2023年11月19日 · Chronic kidney disease (CKD) is divided into five stages, ranging from stage 1 to stage 5. Each stage is determined by a blood test known as the estimated glomerular filtration rate (eGFR), which establishes how well your kidneys filter waste and …

2022年7月13日 · Your kidneys filter your blood by removing waste and extra water to make urine. The glomerular filtration rate (GFR) shows how well the kidneys are filtering. An estimated 37 million adults in the United States may have chronic kidney disease (CKD) but nearly 90% are unaware of their condition.

2025年3月18日 · Stage 4 CKD means you have an eGFR between 15 and 29 and moderate to severe damage to your kidneys. Your kidneys do not work as well as they should to filter waste out of your blood.

Glomerular filtration rate (GFR) is the best overall index of kidney function. Normal GFR varies according to age, sex, and body size, and declines with age. The National Kidney Foundation (NKF) and the American Society of Nephrology (ASN) convened a Task Force in 2021 to focus on the use of race when estimating GFR.

CKD is evaluated using two simple tests – a blood test known as the estimated glomerular filtration rate (eGFR) and a urine test known as the urine albumin-creatinine ratio (uACR). Both tests are needed to have a clear picture of your kidney health.

2019年1月14日 · The GFR chart by age and CKD stages table provides valuable reference points for both patients and healthcare professionals to understand and interpret kidney function test results.

2021年6月17日 · Healthcare providers use estimated glomerular filtration rate (eGFR) to determine if you have kidney disease, and if so, what stage. eGFR measures your kidneys’ ability to filter toxins or waste from your blood. A very low number may indicate kidney failure, which requires dialysis or a kidney transplant.

2023年9月13日 · eGFR（CKD-EPI）里所有年龄组的女性和男性分别连续下降8.4 mL/min/1.73m²/十年和6.9 mL/min/1.73m²/十年。 该项研究结果表明，女性的eGFR高于男性，随着年龄的增长，女性的eGFR下降速度快于男性。

How do you check for CKD? A blood test and a urine test are used to find kidney disease. Because you are at risk, you should get these tests regularly: GFR - A blood test measures how much blood your kidneys filter each minute, which is known as your glomerular filtration rate (GFR). Urine Albumin - A urine test checks for albumin in your urine.

2024年7月31日 · Chronic kidney disease (CKD) is characterized by the presence of kidney damage or an estimated glomerular filtration rate (eGFR) of less than 60 mL/min/1.73 m², persisting for 3 months or more. CKD involves a progressive loss of kidney function, often leading to the need for renal replacement therapy, such as dialysis or transplantation.
