    What is Estimated Glomerular Filtration Rate (eGFR) Test?

    The Estimated Glomerular Filtration Rate (eGFR) test is a diagnostic blood test that determines how efficiently your kidneys filter blood each minute. Found near the waist on either side of your spine, the kidneys contain glomeruli, small filtration units responsible for removing waste and excess fluids from the blood and excreting them through urine.

    When kidney function is impaired, often due to kidney disease, the filtration process slows down. A low eGFR may suggest kidney failure, which could require dialysis or a kidney transplant.

    The eGFR test serves the following purposes:

    • Identifying kidney disease in asymptomatic individuals

    • Confirming kidney disease in people with symptoms

    • Determining the stage of kidney disease progression

    • Tracking the effectiveness of chronic kidney disease (CKD) treatment

    • Assessing kidney health in patients on potentially nephrotoxic medications

    • Evaluating kidney function before starting treatments that may impact kidney performance

    This test is a cornerstone of early detection, precise diagnosis, and comprehensive kidney care.

    Estimated Glomerular Filtration Rate (eGFR) Test Parameters

    The eGFR test, or estimated glomerular filtration rate test, evaluates how much blood the kidneys filter each minute.

    This test is a crucial indicator of kidney function. Although the glomerular filtration rate (GFR) can be directly measured, it is a complicated process not typically used. Instead, eGFR is estimated using a blood test to measure creatinine, a waste product formed during normal muscle activity. High blood levels of creatinine may point to diminished kidney function.

    The calculation of eGFR incorporates factors such as age, height, weight, and sex alongside creatinine levels. These factors help account for variations in creatinine production due to body size, diet, and physical activity, providing a more accurate estimate.

    Cystatin C, another biomarker, can also be used to determine eGFR. This protein, produced by all body cells, is unaffected by diet, muscle mass, or age, making it a useful alternative in certain cases. Combining creatinine and cystatin C is being researched as a potentially more comprehensive approach to assessing kidney health.

    The eGFR test is indispensable for evaluating kidney health and identifying potential issues early.

    Estimated Glomerular Filtration Rate (eGFR) Test Preparation

    Consider these details before arranging an Estimated Glomerular Filtration Rate (eGFR) test in Gurgaon:

    • Prerequisites

    No fasting is necessary before taking this test.

    • Best Time to Get Tested

    You can take this test at any time of the day.

    • Who Should Get This Test

    People with a higher risk of kidney disease, such as those with diabetes, high blood pressure, or a family history of kidney problems, should undergo this test.

    • Cautions Before Taking This Test

    No special preparations are typically needed, but consulting your doctor beforehand is advised to ensure it’s the right choice for you.

    Why Take the Estimated Glomerular Filtration Rate (eGFR) Test?

    The eGFR test is essential for detecting chronic kidney disease (CKD) at its onset, as the condition rarely shows symptoms in its early stages. This test is particularly recommended for individuals with increased risk factors, such as:

    • Diabetes : A leading cause of kidney damage over time.

    • High Blood Pressure : Puts strain on kidney blood vessels.

    • Obesity : Excess body weight can harm kidney function.

    • Age Above 60 : Aging increases vulnerability to kidney issues.

    • Family History of CKD or Kidney Failure : Genetic predisposition can contribute to CKD risk.

    CKD often develops from a combination of health, environmental, and social factors.

    By the time symptoms become apparent, CKD is frequently in advanced stages. Common signs include:

    • Frequent or reduced urination

    • Chronic itching

    • Persistent tiredness

    • Swelling in the feet, legs, or arms

    • Feeling nauseous or vomiting

    • Muscle cramps

    • Loss of appetite

    The eGFR test provides critical insights for early detection and monitoring of kidney health.
