Reference Values

< 1.00 S/CO = Negative 
A result below 1.00 S/CO may indicate the absence, or a level of IgG antibodies to VZV below the threshold. 
≥ 1.00 S/CO = Positive 
A result above or equal to 1.00 S/CO generally indicates exposure of the subject to VZV. 
 
A negative result for IgG antibodies to VZV generally indicates that immunity has not been acquired but does not exclude the possibility of acute VZV infection, because the infection may be in its very early stage and the patient may be still unable to synthesize VZV specific antibodies, or the antibodies may be present in undetectable levels. 
 
A positive result for IgG antibodies to VZV generally indicates exposure to the pathogen or administration of immunoglobulins, but it is no indication of active infection or stage of disease.
