Does eGFR using the combination of creatinine and cystatin C improve accuracy compared to measured GFR in persons with discordant eGFRcr or eGFRcys?
Using a combination of creatinine and cystatin C provides the most accurate eGFR in patients where the individual estimates are discordant.
Discordant eGFRcr and eGFRcys are common. eGFR using the combination of creatinine and cystatin C provides the most accurate estimates among persons with discordant eGFRcr or eGFRcys.
