Abbreviations: CKD, chronic kidney disease; GFR, glomerular filtration rate. *Relative to young adult level. In the absence of evidence of kidney damage, neither GFR category G1 nor G2 fulfill the criteria for CKD.

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.

Screen for CKD with two simple tests. Spot urine for albumin-to-creatinine ratio (ACR) to detect albuminuria; Serum creatinine to estimate glomerular filtration rate (GFR) Classify CKD to guide testing and treatment. Assign GFR category; Assign albuminuria category; Determine prognosis of CKD based on GFR and albuminuria category (see chart below)

2025年3月18日 · What do the stages of chronic kidney disease (CKD) refer to? CKD is broken into five stages or categories based on your eGFR value. The five stages of CKD refer to how well your kidneys are working. Kidney disease can get worse in time. In the early stages (Stages 1–3), your kidneys are still able to filter waste out of your blood.

see if their kidneys are healthy or if they have chronic kidney disease, also called CKD. Having CKD means that you’ve had a kidney problem for at least 3 months.

The eGFR and albuminuria grid depicts the risk of progression, morbidity, and mortality by color, from lowest to highest (green, yellow, orange, red, deep red). The numbers in the boxes are a guide to the frequency of assessment annually.

There are 5 stages of chronic kidney disease (CKD), from very mild kidney damage in stage 1 to complete kidney failure in stage 5. The stages of kidney disease are based on the estimated glomerular filtration rate, or eGFR number, which measures how well your kidneys filter waste and extra fluid from your blood.

Chronic kidney disease is defined by the presence of kidney damage or decreased kidney function for at least three months, irrespective of the cause. 2 Kidney damage generally refers to pathologic anomalies in the native or transplanted kidney, established via imaging, biopsy, or deduced from clinical markers like increased albuminuria— that is,...

As progression of CKD is defined as either a progressive decrease in GFR or a progressive increase in albuminuria, we should consider separately whether different factors would predict these two components of CKD differently.

The Kidney Failure Risk Equation (KFRE) is a well-validated risk prediction tool for a kidney replacement therapy (KRT) in the next two or five years in individuals with chronic kidney disease (CKD) stages 3a-5.
