Chronic Kidney Disease

Definition of Chronic Kidney Disease (CKD)

• Chronic Kidney Disease (CKD) is characterized by a gradual loss of kidney function over time.
• It is measured by the glomerular filtration rate (GFR) and is defined as kidney damage or a GFR of less than 60 mL/min/1.73 m² for three months or longer.

Classification of Chronic Kidney Disease (CKD)

• CKD is classified into five stages based on the level of GFR and extent of kidney damage.
• The stages range from G1 (normal or high GFR) to G5 (kidney failure requiring dialysis or transplantation).

GFR Category for G3a in CKD Staging

• G3a corresponds to a GFR category of 45-59 mL/min/1.73 m².
• This stage reflects mild to moderate decrease in kidney function.

GFR Category for G4 in CKD Staging

• G4 corresponds to a GFR category of 15-29 mL/min/1.73 m².
• This stage indicates severe decrease in kidney function, often requiring close monitoring and potential preparation for dialysis.
