HERPES SIMPLEX VIRUS (HSV) 1/2 GLYCOPROTEIN G-SPECIFIC, IgG BY ELISA

Mnemonic

HSVG

Synonym

HSV - HSV glycoprotein G type 1 and 2 - HSV typing 1 and 2

Guidelines

Qualitative measurement of Herpes simplex antibodies. Almost all recurrent genital herpes cases are caused by HSV type 2, yet HSV type 1, the causative agent of orolabial herpes, causes up to 30% of first episode genital herpes.
