Also known as: Herpes-1 and 2, HSV Types 1- and 2-Specific Antibodies, IgG, HSV-1 and 2.

Herpes simplex viruses which are more commonly known as herpes, are categorized into two types: herpes type 1 (HSV-1, or oral herpes) and herpes type 2 (HSV-2, or genital herpes). Herpes type 1 most commonly causes sores around the mouth and lips (sometimes called fever blisters or cold sores). HSV-1 may cause genital herpes, but most cases of genital herpes are caused by herpes type 2. In HSV-2, the infected person may have sores around the rectum or genitals. Although HSV-2 sores may occur in other locations, these sores generally are found below the waist.
