What is Cystatin C (Cystatin C)?
Cystatin C is measured as part of a kidney function panel. Your Cystatin C is normal, suggesting good kidney filtration.
What does a high Cystatin C mean?
Your Cystatin C is elevated, which suggests reduced kidney filtration. It's a sensitive kidney marker, sometimes used alongside creatinine and eGFR.
