Kidney Function Test (KFT) in Bengaluru - Price & Details

A kidney function test, also known as a renal function test, is a blood test used to assess how well your kidneys are functioning. Any underlying kidney disorders may or may not produce any external symptoms, but can show up as elevated levels of waste products in your test reports. Kidney function tests help detect underlying conditions early and prevent further damage.

Kidney diseases can occur silently, making the kidney function test necessary, especially for the following groups:

• Patients with diabetes, hypertension, or heart disease
• Patients with ongoing kidney disease
• Anyone with a family history of kidney disease
• Anyone who has swelling in the legs, feet, or around the eyes
• Patients on long-term medications such as painkillers or antibiotics
• Anyone experiencing changes in urine output or urine colour
• Elderly adults (over 60)
• Kidney donors

Kidney function tests aid in the detection of the following conditions at the earliest:

• Chronic kidney disease (CKD): a gradual loss of kidney function over months or years.
• Acute kidney injury: sudden decrease in kidney function over hours or days.
• Kidney failure: severe reduction or complete loss of kidney function.
• Gout: high levels of uric acid in the blood may increase the risk of gout.
• Mineral imbalances: calcium imbalances may lead to bone disorders.
• Kidney stones: high uric acid or calcium in the blood increases the risk of kidney stones.
• Dehydration: low body fluid levels can affect kidney function results.

What to Expect Before the KFT Test

• No fasting is required for a standalone kidney function test.
• Inform your doctor about all current medications.
• Always consult your healthcare provider for any special instructions beforehand.

Note: Certain medications (painkillers, antibiotics, antihypertensives), dietary protein levels, or dehydration status can alter test results.

What to Expect During the Blood Collection

A blood sample is the only requirement for this test, collected from the vein of your inner arm. The steps for the same are given below:

• An elastic band is tied around your upper arm for better access to veins.
• The skin is cleaned with an antiseptic, and a needle is inserted into the vein.
• The needle is withdrawn after the sample is collected, and a bandage is placed over the site to prevent minor bleeding.

What to Expect After the KFT Test

• The test procedure is generally safe with minimal to no risks.
• If dizzy, sit and relax for a few minutes to recover.

Note: If you notice bruising, pain, or a rash at the puncture site after the test, consult your healthcare provider.

Kidney function is assessed through its ability to clear out waste products efficiently, and can be evaluated using the parameters given below:

• Uric acid test: measures uric acid levels to assess risk of gout and kidney filtration.
• Blood urea nitrogen (BUN)/serum urea test: evaluates nitrogen waste levels to assess kidney efficiency.
• Calcium (Ca) test: the kidneys regulate calcium levels. Abnormal calcium levels may indicate mineral or bone-related disorders.
• Creatinine test: creatinine is a waste product from muscle activity. Elevated creatinine levels may indicate reduced kidney function.
• eGFR: a more reliable marker of kidney function, calculated using creatinine, age, and gender.
• BUN/creatinine ratio: helps differentiate kidney disease from other causes of kidney dysfunction, such as dehydration.
• Urea/creatinine ratio: assists in evaluating causes of urea imbalance.
• Urea (calculated): measures blood urea levels, helping assess kidney filtration.

Refer to the table below for the normal reference ranges of kidney function tests:

Note: The normal values and reference ranges of the test may vary from lab to lab. Please refer to the ranges mentioned in the report and consult a doctor to understand the interpretation of lab reports.

Any type of kidney dysfunction can impact the levels of certain waste products in the blood. To understand more, refer to the table below:
