CYSTATIN C
What does CYSTATIN C measure?
The Cystatin C test measures the level of cystatin C, a protein produced by the body and removed from the blood by the kidneys. It may be used to help assess kidney filtration function and estimate glomerular filtration rate, particularly when creatinine-based assessment may be less reliable. Healthcare professionals may order it to evaluate possible changes in kidney function or to monitor known kidney concerns.
