Can you test negative for herpes without an outbreak?

Experiencing these symptoms is referred to as having a first herpes “outbreak” or episode.
How accurate are blood tests for HSV-2?
Herpes blood tests, also known as herpes serologic tests, are available for both types of the virus (HSV-1 and HSV-2).
