What Is Normal Glomerular Filtration Rate (GFR) For Age?

Glomerular filtration rate (GFR) is a test used to measure how well the kidneys are functioning. It is an important marker of overall kidney health that can be used to help diagnose and monitor chronic kidney diseases. The GFR for any particular age group can be an important indicator as to how a person’s kidneys are performing.

What Is GFR?

GFR is a measure of how well the kidneys are performing. It is calculated using a formula that takes into account the concentrations of certain chemicals found in the blood, including creatinine, urea, and potassium. The calculated value can then be used to assess how well the kidneys are functioning.

How Is GFR Used To Assess Overall Kidney Health?

A normal GFR can indicate that there are no major issues with the kidneys and that they are functioning normally. A low GFR may indicate the presence of a kidney disease. A persistently low or high GFR can be an indication of a more serious underlying issue and should be investigated further.

What Is A Normal GFR For Age?

The normal range for GFR for adults is 90 to 150 mL/min per 1.73 m2. The normal range can vary slightly depending on a person’s age, as well as other factors such as gender and body size. Generally, as people get older, their GFR gradually declines.

For ages 40 to 49, GFR should be around 128 mL/min per 1.73 m2. For ages 50 to 59, GFR should be around 118 mL/min per 1.73 m2. For ages 60 to 69, GFR should be around 107 mL/min per 1.73 m2. For ages 70 to 79, GFR should be around 90 mL/min per 1.73 m2.

Conclusion

GFR is an important test to measure the functioning of the kidneys and can help diagnose and monitor a variety of kidney diseases. It is important to be aware of a person’s normal GFR for their age, as this value can vary based on age and other factors. A persistently low or high GFR can be an indication of a more serious underlying issue and should be investigated further.
