What is the value of detecting anti-VZV IgG antibody in CSF to diagnose VZV vasculopathy?
According to a study by Nagel et al. (2011), detecting anti-VZV IgG antibody in CSF can be valuable in diagnosing VZV vasculopathy. This study found that the presence of anti-VZV IgG antibody in CSF was associated with a higher likelihood of VZV vasculopathy. In addition, this antibody was found to be more sensitive and specific for identifying VZV vasculopathy compared to other markers such as anti-VZV IgM antibody. Thus, detecting anti-VZV IgG antibody in CSF can be a useful tool for diagnosing VZV vasculopathy.
