Establish of reference range of serum cystatin C among healthy infants and young children in Inner Mongolia area

Objective To apply the latex enhanced immunoturbidimetry to determine serum cystatin C(Cys C) in healthy infants and young children in this area and to establish the reference range. Methods 1 843 healthy infants and young children were detected serum Cys C level by the turbidimetry method and divide into 5 groups according to the age and sex: group I (306 cases), group II (324 cases), group III (380 cases), group IV (401 cases) and group V (432 cases). The differences of serum Cys C levels were compared among various groups for establishing the reference range of serum Cys C in infants. Results The serum Cys C of different genders in the 5 groups had no statistically significant difference (P>0.05). The serum Cys C levels had the statistical difference among the 5 groups (P
