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

Kidney function tests, also known as renal function tests, are a group of tests that assess the function of your kidneys. Kidneys are vital organs that remove waste from the body, maintain fluid balance, and regulate blood pressure. Certain underlying health conditions or medications can silently damage the kidneys. Therefore, kidney function tests are important for detecting early damage, monitoring kidney function, and tracking disease progression.

The risk of kidney disease is high among the following groups, and they should consider getting kidney function tests done:

• 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 help detect the following conditions:

• 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 Kidney Function 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 as follows.

• 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• The needle is withdrawn once the sample is collected.

What to Expect After the Kidney Function Test

• A bandage is placed over the site to stop any minor bleeding.
• If you feel 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 tests measure the filtering efficiency of the kidneys through various parameters, explained below:

• Uric acid test: measures uric acid levels to assess the 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.

The inability of the kidneys to filter waste products efficiently leads to abnormal levels of these products in the blood, indicating the presence of certain underlying conditions. To understand more, refer to the table below:
