Kidney Function Test (KFT)
Kidneys help in removing the waste products from our bodies. They also help in regulating pH levels by regulating the levels of electrolytes in the body. If the kidneys fail to function properly, waste materials accumulate and cause damage to the body. The Kidney Function Test is used in determining the health and functioning of kidneys. The tests that are ordered to evaluate the functioning of the kidneys include blood urea nitrogen and creatinine blood.
