Positive blood test

I started having symptoms of herpes about 2 weeks after unprotected sex with a new partner. I was diagnosed by a viral culture of a lesion. I had the doctor do a blood test a few days later (it would have been 2 1/2 weeks at that point) and it was positive. My doctor said that could mean it's an old infection, or that my body is already making the antibodies. How likely is it that that's the case? I am inclined to believe this is my first exposure as the timeline and symptoms are pretty textbook. I have never had anything like this symptom-wise, and it seems quite severe which makes me think this is the primary outbreak. I haven't been with anyone else in almost 6 months. I have been healthier and happier in the last few months than I have been in years, so if I did already have it it seems weird to have an outbreak now.

I should add that I am negative for HSV1 and positive for HSV2.

I feel you. I am in a very similar boat. Very surprised to have first symptoms at the most happy, low stress time of my life but a high IGG value on a lab test.  Would love to hear the answer from the experts.

I'm sorry you are going through this!

If you have had a high value (say > 5) on an IgG antibodies type specific for HSV2, then there would be little doubt you were not recently infected but potentially for years.

Any other test such as IgM is not reliable. Any value less than 3.5 may be a false positive and would not indicate a long term infection necessarily.

Further, 2 weeks is long time, so if you had just a single sore patch then this would suggest a longer term infection. Most recent infections result in multiple sores within a week.

Thank you! I have a few sores, and am now experiencing a second round of them even though I've been on acyclovir for over a week. I also woke up feeling quite ill the day I was diagnosed as well as the next day, and have bad leg and lower back pain.

What actual blood test did you have? What were the exact results?

I just got a hsv2 1.7 and positive for HSV1.. What is the best way to recheck? No symptoms.

My doctors office is strangely ignorant and apathetic when it comes to this,they did not even tell me which test I got nor did they give me the actual results just that it was positive for the antibodies.  I was the one to bring up the blood test in the first place .  However they usually mail me a copy of the information as well so I am hoping that that will have what I need. If it doesn't then I will call them and harass them until they give me that information.

My partner and I had sex the morning of my outbreak (I didn't notice the sores until hours later, and I had used Monistat the day before thinking I had a yeast infection and that relieved the itching). He is waiting to get in to be tested, but so far doesn't seem to have any symptoms. Unless the timing is a huge coincidence and this is a super delayed primary outbreak, I am inclined to believe I got it from him. It's been 10 days since our last sexual contact.
