cystatin C (cystatinC)
Last reviewed 08/2021
- Cystatin C
- is a single chain basic protein with low molecular weight (13 kD) produced
by all nucleated human cells, whose circulating concentrations can be
easily determined by an automated particle-enhanced immunoturbidimetric
method
- mainly filtrated by the kidney
- other factors affecting the production of Cystatin C include the use of systemic glucocorticoids and thyroid dysfunction
- Cystatin C and microalbuminuria are considered early markers of kidney damage
- Cystatin C could be affected by changes in body composition. Indeed, fat-free mass, a parameter inversely related to age, affects CysC level, and in older patients with chronic kidney disease CysC-based GFR estimation improves when fat-free mass is taken into account (1)
