You will have a blood test to see how much of a waste product called creatinine is in your blood. This number, along with your age, race, and gender are used to estimate your GFR. GFR stands for glomerular (glow-MAIR-you-lure) filtration rate. Your GFR number tells you how well your kidneys are working to filter out wastes and extra fluid from your body.
GFR is reported as a number.
You will have a urine test to see if there is protein called albumin (al-BYOO-min) in your urine. A healthy kidney does not let albumin pass into the urine. A damaged kidney lets some albumin pass into the urine. The less albumin you have in your urine the better.
If you have an abnormal urine albumin level or a low GFR number, your doctor will order more tests to see what might be causing these results. Further testing and evaluation are very important because:
