33863-2 Cystatin C [Mass/volume] in Serum or Plasma

Part Descriptions

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.

Change Reason
Release 2.73: METHOD_TYP: Updated method using the CKD-EPI Cystatin C equation (http://ckdepi.org/equations/cystatin-c-based-equations/); Previous Releases: System changed from "Ser/Plas" to "Ser/Plas/Bld". According to the National Kidney Disease Education Program (NKDEP) Lab Working Group, estimated GFR may be calculated based on blood, serum, or plasma creatinine levels. Whole blood methods are calibrated to be the same as serum/plasma methods, and the isotope dilution mass spectrometry (IDMS) reference measurement procedure is the same for whole blood, serum, and plasma.
