Yes, even if someone has HSV-1 antibodies in their blood test (meaning they have HSV-1 somewhere in their body), they can still potentially contract HSV-1 in a different location, such as the genital area. However, having existing HSV-1 antibodies may provide some level of protection against getting infected in a new location, though this protection isn't complete.

It's important to understand that:
1. Most people with HSV-1 have it orally (cold sores)
2. Having HSV-1 antibodies provides some, but not complete, protection against getting it in another location
3. Transmission is still possible, especially during outbreaks

To minimize transmission risk, consider:
- Using protection during intimate contact
- Avoiding intimate contact during outbreaks
- Having open discussions with your partner

For the most accurate assessment of your specific situation, please consult with a healthcare provider who can review your complete medical history and provide personalized guidance.
