What is a Cystatin C Test?

The Cystatin C Test is a blood test that measures the levels of cystatin C, a protein produced by all cells in the body. It is primarily used as a marker of kidney function, particularly the glomerular filtration rate (GFR). Unlike traditional markers like creatinine, cystatin C is less influenced by factors like age, muscle mass, and diet, making it a valuable tool in assessing kidney health.
