A Kidney Function Test (KFT), also called Renal Function Test (RFT), is a group of blood tests that evaluate how well the kidneys are working. It measures waste products and minerals that the kidneys are responsible for filtering.
KFT includes parameters like serum creatinine, blood urea nitrogen (BUN), uric acid, electrolytes (sodium, potassium, chloride), and sometimes calcium and phosphorus. It is essential for patients with diabetes, hypertension, or kidney disease.
