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 · Chronic kidney disease (CKD) is when your kidneys are damaged and not working properly to filter your blood. Your doctor will use two tests to determine how well your kidneys are working: a blood test and a urine test. The blood test checks your estimated glomerular filtration rate (eGFR) or the amount of creatinine, a waste product, in your blood.

In the absence of evidence of kidney damage, neither GFR category G1 nor G2 fulfill the criteria for CKD. Abbreviations: ACR, albumin-to-creatinine ratio; CKD, chronic kidney disease. *Relative to young adult level. **Collectively referred to as “CGA Staging”

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.

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.

CKD is classified based on the eGFR and the level of proteinuria and helps to risk stratify patients. Patients are classified as G1-G5, based on the eGFR, and A1-A3 based on the ACR (albumin:creatinine ratio) as detailed below: For Example. A person with an eGFR of 25 ml/min/1.73m² and an ACR of 15 mg/mmol has CKD G4A2.

Estimates GFR in CKD patients using serum creatinine, cystatin C, or both. The 2021 CKD-EPI equation is now the recommended standard. This version does not include race, as do the 2009 and 2012 CKD-EPI creatinine and creatinine-cystatin C equations. See here for more on our approach to addressing race and bias on MDCalc.

Glomerular Filtration Rate (GFR) is the standard measure of kidney function. Measurement of true GFR is not practical in routine clinical practice as it is time consuming and expensive. Therefore, standardised formulae have been developed to calculate estimated GFR (eGFR).

2025年1月3日 · eGFR (estimated glomerular filtration rate) is a measure of how well your kidneys are working. Your eGFR is an estimated number based on a blood test and your age, sex, and body type. eGFR is considered a mostly reliable test …
