eGFR equations are mathematical formulas used to estimate the glomerular filtration rate (GFR), which is a key indicator of kidney function. These equations take into account serum creatinine levels, age, sex, and sometimes race, providing a more accurate assessment of kidney health than serum creatinine alone.

Glomerular Filtration Rate (GFR) is a critical measure of kidney function that quantifies how well the kidneys filter blood, typically expressed in milliliters per minute. It is used to assess kidney health, diagnose kidney disease, and guide treatment decisions, with lower rates indicating impaired kidney function.

Serum Creatinine Levels

Age is a measure of the time a person or object has existed, influencing biological, psychological, and social dimensions of life. It impacts identity, opportunities, and societal roles, and is often used to categorize stages of development and aging processes.

Race is a socially constructed category used to group people based on physical characteristics such as skin color, but it has no biological basis. It plays a significant role in shaping social dynamics, influencing identity, and perpetuating systemic inequalities.

Accurate assessment of kidney health

Serum creatinine is a waste product in the blood that comes from muscle activity and is an important indicator of kidney function. Elevated levels can suggest impaired kidney function or kidney disease, making it a critical parameter in diagnosing and monitoring renal health.
