IGG Herpes Blood Test?

Hello all, I have a lot of anxiety when it comes to any stds and get myself tested very very often. Lately my main concern is Herpes- Ive gotten fissures my whole life and doctors have said it was nothing to worry about and have been blood tested about 4-5 times, never swabbed bc the fissures heal within a day or two. My most recent test, which was last week, I noticed the number increased? What does this mean? I’m a little worried now and its definitely making my anxiety bad again. Any help is appreciated.
