Okay, so first, your gyno is wrong. It's not uncommon for them to be wrong - so many docs don't understand herpes testing.
You should get an index value on the test, but it depends on the lab they use, how they order it, etc. If you're in the US, you can order your own through a number of sites, which I'll include at the end. The ones I include give you an index value. You've obviously done your research because you know about false positives.
There are no supplements that specifically cause outbreaks. There's no food, either - it really is all dependent on the person.
Don't worry about getting a Western Blot yet. That's not hard to get, but it's not inexpensive, either - not even close lol. Just get the IgG, and let's see what that says.
A visual diagnosis of herpes is often unreliable.
A note - the hsv1 IgG misses 30% of infections, and the hsv2 IgG misses 8% of infections. However, given that you've been in a monogamous relationship for 23 years, you aren't really high risk for hsv2. Get your IgG test back from the doctor and see what it says.
Also, the IgG tests only tell you what you have, not where you have it. You can get hsv1 genitally if your partner has oral hsv1 and gives you oral sex. You might also have oral hsv1, and the test will pick up on that.
The IgM is an incredibly unreliable test, and the CDC and all the experts have known for years that it shouldn't be used. Your doctor should know that, too.
Let's just see what the IgG test says, and if you need to, we can go from there.
https://www.stdcheck.com/herpes-1-test.php - can test for just hsv1 or hsv2, or both
https://www.letsgetchecked.com/home-herpes-test/ - must test for hsv1 and hsv2
https://www.healthlabs.com/herpes-tests - can nest for just hsv1 or hsv2, or both
https://www.ultalabtests.com/partners/ultdirect/testing/categories/std/herpes - can nest for just hsv1 or hsv2, or both - do not get the IgM test
All the sites run specials at different times. Google for coupon codes, too.
Also- when I spoke with my doctor on the phone this afternoon I asked if I could get retested if the IGG test does come back positive and she kept saying that if the antibody is detected it’s definitely HSV and there’s no need to retest. I mentioned to her that another doctor a year ago had run an std panel because I thought i had lymph node swelling and then i was told it came back clear. I assumed they tested for herpes but when I went to check it after the gyno telling me she thought what I had was herpes (i thought it was just a pimple and showed it to her as an afterthought), the test didn’t include herpes testing- so i was told they were doing a full std panel then told it was negative assuming that included herpes but it didn’t- they didn’t even tell me that or which exact things it tested for i only found out by going back into the online portal of the lab and looking it up myself. Anyway my gyno told me that they probably didn’t include herpes in the testing and I said yes you’re right they didn’t- and she said I don’t know why they don’t but this test will show. I said what I had read is that it’s not tested for because there are false positives and it’s unreliable but she again assured me that false positives for IGG don’t happen. I’m just concerned if I’m getting wrong or outdated info here… and if the HSV2 IGG test does come back positive i want to know what my next step should be… i’d like to get retested but she seems unwilling to. Is Western Blot more accurate and if so is it available online for a reasonable price?
