The eGFR test, also known as the estimated glomerular filtration rate test, is a blood test used to assess kidney function. This test measures the amount of waste and excess fluid that the kidneys are filtering out of the blood. The results of the eGFR test can help diagnose and monitor kidney disease and other kidney-related conditions.

Definition of eGFR Test

The eGFR test is a blood test that measures the amount of waste and excess fluid that the kidneys are filtering out of the blood. The test calculates the eGFR, which is the estimated glomerular filtration rate, based on the creatinine level in the blood and other demographic factors, such as age, sex, and race.

The eGFR is a measure of the amount of blood that is filtered by the kidneys each minute. A normal eGFR is between 90 and 120 milliliters per minute per 1.73 square meters of body surface area. A lower eGFR indicates that the kidneys are not functioning properly and may indicate the presence of kidney disease or other kidney-related conditions.

Purpose of eGFR Test

The main purpose of the eGFR test is to assess kidney function and to diagnose and monitor kidney disease and other kidney-related conditions. The test can also be used to monitor the progression of kidney disease and to evaluate the effectiveness of treatment for kidney-related conditions.

Diagnosis of Kidney Disease

The eGFR test is often used to diagnose kidney disease. A decrease in the eGFR can indicate that the kidneys are not functioning properly and may indicate the presence of kidney disease. If the eGFR is low, further testing may be necessary to determine the cause of the decrease and to diagnose kidney disease.

Monitoring Kidney Disease

The eGFR test is also used to monitor kidney disease. If a person has been diagnosed with kidney disease, regular eGFR tests can be used to monitor the progression of the disease and to evaluate the effectiveness of treatment. A decrease in the eGFR over time may indicate that the disease is progressing and that treatment may need to be adjusted.

Assessing Kidney Function Before and After Surgery

The eGFR test may also be used to assess kidney function before and after surgery, especially if the surgery is related to the kidneys or urinary tract. The test can help determine if the kidneys are functioning properly and if there is any need for further testing or treatment before or after surgery.

Interpretation of eGFR Test Results

The results of the eGFR test are expressed as a number in milliliters per minute per 1.73 square meters of body surface area. A normal eGFR is between 90 and 120 milliliters per minute per 1.73 square meters of body surface area. However, the normal range may vary depending on factors such as age, sex, and race.

A lower eGFR indicates that the kidneys are not functioning properly and may indicate the presence of kidney disease or other kidney-related conditions. If the eGFR is less than 60 milliliters per minute per 1.73 square meters of body surface area, it is considered to be abnormal and may indicate the presence of kidney disease or other kidney-related conditions.

It is important to note that the eGFR test is an estimate and not a direct measurement of kidney function. The test results may be affected by factors such as dehydration, recent use of contrast dye, and certain medications. Therefore, it is important to discuss the test results with a healthcare provider to determine the best course of action.

Conclusion

The eGFR test is a blood test used to assess kidney function. The test measures the amount of waste and excess fluid that the kidneys are filtering out of the blood and calculates the estimated glomerular filtration rate (eGFR). The main purpose of the eGFR test is to diagnose and monitor kidney disease and other kidney-related conditions. The results of the eGFR test can help determine if the kidneys are functioning properly and if there is a need for further testing or treatment. It is important to discuss the test results with a healthcare provider to determine the best course of action.
