Importance of KFT:kidney function test The kidneys, two bean-shaped organs located in the abdomen, perform vital functions such as filtering waste products from the blood, regulating fluid and electrolyte balance, and producing hormones essential for red blood cell production. Any impairment in renal function can lead to severe health complications. KFT, including the RFT, helps identify abnormalities in kidney function, allowing for early detection and timely intervention. The Role of RFT in KFT: Renal Function Test (RFT) is a fundamental part of KFT that examines various parameters to evaluate kidney function accurately. It involves analyzing blood and urine samples to measure specific markers indicative of renal health. The RFT encompasses several key parameters, including serum creatinine, blood urea nitrogen (BUN), estimated glomerular filtration rate (eGFR), and urine analysis. Serum Creatinine:  Serum creatinine is a waste product generated by muscle metabolism and eliminate
