[Question #4914] Confused by HSV Results

27 months ago
History: I had canker sores from childhood but never any cold sores/fever blisters. My former husband of 25 years had cold sores occasionally (once every 5 years) and took Valtrex during outbreaks. Never gave me oral during outbreaks. I don't have any reason to believe I have HSV 1 vaginally. In 2016 had a complete STD panel with results: all negative, with HSV 1 IGG - 6.45, HSV 2 - less than 0.91. Had a relationship with an HSV 2 positive man for six months from November 2016-May 2017. He was diagnosed 20 years ago and hadn't had an episode in 10 years; was not taking anti-virals. We had unprotected intercourse on a number of occasions including a one night event in June 2017. I was tested in April, August, October 2017 with the following results: April - HSV 1 IGG - 5.23, HSV 2 IGG - less than 0.91, August - HSV 1 IGG - 5.76, HSV IGG -  less than 0.91; HSV 1/2 IGM 3.88, October - HSV 2 IGG - less than 0.91. In September 2017 I began a relationship with a man said he was tested - all negative and never any concerns about anything. He had been married for 20 years and no reason to believe he or his ex had anything. Had unprotected intercourse regularly without incident. The first of January I developed an area on my labia that was swollen and sore but no bumps, blisters, scabs. I had cold/flu from mid-December through this period with a bad sore throat but no fever or other symptoms. After a week the area developed a scab and went to see the gyno who said it didn't look like herpes but did a swab anyway (not sure what kind or if matters), no bloodwork for HSV 1 or 2 but everything else was negative. Swab results came back positive for Herpes. Not sure if it's HSV 1 or HSV 2. How do I find out? Should I have another HSV 1 and HSV 2 IGG test? Western Blot? Is it possible I contracted HSV 2 from the man before but never had any signs until now or more likely the person I'm with has it and doesn't realize it? He has gone for testing and waiting for results

The Centers for Disease Control says that every positive herpes swab should be typed. It is highly unfortunate that your physician did not order typing of the swab. Now you are left to wonder what type it is. You could do another IgG at this point, although it might be a bit early since your lesion just showed up around the first of the year. It is certainly possible if you were newly infected with HSV-2 that your antibody test would be positive by now but if it is negative, you would need to repeat it in six or seven weeks to be certain it is negative. In addition, the IgG test Mrs. 8% of infection. You could have HSV one genitally also. It is also possible that you contracted HSV-2 from this most recent partner and his results we'll go a long ways to shaping what you do next.
