Question

What is meant by glomerular filtration rate? How does it affect the filtration process?

Answer 1

Glomerular filtration rate (GFR) is a test used by physicians and other medical professionals to see if the kidneys are working correctly. In basic terms, it is a measurement of how much liquid and waste is passing from the blood through the tiny filters in the kidney, called the glomeruli, and out into the urine during each minute. The test measures how much creatinine is in the blood. This shows how well the kidneys are performing.
A GFR of less than 60ml/minute for three or more months indicates chronic kidney disease. A GFR of less than 15ml/minute indicates full failure of the kidneys. GFR estimates between 60 and 89 mL/minute do not mean a person has chronic kidney disease unless there are other signs of disease.
