If glomerular filtration rate of 32.8ml/min is caused by acute kidney injury, then it can usually be elevated after active treatment, while if it is caused by chronic kidney disease, glomerular filtration rate usually cannot be elevated. Under normal condition, glomerular filtration rate is 80~120ml/min, while when glomerular filtration rate is 32.8ml/min, it suggests that glomerular filtration function is impaired. Acute kidney injury: there are three kinds: pre-renal, renal and post-renal. In case of pre-renal such as blood volume insufficiency and post-renal such as stones, glomerular filtration rate can usually be increased after rehydration therapy and stone removal therapy. Chronic Kidney Disease: In case of chronic kidney disease, glomerular filtration rate usually cannot be recovered after decreasing, and the purpose of treatment is mainly to slow down the decline of renal function and prevent and control complications, etc. Patients with low glomerular filtration rate should go to the hospital as soon as possible, and standardize the treatment under the guidance of professional physicians, and should not delay the condition.
