That's a really practical question—and it highlights something important: **serology alone can't tell you location**.
Here's the reality: IgG antibody tests (positive/negative) only confirm you've been exposed to HSV-1 or HSV-2 at *some point*. They don't reveal where the virus established itself or where future outbreaks will occur.
**What actually determines location:**
- **Clinical history** — Where did your first outbreak happen? That's typically where the virus "lives" (though not always exclusively)
- **Viral culture or PCR during an outbreak** — Testing fluid from an active lesion can confirm HSV type *and* location simultaneously
- **Type-specific serology + symptom pattern** — If you're HSV-2 positive and had genital symptoms, that's strong evidence of genital infection. HSV-1 oral is common, but HSV-1 can also be genital, and vice versa
**The gap you've identified is real:** A positive IgG without outbreak history leaves ambiguity. Some people are asymptomatic shedders or have had such mild symptoms they didn't notice.
**Next steps:** If you're trying to understand your specific situation, discuss with a healthcare provider who can review your symptom history (if any), consider type-specific testing if available, or recommend viral testing *if* an outbreak occurs. This context matters for your own awareness and any future conversations about sexual health.
