Hi
Thanks for your query at HCM.
I understand your concern and situation. If swab test shows positive results i would suggest you to take treatment without doubts. HSV infection is caused by HSV-1, an IgG blood test is only 91% sensitive so it can miss almost 1 out of every 10 cases. You may take a retest after 12 weeks or get a more specific test done Western blotting or PCR with 93-95% sensitivity.
Take care
Hope I answered your query
