The DRG VZV IgM Enzyme Immunoassay Kit provides materials for the qualitative and semiquantitative determination of IgM-class antibodies to Varicella Zoster Virus in human serum or plasma (EDTA, heparin or citrate plasma). Varicella-Zoster Virus (human herpes virus 3, HHV-3) belongs to the a-subfamily of herpesviridae. The virus particles measure about 145 nm in diameter. The virus is usually transmitted in respiratory secretions, and a single serotype causes varicella (Chickenpox), a highly infectious childhood disease, and zoster (shingles), a neurodermic disease; both diseases are found worldwide.
