eGFR, Estimated GFR

While you may not know it, the kidneys are responsible for a lot of work every day. The kidneys filter waste products from the blood, produce the right amounts of fluid and minerals in the body, control blood pressure, and keep the entire body functioning properly. Unfortunately, many people who have kidney problems don't have any symptoms at all until they are much later into the disease. eGFR testing is just one type of lab test that can help to determine how well your kidneys are working right now and how well they will continue to work in the future.

At City Imaging, we recognise the value of obtaining an early diagnosis of the kidneys. Our expert laboratory provides an efficient and accurate eGFR test, which will enable your healthcare provider to know whether or not your kidneys are functioning normally, to provide early warning signs of potential kidney problems, and to detect kidney problems earlier than if no diagnostic testing was done. The price of an eGFR test ranges from INR 200 to INR 600.

What is an eGFR Test?

An estimation of glomerular filtration rate can be calculated based on creatinine levels, age and sex to see how effectively the kidneys clear waste out of your bloodstream

Although an eGFR is not an actual measurement of how well your kidneys function, it is a calculated estimate of the amount of blood flowing through your kidneys every minute.

Why is the eGFR Test important?

The test is especially useful for:

• Detecting chronic kidney disease
• Monitoring kidney function over time
• Evaluating the effects of diabetes
• Assessing kidney function before certain medical procedures
• Determining whether medications need dosage adjustments
• Monitoring kidney health after treatment

Who should get an eGFR Test?

Your doctor may recommend an eGFR test if you:

• Have diabetes
• Have high blood pressure
• Have a family history of kidney disease
• Are over the age of 60
• Experience swelling in the legs, ankles, or feet
• Notice blood or protein in your urine
• Have persistent fatigue without a clear cause
• Have recurrent urinary tract infections

• Take medications that may affect kidney function

How is the eGFR Test performed?

During the procedure:

1. A healthcare professional cleans the skin over a vein, usually in your arm.
2. A small needle is inserted to collect a blood sample.
3. The sample is sent to the laboratory for analysis.
4. The laboratory measures your serum creatinine level.
5. Your eGFR is calculated using validated medical equations.

• Stay well hydrated unless instructed otherwise.

Generally:

• 90 mL/min/1.73 m² or above: Normal Kidney Function (in absence of any other symptoms consistent with kidney disease)
• 60–89: Mild Decline in Kidney Function, which can be within normal limits for some patients, but should be interpreted along with other clinical findings
• 30–59: Moderate Kidney Dysfunction
• 15–29: Severe Kidney Dysfunction
• <15: End Stage Renal Disease requiring urgent medical intervention

Frequently Asked Questions (FAQs)

How much pain is involved with an eGFR test?

You will only have a quick blood draw done for the eGFR. There will be a quick pin prick when the needle goes in, but this should feel similar to any other blood draw you get since it only takes seconds and is typically well tolerated by everyone.

Fasting before an eGFR test?

Generally speaking, if your doctor did not specifically say to fast before you come in for your test then fasting usually is not required. If your healthcare provider gave you any special instructions you should follow those.

Does a lower than normal eGFR value always mean I have kidney disease?

No. There are many factors that can affect how your eGFR test results; these include things like: age, getting sick for a short time, being dehydrated, certain medications & more. Your doctor will look at all of these factors & consider your medical history in order to understand your eGFR test results properly.

When should I get another eGFR test done?

This depends on many things such as your overall health status, whether you have any history of diabetes, hypertension and chronic kidney disease, etc.

Can kidneys get better?

In certain situations, kidneys can recover from an illness by treating whatever caused the illness; for example, treating dehydration, stopping medications, resolving urinary obstruction, others.
