<s>[INST] Hi, i have Transplanted Kidney given by my mother, i am facing the Protein Leak Problem and Creatinine is 1.66My doctor suggested me to get the extended KFT done. I want to know what is Extended KFT. I searched on the net but it shows only KFT. Could you please guide me? [/INST] Hello and welcome to HCM.As an Urologist,i assure you, there's nothing to worry about extended KFT.As KFT means kidney function test,extended KFT,only means you'll need some more tests, as you've a protein leak problem.In extended KFT, usually tests include checking CBC,urea,creatinine,calcium,electrolytes,proteins,uric acid,FBS and urine routine.    Hope your doubt's cleared.For my expert opinion,on any doubt,you can send it, as a direct question.Dr.Matthew J. Mangat. </s>
