Kidney Function Test: Understanding Your KFT Results

The kidneys play a vital role in maintaining the body’s internal balance by filtering waste products, regulating fluids, and maintaining electrolyte levels. When doctors suspect kidney problems, they often recommend a Kidney Function Test (KFT). Understanding your KFT results can help detect kidney disease early and guide appropriate treatment.

At Tambaram Medical Center, our specialists provide advanced diagnostic services to evaluate kidney health and treat kidney-related conditions for patients across Tambaram and Chennai.

Kidney function tests measure creatinine, urea and other markers to evaluate kidney health.

What Is a Kidney Function Test (KFT)?

A Kidney Function Test is a group of blood and urine tests used to evaluate how well the kidneys are working. These tests measure waste products, minerals, and proteins in the blood to determine whether the kidneys are filtering properly.

Common Tests Included in KFT

• Serum Creatinine
• Blood Urea Nitrogen (BUN)
• Estimated Glomerular Filtration Rate (eGFR)
• Uric Acid
• Electrolytes such as sodium and potassium

You can learn more about creatinine levels here: Creatinine Levels Explained.

Why Are Kidney Function Tests Important?

KFTs help doctors detect kidney disease in its early stages, monitor chronic kidney disease, and evaluate the effectiveness of treatment.

• Persistent fatigue
• Changes in urination
• High blood pressure
• Nausea or vomiting
