GFR-glomerular filtration rate is the best test to measure your level of kidney function and determine your stage of kidney disease.
Glomerular filtration rate (GFR) is a measure of the function of the kidneys. This test measures the level of creatinine in the blood and uses the result in a formula to calculate a number that reflects how well the kidneys are functioning, called the estimated GFR or eGFR. The GFR refers to the amount of blood that is filtered by the glomeruli per minute. As a person's kidney function declines due to damage or disease, the filtration rate decreases and waste products begin to accumulate in the blood. The blood test, called GFR, measures how much blood your kidneys filter each minute. Your doctor uses this information to see how well your kidneys are working. A GFR of over 60 means your kidneys are working fine. A GFR of 60 or lower may mean you have kidney disease.  Here's what you want to know: The glomerular filtration rate (GFR) is a measure of your kidney function, or the health of your kidneys. ... GFR number, which can be checked through a blood test, gives you an idea of how well your kidneys are working ... What is a normal GFR number ... Chronic Kidney Disease www.lifescript.com/health/a-z/conditions_a-z/conditionsindepth/c/chronic_kidney_disease.aspx. Anatomy of the Kidneys. GFR-glomerular filtration rate is the best test to measure your level of kidney function and determine your stage of kidney disease. Your doctor can calculate it from the results of your blood creatinine test, your age, body size and gender. Your GFR tells your doctor your stage of kidney disease and helps the doctor plan your treatment. If your GFR number is low, your kidneys are not working as well as they should. The earlier kidney disease is detected, the better the chance of slowing or stopping its progression In this article. Creatinine is a waste product from the normal breakdown of muscle tissue. As creatinine is produced, it's filtered through the kidneys and excreted in urine. Doctors measure the blood creatinine level as a test of kidney function. The kidneys ' ability to handle creatinine is called the creatinine clearance rate, which helps to estimate the glomerular filtration rate (GFR) -- the rate of blood flow through the kidneys. Normal Kidney Function and the GFR. All the blood in the body flows through the kidneys hundreds of times each day. The kidneys push the liquid part of blood through tiny filters (called nephrons), then reabsorb most of the fluid back into the blood. Glomerular filtration rate (GFR). An effective way of assessing how well your kidneys are working is to calculate your glomerular filtration rate (GFR). GFR is a measurement of how many millilitres (ml) of waste fluid your kidneys can filter from the blood in a minute (measured in ml/min).  Renal function, in nephrology, is an indication of the state of the kidney and its role in renal physiology. Glomerular filtration rate (GFR) describes the flow rate of filtered fluid through the kidney. Creatinine clearance rate (CCr or CrCl) is the volume of blood plasma that is cleared of creatinine per unit time and is a useful measure for approximating the GFR.  Various different diseases, conditions and medicines can affect the function of the kidneys. The estimated glomerular filtration rate (eGFR) does not diagnose any kidney disease but is a test to assess how well your kidneys are working. The test is called the estimated glomerular filtration rate because the glomeruli are the tiny filters in the kidneys. If these filters do not do their job properly then the kidney is said to have reduced or impaired kidney function. The eGFR is a test that is used to assess how well your kidneys are working. The test estimates the volume of blood that is filtered by your kidneys over a given period of time. The test is called the estimated glomerular filtration rate because the glomeruli are the tiny filters in the kidneys. If these filters do not do their job properly then the kidney is said to have reduced or impaired kidney function. The eGFR test involves a blood test which measures a chemical called creatinin Glomerular filtration is the process by which the kidneys filter the blood, removing excess wastes and fluids. Glomerular filtration rate (GFR) is a calculation that determines how well the blood is filtered by the kidneys, which is one way to measure remaining kidney function. GFR is also used to find the stage of chronic kidney disease. Glomerular filtration rate is usually calculated using a mathematical formula that compares a person's size, age, sex, and race to serum creatinine levels.
