What is GFR in blood test
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.our 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. GFR on a blood test stands for Glomerular Filtration Rate. This test is used to used to test how well the kidneys are working. It estimates how much blood passes through the filters in the kidney, called the glomeruli, every minute.The normal value for GFR is 130-140 ml /min of creatinine(a substance used to check kidney functioning). glomerular filteration rate, this test is done to check the kidney function.GFR stands for glomerular flow rate. It provides an index for the function of the kidneys. normal GFR or Glomerular Filtration Rate, is similar in both men and women. For adults it is between 100-130 ml/min/1.73m2. For children a GFR at 110 ml/min/1.73m2 is normal … . GFR's are used to assess kidney damage or 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.he 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 level of creatinine in the blood is a useful guide to kidney function, but GFR (glomerular filtration rate) is a more accurate measure. Blood creatinine can be used to estimate GFR (eGFR) using age, sex, and race, and this is often calculated by computer and reported along with the creatinine blood test.he level of creatinine in the blood is a useful guide to kidney function, but GFR (glomerular filtration rate) is a more accurate measure. Blood creatinine can be used to estimate GFR (eGFR) using age, sex, and race, and this is often calculated by computer and reported along with the creatinine blood test. 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.ormal 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. A blood test for eGFR or estimated glomuler filtration rate is a measurement used to check for the stage of renal failure that a person is experiencing.This is a test that is quite complicated and requires a trained nephrologist to perform.n eGFR blood test is used whenever there is suspicion of a kidney disease. This is usually the case in patients who are suffering from diabetes or from hypertension for a prolonged period of time. An eGFR blood test maybe recommended by your doctor to determine the creatinine levels in the blood. The test reveals kidney function and indicates how well or poorly your kidneys are filtering the creatinine (waste produced through muscle function) from your blood.n eGFR blood test is used whenever there is suspicion of a kidney disease. This is usually the case in patients who are suffering from diabetes or from hypertension for a prolonged period of time. The inside of a glomerulus showing the filter. Glomerular filtration rate (GFR) is a test used by physicians and other medical professionals to see if the kidneys are working correctly.he inside of a glomerulus showing the filter. Glomerular filtration rate (GFR) is a test used by physicians and other medical professionals to see if the kidneys are working correctly. Creatinine clearance in a healthy young person is about 125 milliliters per minute -- meaning each minute, that person's kidneys clear 125 mL of blood free of creatinine. The GFR can vary depending on age, sex, and size. Generally, the creatinine clearance is a good estimation of the glomerular filtration rate.ormal 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. The eGFR is a calculation based on a serum creatinine test. Creatinine is a muscle waste product that is filtered from the blood by the kidneys and excreted into the urine at a relatively steady rate. When kidney function decreases, less creatinine is excreted and concentrations increase in the blood.he 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.
GFR on a blood test stands for Glomerular Filtration Rate. This test is used to used to test how well the kidneys are working. It estimates how much blood passes through the filters in the kidney, called the glomeruli, every minute.
