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

A kidney function test, also called a renal function test, is designed to assess kidney function. It is done by measuring key biochemical parameters, including urea, uric acid, creatinine, and minerals. Kidneys filter these products from the body and regulate the levels of important minerals, such as calcium. In cases of kidney disorders, levels of these parameters may exceed the normal range and show up in your lab reports, even before symptoms occur. This aids in early detection and timely medical care.

Kidney function tests are used to screen and diagnose individuals at high risk or with symptoms, as well as to monitor patients with existing kidney disorders.

Your doctor may recommend a KFT under the following conditions:

• Diabetes, high blood pressure, or heart disease
• Pre-existing kidney disease
• Family history of kidney disease
• People on long-term medications such as painkillers or antibiotics
• Signs of a kidney disease
• Age over 60
• Kidney donor

Signs of Kidney Disease:

If you notice any of the following signs, they might be suggestive of a kidney disorder:

• Persistent fatigue
• Swollen feet, ankles, or under-eye area
• Changes in frequency of urination
• Foamy or frothy urine
• Changes in urine colour
• Loss of appetite
• Muscle cramps

KFTs can help detect and monitor various kidney conditions, such as :

• 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 impact kidney function results.

What to Expect Before the KFT Test

• Fasting is usually not required for a kidney function test when performed alone.
• Inform your doctor about all current medications, as they can alter test results.
• Always consult your healthcare provider for any special instructions to follow before the test.

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

What to Expect During the Blood Collection

A small blood sample is required for testing and collected using the procedure 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.
• Feeling dizzy for a few seconds is normal and usually resolves with rest.

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

KFT parameters are a combination of waste products, minerals, or electrolytes that determine the efficiency of kidney function. The parameters included in a KFT are 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. Consistently elevated creatinine levels may indicate reduced kidney function.
• eGFR: checks how well kidneys are filtering waste, 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.

The table below gives the normal reference ranges of kidney function test parameters:

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 your lab reports.

Interpretation of kidney function test results requires professional evaluation for accurate diagnosis.
