Kidney Function Tests (KFT)

The Kidney Function Test (KFT) is a routine blood test that helps evaluate how efficiently your kidneys are filtering waste from your body. Your kidneys play a vital role in removing toxins, balancing fluids, and maintaining healthy levels of minerals like sodium and potassium. When they are not functioning properly, the body may not show clear symptoms in the early stages — which is why regular testing becomes important.

A KFT usually measures key parameters such as serum creatinine, blood urea, uric acid, and electrolyte levels. These values help doctors understand whether your kidneys are functioning normally or if there are early signs of kidney stress, infection, or chronic kidney disease.

This test is commonly recommended for individuals who:

• Have diabetes or high blood pressure

• Experience swelling in the feet or face

• Feel unexplained fatigue

• Have changes in urination patterns

• Have a family history of kidney disease

The procedure is simple and requires only a blood sample. Results are typically available within a short time, allowing timely medical guidance if needed.

Regular monitoring through a Kidney Function Test can help detect kidney issues early, making treatment more effective and preventing long-term complications.
