Introduction
Your kidneys play a critical role in filtering waste and excess fluids from the blood. They help balance your body’s minerals, produce hormones that regulate blood pressure, and manage red blood cell production. To ensure that your kidneys are functioning properly, doctors often recommend a kidney function test. This test gives an overview of how well your kidneys are working and whether there might be any signs of damage or disease.
One common concern people have before undergoing medical investigations is the kidney function test cost. Understanding the components of the test, its purpose, the kidney function test name options, and what the kidney function test normal values look like can prepare you better for both the procedure and its results.
This blog covers everything you need to know, from why this test is important to what the average renal function test EGFR and other indicators show.
What is a Kidney Function Test?
A kidney function test is a series of blood and urine tests that evaluate how well your kidneys are filtering blood and managing waste. These tests help detect early signs of kidney damage, chronic kidney disease, or acute kidney conditions.
Some of the most common kidney function test name options include:
-
Serum Creatinine Test
-
Blood Urea Nitrogen (BUN)
-
Estimated Glomerular Filtration Rate (eGFR)
-
Urinalysis
-
Albumin-to-Creatinine Ratio (ACR)
These tests are non-invasive and require either a blood sample, urine sample, or both.
Kidney Function Test Cost in India
The kidney function test cost in India can vary depending on several factors such as the city, diagnostic center, and whether the test is conducted at a hospital or an independent lab. On average, the cost of kidney function test ranges from ₹300 to ₹1500.
Here is a breakdown of cost based on the components:
| Test Component | Average Cost (INR) |
|---|---|
| Serum Creatinine | ₹100 – ₹300 |
| Blood Urea Nitrogen (BUN) | ₹150 – ₹350 |
| eGFR | Usually included |
| Complete Kidney Profile | ₹400 – ₹1500 |
| Urine ACR | ₹200 – ₹500 |
You may also find bundled offers at diagnostic labs that provide a full kidney profile at a discounted rate. Always check whether the price includes consultation and follow-up.
When is a Kidney Function Test Recommended?
Doctors may recommend this test if:
-
You have symptoms like swelling in feet, ankles, or face
-
You experience frequent urination or blood in urine
-
You have high blood pressure or diabetes
-
You are on medication that can affect the kidneys
-
You have a family history of kidney disease
-
You are undergoing treatment for a known kidney condition
Early detection can prevent long-term complications, so never ignore the signs.
Types of Kidney Function Tests
There is no single kidney function test name that covers everything. Instead, a combination of tests gives a full picture of your kidney health. Let us look at the most common ones.
1. Serum Creatinine Test
This measures the level of creatinine in the blood. Creatinine is a waste product that comes from muscle metabolism and is removed by the kidneys. High levels suggest reduced kidney function.
2. Blood Urea Nitrogen (BUN)
This test calculates the amount of nitrogen in the blood that comes from urea, a waste product formed by the liver. An elevated BUN level can indicate impaired kidney function.
3. eGFR (Estimated Glomerular Filtration Rate)
The renal function test eGFR estimates how much blood passes through the glomeruli each minute. A value under 60 may suggest kidney disease.
4. Urinalysis
This includes several tests to detect protein, glucose, blood, and other substances in the urine. Presence of protein can indicate kidney damage.
5. Albumin-to-Creatinine Ratio
This test checks for small amounts of albumin in the urine. High levels are an early sign of kidney disease.
Kidney Function Test Normal Range
Knowing the kidney function test normal value helps interpret your results accurately. Always consult a doctor to analyze your reports, but here are average ranges:
| Test | Normal Range |
|---|---|
| Serum Creatinine (Men) | 0.7 to 1.3 mg/dL |
| Serum Creatinine (Women) | 0.6 to 1.1 mg/dL |
| BUN | 7 to 20 mg/dL |
| eGFR | ≥ 90 mL/min/1.73 m² (Normal) |
| ACR (Albumin-to-Creatinine Ratio) | Less than 30 mg/g |
These kidney function test normal range values can vary depending on age, gender, and overall health.
Symptoms That Indicate Kidney Problems
-
Persistent fatigue
-
Swelling in hands, feet, or face
-
Nausea and vomiting
-
Reduced urine output
-
Foamy or bloody urine
-
High blood pressure
-
Difficulty concentrating
If you notice any of these signs, speak to your healthcare provider about scheduling a kidney function test.
Preparing for a Kidney Function Test
Generally, no special preparation is required. However, some tips include:
-
Stay hydrated unless told otherwise
-
Inform your doctor about all medications
-
Follow any fasting instructions, if required
These tests are quick and cause minimal discomfort. Results are usually available within a few hours or by the next day.
Understanding Your Kidney Test Results
A kidney function test helps detect:
-
Acute Kidney Injury (AKI)
-
Chronic Kidney Disease (CKD)
-
Kidney infections or inflammation
-
Obstructions in urinary tract
-
Risk levels for people with diabetes or hypertension
If values are outside the kidney function test normal range, your doctor may recommend lifestyle changes, medication, or further tests like ultrasound or biopsy.
Kidney Function Test and Chronic Kidney Disease
Chronic Kidney Disease often has no symptoms in the early stages. Regular testing is the only way to detect it. The renal function test eGFR is the most effective tool to monitor disease progression. Based on the kidney function test results, CKD is staged from 1 (normal) to 5 (kidney failure).
Maintaining a healthy lifestyle, managing blood pressure, and avoiding nephrotoxic drugs can slow down progression.
How Often Should You Get the Test?
The frequency of testing depends on your risk factors:
-
Healthy individuals: once every 1–2 years
-
Diabetics or hypertensives: every 6–12 months
-
People with kidney disease: as advised by a nephrologist
Early detection leads to better management and can delay or prevent kidney failure.
Ways to Keep Your Kidneys Healthy
-
Drink enough water
-
Avoid excess salt and processed foods
-
Control blood sugar and blood pressure
-
Exercise regularly
-
Avoid overuse of painkillers
-
Get tested regularly if you’re at risk
Taking care of your kidneys should be a lifelong commitment, especially if you fall into a high-risk category.
