No, I just wondered if it was a swab from a lesion or a blood antibody test.
Yes, shedding can occur from blisters, regardless of location.
We know about the location of shedding by doing studies where we have people doing daily home swabbing of their genital every day for some extended period of time and coordinating that with a diary of symptoms or not symptoms
You can Google PubMed and enter asymptomatic viral shedding herpes
