Plasma cystatin C level might better reflect glomerular filtration rate (GFR) than creatinine concentration. Ma et al. have developed and tested a new equation to estimate GFR that uses cystatin C ...

Serum cystatin C levels are influenced by factors other than glomerular filtration rate (GFR), a retrospective analysis suggests. Serum concentration of cystatin C has been proposed as a more ...

A worldwide movement is underway to oblige laboratories to provide an estimated glomerular filtration rate (eGFR) whenever serum creatinine concentration is measured at the request of a physician.

Objective Many societies recommend using estimated glomerular filtration rate (eGFR) rather than serum creatinine (sCr) to determine metformin eligibility. We examined the potential impact of ...
