WebAs of January 2013, many large commercial clinical laboratories have changed from using the MDRD Study equation to the CKD-EPI Creatine 2009 Equation for eGFR reporting. *O=non African American (non in 2024 Eq). Cr=creatinine. Cys=cystatin. Eq=Equation. WebWhen evaluating a patient’s GFR, it is important to remember that eGFR is an estimate of the patient’s GFR. For eGFR cr and eGFR cys (calculated from cystatin C), 80-90% of values are within 30% of measured GFR. eGFR cr-cys (calculated using both creatinine and cystatin C) is more accurate than either eGFR cr or eGFR cys alone.
