The stages of chronic kidney disease reflect on the overall function of the kidneys, and help risk-stratify an individual’s kidney health. This risk stratification guides treatment planning, and can have implications on other aspects of health, including whether certain medications can be taken.
Blood tests and urine analyses are used to determine the stage of kidney disease. A Glomerular Filtration Rate (GFR) is calculated. A higher number indicates a better kidney function. Generally speaking, the following categories are used:
• At risk screening and preventative management (Stage 1, GFR >90mL/min) • Early disease (Stage 2,3a,3b, GFR 30-90) • Late or severe disease, where conservative care or renal replacement options are discussed (Stages 4,5 GRF <30)
