What is the recommended glomerular filtration rate for stage 3b CKD?

The correct range for the glomerular filtration rate (GFR) in stage 3b chronic kidney disease (CKD) is 30-44 mL/min/1.73 m². This classification helps healthcare providers evaluate kidney function and guide treatment decisions.

Stage 3 CKD is divided into 3a and 3b, with stage 3b indicating a more advanced decrease in kidney function compared to stage 3a. The ranges for glomerular filtration rates are established by the National Kidney Foundation and typically recognize stage 3a as having a GFR of 45-59 mL/min/1.73 m² and stage 3b as having a GFR of 30-44 mL/min/1.73 m².

Understanding these classifications is vital, as they provide not only insight into the severity of kidney disease but also the prognosis and potential need for interventions such as lifestyle changes or medications to slow disease progression. Familiarity with these ranges is essential for healthcare professionals managing patients with kidney disease.
