Kidney Function Tests

Kidney Function Tests (KFT/RFT) – Essential Evaluation of Renal Health

Kidney Function Tests (KFT), also referred to as Renal Function Tests (RFT), are a set of blood and urine investigations used to assess how well the kidneys are working. These tests are crucial for detecting kidney disease, monitoring kidney health in chronic conditions like diabetes and hypertension, and evaluating the body’s ability to eliminate waste and maintain electrolyte balance.

Key parameters included in the KFT panel are:

• Urea and Creatinine: These are waste products filtered out by the kidneys. Elevated levels indicate impaired kidney filtration and are common in acute or chronic kidney disease.

• Uric Acid: High levels may suggest reduced kidney function or conditions like gout, which may also affect kidney health.

• Electrolytes – Sodium (Na), Potassium (K), and Chloride (Cl): These minerals are regulated by the kidneys and are vital for nerve function, hydration, and acid-base balance. Imbalances may signal kidney dysfunction or dehydration.

• Calcium and Phosphorus: The kidneys help regulate these minerals. Abnormal levels can indicate kidney-related bone disorders or chronic renal disease.

KFTs help diagnose a variety of conditions such as glomerulonephritis, nephrotic syndrome, urinary tract obstructions, and chronic kidney disease (CKD). They are also critical in monitoring patients on nephrotoxic drugs or those undergoing dialysis.

Early detection through KFTs allows for timely intervention, slowing the progression of kidney disease and preventing complications. Regular screening is especially recommended for individuals with risk factors like high blood pressure, diabetes, or a family history of kidney disease.
