In this lesson, you will learn about GFR; what it measures as well as what levels are considered normal in a healthy human. The blood test and calculations used to determine GFR will also be described. Main Functions of the Kidney
These tests measure the levels of certain chemicals in the blood as well as the urine that are indicative of how well the kidneys are functioning. For patients with a history of kidney disease in their families, or, that already have risk factors for kidney disease such as diabetes, high bl...
Before the blood test, you may need to: Stop taking prescription or over-the-counter (OTC) drugs. Fast (not eat or drink). Avoid some foods. Your doctor will tell you how to prepare for the blood test. Back to top What Is a Normal GFR for My Age?
The glomerular filtration rate (GFR) is a measure of how well your kidneys are removing waste from your blood, which can be determined using an estimated GFR (eGFR) test. The test gets its name from glomeruli -- the parts of your kidney that filter out waste. (Photo credit: Image Source...
A more widely available but less accurate alternative is the creatinine clearance test, which typically requires collection of urine over a 24-hour period.测定GFR的标准方法是测量外源性滤过标志物的清除率,例如奥他拉明的尿液清除率。一种更广泛但不太准确的替代方法是...

a blood test for creatinine (used to estimate glomerular filtration rate (gFR) even if these tests are normal now, they should be repeated in the future, especially if you are at increased risk for kidney disease. (see page 8) www. KidNey.oRg 3 Wouldnt I know if something was wrong ...
However, if the kidneys are not functioning normally there will be a high level of creatinine in the blood. The glomerular filtration rate is so-called because the test determines how well the glomeruli, the tiny filters inside the kidney, are doing their job. What does the GFR number ...
min per 1.73 m2;1.21) = 186.3 x Serum Creatinine (exp[-1.154]) x Age (exp[-0.203]) x (0.742 if female) x (1.21 if african american)To use this formula to gain an idea of your GFR, you should input your age, gender, race and you also need creatinine levels from your blood ...
Glomerular filtration rate (GFR) is a test used to check the functioning levels of the kidneys. Specifically, it estimates how much blood passes through the glomeruli (tiny filters) in the kidneys. GFR also tells you how much kidney function you have. The sample for the test is the blood...
