What is LAB value EGFR?

The estimated glomerular filtration rate (eGFR) is a lab value used to assess kidney function. It is a measure of how well your kidneys filter waste from your blood and is an essential indicator of overall kidney health.

What factors are evaluated to determine eGFR?

The eGFR is calculated by considering factors such as your age, gender, race, and the results of a blood test that measures creatinine levels.

How is eGFR calculated?

To calculate eGFR, a formula called the Modification of Diet in Renal Disease (MDRD) equation is typically used. The equation uses creatinine levels, along with other factors, to estimate the glomerular filtration rate.

What is creatinine?

Creatinine is a waste product produced by muscle metabolism. It is filtered out of the blood by the kidneys and expelled in urine. Higher levels of creatinine in the blood indicate reduced kidney function.

Why is eGFR important?

eGFR is a vital tool used by healthcare professionals to evaluate kidney function and diagnose kidney disease. It helps determine the stage of kidney disease and guides appropriate treatment strategies.

What are the normal eGFR levels?

A normal eGFR is usually above 90 mL/min/1.73m². Values below this can indicate kidney dysfunction.

What does eGFR below 60 mL/min/1.73m² indicate?

An eGFR below 60 mL/min/1.73m² indicates impaired kidney function and is usually a sign of chronic kidney disease.

What does eGFR below 15 mL/min/1.73m² indicate?

An eGFR below 15 mL/min/1.73m² indicates advanced kidney failure or end-stage renal disease and may require dialysis or kidney transplantation.

What are the causes of low eGFR values?

Low eGFR values can be caused by various factors, including kidney disease, dehydration, high blood pressure, certain medications, and underlying health conditions like diabetes.

Can eGFR be improved?

In some cases, underlying conditions causing decreased eGFR can be treated, and measures can be taken to slow the progression of kidney disease and improve kidney function.

Do I need to fast before an eGFR test?

Fasting is generally not required for an eGFR test. However, certain medications and substances like creatine supplements may affect creatinine levels and should be avoided prior to the test.

Can eGFR be measured at home?

While a blood test is required to obtain an accurate eGFR measurement, there are home test kits available that allow individuals to collect a blood sample and send it to a lab for analysis.

How often should eGFR be measured?

The frequency of eGFR measurement depends on your specific health condition and the recommendations of your healthcare provider. Generally, it is done at least once a year for individuals with stable kidney function.

In conclusion, the eGFR is a crucial lab value that provides insight into kidney function and helps diagnose and monitor kidney disease. By understanding our eGFR levels, we can take necessary steps to maintain kidney health and manage any existing kidney conditions effectively.
