The Glomerular Filtration Rate (GFR) test is a blood test that measures how well the kidneys are functioning. The kidneys filter waste and excess fluids from the blood, and the GFR measures how much blood the kidneys can filter per minute. The test is used to detect early signs of kidney damage or disease, as well as to monitor the progression of existing kidney conditions. The GFR is calculated based on several factors, including age, gender, and creatinine levels in the blood. A low GFR result may indicate decreased kidney function, and further testing may be required to determine the cause of the impairment. The GFR test is a useful tool for doctors to help diagnose and manage kidney disease, and it can also help patients make lifestyle changes to protect their kidney health.
