A new equation for calculating a person's kidney function — their estimated glomerular filtration rate (eGFR) — worked as well with serum cystatin C as it did with serum creatinine as the biomarker.

The glomerular filtration rate (GFR) is an indicator of kidney function; in the clinic, it is not practical to measure this routinely, so it is estimated from serum creatinine and/or cystatin C levels ...
