Cystatin C and α₁-ACT in patient cerebrospinal fluid.

CSF levels of cystatin C and α1-ACT. Levels of cystatin C and α1-ACT were measured in patient CSF by ELISA and expressed as quantity per ml fluid or relative to total CSF protein. Values from sCJD patient CSF were compared to values obtained from CSF of both AD patients and healthy control groups of comparable age and gender distribution within groups (control group A). Since vCJD is typically prevalent in patients of a younger age, values for vCJD CSF were compared to those obtained from patients of comparable age (control group B).
