Abstract:
OBJECTIVE:The aim of this study was to determine the adult reference values for cystatin C (CysC) and to evaluate their consistence with those reported in the literature. DESIGN AND METHODS:CysC was analyzed in a consecutive series of subjects (100 males and 100 females) by a nephelometric immunoassay. Medline was searched for CysC reference values. RESULTS:CysC reference intervals showed 4-11% of variation at the upper limit. The mean upper limit was =1.0 mg/L of CysC. CONCLUSION:Nephelometric CysC reference intervals are consistent among different populations.
