Cystatin C

Alias: N/A

Discipline: Clinical Chemistry

Test information: Please note this test is for Renal and the Paediatric teams only. It is produced by all nucleated cells, is freely filtered at the glomerulus, almost completely reabsorbed, degraded and not secreted by the proximal renal tubular cells. Thus it fits the criteria for a good marker of the glomerular filtration rate (GFR). The plasma concentration of Cystatin C is almost exclusively determined by the GFR.
