If the glomerular filtration rate is 60 mL/min, it belongs to stage 2 of chronic kidney disease. The stage of chronic kidney disease is classified according to the value of the patient’s glomerular filtration rate. If the glomerular filtration rate is above 90mL/min and the patient has other physical and chemical changes of kidney disease, it belongs to stage 1 of chronic kidney disease. If the glomerular filtration rate is between 60-89 mL/min, it is classified as stage 2 chronic kidney disease. If the glomerular filtration rate is between 30-59 mL/min, it belongs to stage 3 of chronic kidney disease. If the glomerular filtration rate is between 15-30mL/min, it belongs to stage 4 of chronic kidney disease. When the glomerular filtration rate is less than 15mL/min, it belongs to stage 5 of chronic kidney disease, which is end-stage kidney disease, and the patient should take dialysis treatment. If the glomerular filtration rate is 60mL/min, it is in stage 2, and the patient should be treated early, combined with other symptoms to see if kidney preservation drugs are needed, and early treatment.
