creatinine in either mg/dL or micromoles/L.
