    Cystatin C is a blood marker used to assess kidney function. Unlike creatinine, it is less influenced by muscle mass, age, or gender, making it a more sensitive indicator of early changes in kidney filtration (GFR). It is often used for more accurate renal assessment, especially in patients where creatinine may not fully reflect kidney health.
