GFR is a test that helps measure the level at which an individual's kidney is functioning. It is calculated on the basis of factors such as age, gender, race, and blood creatinine. Normal GFR values are between 90 to 120 ml/min. A GRF below 60 ml/min could mean that some kidney damage has occurred.
A blood sample is sent to laboratory. Serum creatinine will be factored with age, race, height and weight to calculate your glomerular filtration rate (GFR). Normal range of glomerular filtration rate (GFR) will decrease with age increasing.The result of GFR will confirm how much the kidneys have been damaged and the stage of chronic kidney disease. The normal range of GFR is above 90ml/min.A GFR result of 60 to 90ml/min is an abnormal condition, indicating stage 2 chronic kidney disease; but the diagnosis should be made on the basis that the patient has any of the following evidence of kidney disease:he normal range of GFR is above 90ml/min. A GFR result of 60 to 90ml/min is an abnormal condition, indicating stage 2 chronic kidney disease; but the diagnosis should be made on the basis that the patient has any of the following evidence of kidney disease:
