When the filtration rate decreases that means the kidneys are not working well and may mean there is kidney damage [2]. For example, if eGFR is reported based on the non-African American equation, a comment could state "For African Americans, multiply by 1.212, for the MDRD equation, or 1.159 for the CKD-EPI equation." .
