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 ...

In clinical practice, eGFR is most often computed using creatinine (can sometimes overestimate GFR), cystatin C (can underestimate GFR), or a combination of the two (the best estimate).

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 ...
