Cause of CKD is classified based on presence or absence of systemic disease and the location within the kidney of observed or presumed pathologic-anatomic findings on kidney biopsy or imaging. Determining the cause of CKD distinguishes whether the patient has a systemic condition or a localized condition in the kidney such as glomerular disease ...

2025年3月18日 · Stage 1 CKD means you have a normal eGFR of 90 or greater and mild damage to your kidneys. Your kidneys are still working well, so you may not have any symptoms. You may have other signs of kidney damage, such as protein in your urine, which can be detected by a uACR test. Learn more about stage 1 chronic kidney disease (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.

A more modern classification of chronic kidney disease (CKD) is based on estimated GFR, and recognises five stages of kidney disease, as follows (1,2): Stage 1: Normal GFR; GFR >90 mL/min/1.73 m2 with other evidence of chronic kidney damage; Stage 2: Mild impairment; GFR 60-89 mL/min/1.73 m2 with other evidence of chronic kidney damage

Chronic kidney disease (CKD) is when the kidneys have become damaged over time (for at least 3 months) and have a hard time doing all their important jobs. CKD also increases the risk of other health problems like heart disease and stroke. Developing CKD is usually a very slow process with very few symptoms at first.

Why Classify CKD? Abbreviations: CGA, Cause, GFR category and albuminuria category; CKD, chronic kidney disease; GFR, glomerular filtration rate. Note: Patients above the thick horizontal line are likely to be encountered in nephrology practice.

We recommend initiating SGLT-2 inhibition in people with chronic kidney disease, irrespective of primary kidney disease,* for any of the following clinical scenarios: a) eGFR of ≥20 mL/min/1.73m² and a urinary albumin-to-creatinine ratio (uACR) of ≥25 mg/mmol† b) Symptomatic heart failure, irrespective of ejection fraction

The ACR is used to calculate the ‘A stage’ of CKD (as indicated in the Stages of CKD chart below). There are three recognised stages of albuminuria: A1 – normal to mildly increased urine protein levels (lower than 3mg/mmol)

Guidelines for the Management of Chronic Kidney Disease (CKD) for Adults What is CKD? CKD is the presence of one of the following for>3 months. Offer Screening for CKD using eGFR, serum creatinine and Urine Albumin: Creatinine Who to Test Ratio (UACR) to people with any of the following risk factors:
