The estimated glomerular filtration rate (eGFR) is a measure of kidney function that helps in diagnosing and monitoring kidney diseases. It is important to understand that the normal range of eGFR can vary depending on a person’s age. In this article, we will explore the EGFR normal range by age and its significance in assessing kidney health.

The eGFR is calculated using a formula that takes into account a person’s age, gender, race, and serum creatinine levels. It is expressed in milliliters per minute per 1.73 square meters (mL/min/1.73m²). The normal range of eGFR is generally considered to be above 60 mL/min/1.73m².

In children, the normal range of eGFR is higher compared to adults due to their higher metabolic rate. For infants and toddlers, an eGFR above 90 mL/min/1.73m² is considered normal. As children grow older, the normal range gradually decreases. In adolescents, a normal eGFR is typically above 80 mL/min/1.73m².

In adults, the normal range of eGFR is generally between 90-120 mL/min/1.73m². However, as individuals age, kidney function naturally declines. Therefore, the normal range for older adults may be slightly lower, with an eGFR above 60 mL/min/1.73m² still considered within the normal range.

It is important to note that the eGFR is just one of the factors used to assess kidney function. Other tests, such as urine analysis and imaging studies, may also be necessary to get a comprehensive evaluation.

Understanding the EGFR normal range by age is crucial in assessing kidney health. It helps healthcare professionals determine if a person’s kidney function is within the expected range for their age group. Regular monitoring of eGFR can aid in the early detection and management of kidney diseases. If you have concerns about your kidney health, it is always best to consult with a healthcare professional who can provide personalized advice and guidance.
