A simple urine test called the urine Albumin:Creatinine ratio (ACR) is also performed to look for signs that protein is leaking into the urine (a condition called albuminuria or proteinuria). So, a GFR of 60 means you may have function that is 60% of normal. All Rights Reserved. Most people reading this booklet will be at stage 4 or 5.

Kidney function evaluation by means of creatininebased estimation equations on line medical reference from definition and diagnosis through danger factors and remedies. See chart below for average estimated eGFR based on age. A normal GFR is around 100 ml/min/1.73m2, Because the average normal eGFR is 100, the eGFR can be seen as a percentage of normal kidney function. Kidney Research UK is a registered charity no. Results consistently below 60mL/min/1.73m2 indicate chronic kidney disease. 5 percent kidney function means that your kidneys have failed to do their normal work, and your illness condition also has progressed into end stage renal disease (ESRD), which is the last stage of kidney disease. eGFR calculator. Explaining your kidney test results Your GFR result on on _____ (Date), was _____. There are three recognised stages of albuminuria: Combining your ACR ratio with your eGFR can help doctors try to predict whether your kidney disease is likely to progress and whether you are more likely to develop complications such as heart and circulatory problems. What stage is patient in with 40% kidney function? The ACR is used to calculate the ‘A stage’ of CKD (as indicated in the Stages of CKD chart below). SC039245. This is often referred to as a percentage of kidney function. By using a blood test to measure creatinine levels we can calculate the estimated GFR, known as eGFR. Symptoms of 20 Percent Kidney Function. Other factors are also taken into account, e.g. eGFR is calculated from blood test results using a formula that looks at the level of creatinine (a waste product) in your blood. Serum Creatinine * µmol/L . All rights reserved. Typically, a simple urine test will also be done to check for blood or albumin (a type of protein) in the urine. It is not accurate at near-normal levels, so many labs report eGFR over 60 as just ">60" (more than 60). Your kidney function is still considered normal if the GFR number is 90 or greater. The National Kidney Foundation recommends using the CKD-EPI Creatinine Equation (2009) to estimate GFR. Estimated Glomerular Filtration Rate (eGFR) Brochure, Calculate your Glomerular Filtration Rate (GFR). The presence of blood or protein in the urine may alert a doctor that there is kidney damage causing mild kidney disease. 14% kidney function indicate the condition has developed into end stage renal disease. Your GFR tells your doctor your stage of kidney disease and helps the doctor plan your treatment. Because the average normal eGFR is 100, the eGFR can be seen as a percentage of normal kidney function. Abnormal kidney function may cause too much or too little urine to be produced. The GFR (glomerular filtration rate) is a measure of how much blood (in millilitres) is ‘cleaned’ by the kidneys in one minute. In general, the higher the ‘A’ stage, the more likely it is that you will benefit from blood pressure-lowering treatment. However, if you have only 20% kidney function, you may experience marked changes, which include: Anemia. The eGFR calculation can be inaccurate in people who have much more, or much less muscle than average people of their age, sex, and ethnic origin. stage 5 (G5) – an eGFR below 15ml/min, meaning the kidneys have lost almost all of their function ; Your ACR result is given as a stage from 1 to 3: A1 – an ACR of less than 3mg/mmol ; A2 – an ACR of 3 to 30mg/mmol ; A3 – an ACR of more than 30mg/mmol ; For both eGFR and ACR, a higher stage indicates more severe kidney disease. This chart shows the stages of kidney disease and outlines how disease is likely to progress if kidney function reduces and urine protein levels increase. Glomerular filtration rate (GFR) is the best overall index of kidney function. As normal eGFR is round about 100, the eGFR gives you an approximate 'percentage function'. Your doctor will want to investigate the cause of your kidney disease and continue to check your kidney function to help plan your treatment.

So if your eGFR is 50, your kidneys are probably filtering at about 50% of normal. The Mayo Quadratic Formula: - The GFR = e (1.911 + 5.249/S Cr - 2.114/S Cr 2 - 0.00686 * Age - (0.205 only if Female)). The efficiency of clearance is measured using the GFR. In adults, the normal eGFR number is more than 90. eGFR declines with age, even in people without kidney disease. You also have the option to opt-out of these cookies. However, values as low as 60 are considered normal if there is no other evidence of kidney disease, The eGFR is used to calculate the ‘G stage’ of CKD (as indicated in the Stages of CKD chart).

"Normal" GFR is approximately 100 but you will often see it reported as >90 (greater than 90) or >60 (greater than 60).

GFR (glomerular filtration rate) is the reliable indicator of kidney function. eGFR stands for estimated Glomerular Filtration Rate. For instance, it can be falsely low in body builders, and falsely high in people with anorexia nervosa. These cookies do not store any personal information.
