EITHAR - Kidney Function Test (KFT) - ( RFT)

During the metabolism of protein in the body, the liver creates ammonia, which is broken down into a by-product called urea. Kidneys filter excess urea into the urine and in sweat, but some goes into the bloodstream as serum urea.

This test measures how well your kidneys are performing their job of filtering waste from your blood. Creatinine is a chemical compound left over from energy-producing processes in your muscles. Healthy kidneys filter creatinine out of the blood. Creatinine exits your body as a waste product in urine
