Creatinine is a waste material that comes from the normal execution of the muscles in the body. It is eliminated by the kidneys as it is present in the blood during the blood filtration process. Creatinine levels in the blood can signify the low kidney function or the abnormal functionality of the kidneys and consequently creatinine treatment is needed to propagate kidney function. Each kidney has millions of filters called nephrons which are the tiny filter known as glomeruli and tubules. The blood is passed through the glomeruli where the waste, excess water and other impurities are removed. The role of the tubule is to absorb the important nutrients and return them back into the blood if in case the glomeruli are not able to retain them. The waste is then passed to the bladder as urine from where it is eliminated. Having elevated levels of creatinine is one of the significant factors to evaluate kidney function. But this test is done along with our lab tests that include
