At least half of all people acquire HSV1, so such exposures are nothing special or worrisome. The HSV blood test takes up to 12 weeks to become positive, and is never a way to diagnose newly acquired herpes. In a family situation like this, blood tests should not be necessary. If there are typical cold sore outbreaks, that's enough to be sure of the diagnosis. Or see a doctor for confirmation.

Your family likely has been exposed to your virus many times. More than half of the "normal" population has been infected with HSV 1 and the only manifestation they have are occasional cold sores. Testing for HSV 1 is not warranted.
