eGFR

Estimated Glomerular Filtration Rate (eGFR) is a crucial measure of kidney function, estimating how effectively the kidneys filter waste and excess fluids from the blood. It is derived from the levels of creatinine in the blood, along with factors such as age, sex, and body size. eGFR is expressed in milliliters per minute per 1.73 meters squared (mL/min/1.73 m²) and helps identify and monitor kidney health.

An eGFR of 90 mL/min/1.73 m² or higher is typically considered normal, while lower values indicate varying degrees of kidney dysfunction. eGFR is essential for diagnosing and staging chronic kidney disease (CKD), with stages ranging from mild (stage 1) to kidney failure (stage 5). This measure guides treatment decisions, helps in managing conditions like diabetes and hypertension that affect kidney health, and informs about the potential need for dialysis or kidney transplantation. Regular eGFR testing is vital for early detection and effective management of kidney-related conditions.
