Therefore, clinicians need accurate ways to estimate this key number. The most important reason is to screen patients for the presence of chronic kidney disease, so that appropriate treatment can be initiated. If a person is known to have chronic kidney disease, then clinicians will want to monitor GFR over time to determine if kidney function is remaining stable or not. If GFR falls too low, then plans need to be made for renal replacement therapy, such as dialysis or transplantation. Finally, certain drugs are eliminated by the kidney, and doses need to be reduced when GFR falls below certain thresholds. Typically GFR is reported not in liters per day, but in milliliters per minute. Furthermore, it is now standard to normalize this number for body surface size, or 1.73 m2.
