GFR (Glomerular Filtration Rate)
Only ₹200

A GFR test (Glomerular Filtration Rate test) is used to check how well your kidneys are working. It measures how effectively your kidneys filter waste and excess fluid from your blood.
The GFR is usually estimated using a blood creatinine test along with factors such as age, gender, and body size. Doctors may recommend this test if you have diabetes, high blood pressure, kidney disease symptoms, or a family history of kidney disorders. An abnormal GFR result can help identify kidney damage at an early stage, allowing timely treatment and better management to prevent further complications.

GFR (Glomerular Filtration Rate) Test –
What is a GFR (Glomerular Filtration Rate) test?
The GFR test measures how efficiently your kidneys filter waste products and excess fluids from your blood. It is an important indicator of overall kidney function.
Why is the GFR test performed?
Doctors recommend a GFR test to detect kidney disease, monitor existing kidney conditions, and assess kidney function in people with diabetes, high blood pressure, or other risk factors.
Do I need to fast before a GFR test?
Fasting is usually not required for a GFR test. However, your doctor may provide specific instructions if additional blood tests are being performed at the same time.
What is a normal GFR value?
A normal GFR is generally 90 mL/min/1.73 m² or higher, although the normal range may vary depending on age and overall health.
What does a low GFR result indicate?
A low GFR may indicate reduced kidney function or chronic kidney disease (CKD). Your doctor may recommend additional tests to determine the underlying cause.
How often should I get a GFR test?
The frequency depends on your health condition. People with kidney disease, diabetes, or high blood pressure may need regular GFR testing as advised by their healthcare provider.
What is GFR?
GFR (Glomerular Filtration Rate) is the amount of blood filtered by tiny units in the kidneys (called glomeruli) per minute.
Types of GFR Tests
1. Estimated GFR (eGFR)
- Most common test
- Calculated from a blood test measuring Creatinine
- Also considers age, gender, and sometimes ethnicity
2. Measured GFR (mGFR)
- More accurate but less commonly done
- Uses special substances injected into the blood and tracked in urine
Normal GFR Values
- 90 or above → Normal kidney function
- 60–89 → Slightly reduced (may be normal in older adults)
- Below 60 → Possible kidney disease
- Below 15 → Kidney failure
Why is the GFR Test Important?
It helps diagnose and monitor:
- Chronic Kidney Disease
- Acute Kidney Injury
- Effects of conditions like Diabetes and High Blood Pressure
Symptoms of Low GFR (Kidney Problems)
- Swelling in legs/feet
- Fatigue
- Decreased urine output
- Nausea or confusion
Before the Test
- Fasting: Usually not required, but your doctor may ask you to avoid heavy protein meals (like meat) before the test.
- Medications: Inform your doctor about all medicines you take (some may affect Creatinine levels).
- Avoid intense exercise: Heavy workouts before the test can temporarily increase creatinine levels.
During the Test
- A blood sample is taken from a vein in your arm.
- Sometimes a urine sample may also be collected.
- The procedure is quick and usually takes only a few minutes.
After the Test
- You can return to normal activities immediately.
- Drink water to stay hydrated.
