Third stage kidney disease

10/09/2007

Question:

Please explain third stage kidney disease.

Answer:

Stage 3 chronic kidney disease means that there is a moderate loss of kidney function. The normal renal function is expressed by the glomerular filtration rate (GFR). The normal GFR is 90-120 cc/min. Stage 3 means the GFR is 30 to 59 cc/min. The GFR is determined with a blood test called the serum creatinine. This creatinine is plugged into a formula that reflects your age,gender and race. This formula is an estimate of your GFR.
