An Estimated Glomerular Filtration Rate (eGFR) test is conducted to assess kidney function by calculating how much blood your kidneys filter per minute. Located on both sides of the spine near the waist, the kidneys house small filtering units called glomeruli. These structures remove waste and excess fluids from the bloodstream, which are eliminated via urine.

Impaired kidney function, often due to conditions like kidney disease, hampers this filtration process. A low eGFR can indicate kidney failure, necessitating treatments such as dialysis or transplantation.

The eGFR test is typically used for:

• Screening for kidney disease in those without symptoms

• Diagnosing kidney disease in symptomatic individuals

• Identifying the stage of kidney disease progression

• Monitoring chronic kidney disease (CKD) and treatment outcomes

• Checking kidney function in people using potentially harmful medications

• Assessing kidney health prior to therapies that could impact kidney performance

This test is essential for early detection, accurate diagnosis, and effective management of kidney-related conditions.

If you’re planning to take an Estimated Glomerular Filtration Rate (eGFR) test in Delhi, here are some important factors to consider:

• Prerequisites

You don’t need to fast before undergoing this test.

• Best Time to Get Tested

The eGFR test can be performed at any time of the day.

• Who Should Get This Test

Individuals at higher risk for kidney disease—such as those with diabetes, high blood pressure, or a family history of kidney conditions—should consider this test.

• Cautions Before Taking This Test

Although no preparation is usually required, consulting with your doctor beforehand is recommended to confirm the test’s suitability.

The eGFR test plays a critical role in identifying chronic kidney disease (CKD) at an early stage when symptoms may not yet be evident. This test is often recommended for those at higher risk of CKD due to factors such as:

• Diabetes : A common cause of kidney damage.

• High Blood Pressure : Increases stress on kidney blood vessels.

• Excess Weight : Can impair kidney function.

• Age Above 60 : Kidney-related problems become more prevalent with age.

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

The development of CKD often stems from a mix of physical health concerns, environmental exposures, and social determinants.

By the time symptoms appear, CKD is usually in later stages. These symptoms can include:

• Changes in urination patterns (too frequent or too rare)

• Ongoing itching

• Severe fatigue

• Swelling in the extremities, such as the hands or feet

• Nausea and vomiting

• Muscle pain or cramps

• Loss of appetite

The eGFR test is a valuable tool for early diagnosis and monitoring of kidney health.
