KIDNEY FUNCTION TEST(KFT)

Kidney Function Test (KFT)

The Kidney Function Test (KFT) is a comprehensive blood and biochemical test panel used to evaluate how well your kidneys are functioning. It helps assess the kidneys’ ability to filter waste products, maintain fluid balance, regulate electrolytes, and support overall metabolic health.

The kidneys are vital organs responsible for removing toxins and excess fluids from the blood. When kidney function becomes impaired, harmful waste products can build up in the body, leading to serious health complications. The KFT test helps detect kidney disease early, monitor chronic kidney conditions, and evaluate treatment effectiveness.

A standard KFT panel commonly includes:

• Blood Urea Nitrogen (BUN)
• Serum Creatinine
• Uric Acid
• Sodium
• Potassium
• Chloride
• Calcium
• Phosphorus
• Estimated Glomerular Filtration Rate (eGFR)

These markers help doctors understand kidney filtration efficiency and detect early signs of kidney dysfunction.

Benefits of the Test

• Detects kidney disease early
• Monitors chronic kidney disorders
• Evaluates electrolyte balance
• Helps assess dehydration and fluid imbalance
• Monitors treatment response
• Detects complications related to diabetes and hypertension
