LP31553-8   Cystatin C
Cystatin C is a miniscule protein that is secreted by all cells containing a nucleus. Cystatin C is usually filtered out of the blood by the kidneys and broken down without being excreted in the urine. Because cystatin C is supposed to be processed by the kidneys, an excess amount of cystatin C could be a sign of kidney disease/malfunction. Cystatin C content in the blood can be tested as an alternative method to testing creatinine in evaluating kidney function. Furthermore, a low blood cystatin C concentration could indicate arthritis, atherosclerosis, aortic aneurism, emphysema, and cancer.

LP32035-5   Creatinine
Creatinine or creatine anhydride, is a breakdown product of creatine phosphate in muscle. The loss of water molecule from creatine results in the formation of creatinine. It is transferred to the kidneys by blood plasma, whereupon it is eliminated by glomular filtration and partial tubular excretion. Creatinine is usually produced at a fairly constant rate and measuring its serum level is a simple test. A rise in blood creatinine levels is observed only with marked damage to functioning nephrons; therefore this test is not suitable for detecting early kidney disease. Creatine and creatinine are metabolized in the kidneys, muscle, liver and pancreas.
