What is the RFT Test?
Renal Function Test (RFT) is a comprehensive panel that evaluates how well your kidneys are working. It measures creatinine, urea, uric acid, electrolytes (sodium, potassium, chloride), calcium, and phosphorus. Your kidneys filter 200 litres of blood daily — RFT checks whether they're keeping up with this critical job.
