The aim of this study was to determine the reference values for serum cystatin C (CysC) with a particular focus on the effect of aging.
The study was performed on a consecutive series of subjects (258 men and 396 women). Laboratory parameters and a detailed personal and family medical history were collected.
CysC showed a significant correlation with age in both sexes, which was confirmed with multivariate linear regression after adjustment for SCr (serum creatinine). Age-related reference intervals were established for cystatin C (<45 years, <0.95 mg/L and >45 years, <1.20 mg/L).
The use of CysC reference values adjusted for age should be carefully taken into consideration.
本研究旨在确定血清胱抑素C（CysC）的参考值，特别关注衰老的影响。
对一系列连续的受试者（258名男性和396名女性）进行了研究。收集了实验室参数以及详细的个人和家族病史。
CysC在两性中均与年龄呈显著相关性，在调整血清肌酐（SCr）后通过多元线性回归得到证实。建立了与年龄相关的胱抑素C参考区间（<45岁，<0.95mg/L；>45岁，<1.20mg/L）。
应谨慎考虑使用根据年龄调整的CysC参考值。
