Sixteen is more definitive. If it will help you sleep better, do it once more, but no more than that.
Yes, at 0.2 I would believe it is negative, within the bounds of that test.

Terri- thank you again so much you have really helped clarify some things for me- I suppose the timing of my symptoms are just really bad and causing me anxiety.
Two last questions and then I promise I'm finished.
Would you recommend I take the igg test for hsv 1 and 2 one last time at 16 weeks. I've read 10 weeks is fairly accurate but that 12-16 is really more definitive.
And lastly- say my hsv 1 result comes back more around .2 at the 16 week point would you think that was a true negative result?
Thanks again for all your help it has really helped answer my questions and ease some anxiety.
I"m not clear that you need to take a western blot test at this point. What would you do if it was positive for HSV 1 that you aren't doing now? I seriously doubt that your symptoms are due to HSV 1. If it would make you feel clearer, you could do it, but again, not sure what you would do differently. There is a saying in my field that if you don't know what you are going to do with a test result, don't order it.
If, on the other hand, you want to know for some reason like future transmission risks, that might make some sense, but this test won't tell you where you are infected, only IF you are infected.
I have seen people with high negatives that are truly negative, of course. But with HSV 1, we really don't most often confirm high negatives unless we actually suspect new herpes, which I don't in you.
Yes, both a .55 and a .05 could be truly negative.

Dr. Warren- thank you so much for your response. I just wanted to clarify a few things. You said my hsv 1 igg results are high negatives. Do you recommend I get tested by the western blot test? Do you think i should repeat the igg test at 16 weeks? Prior to this I have never had any of the genital symptoms I'm describing except when I had a yeast infection and I have never had a cold sore. If I was positive for hsv 1 would it most likely be oral? I think you're saying its very unlikely I acquired genital herpes from this encounter.
Also- if my negative scores are high then why are there so many ppl who test equivocal that are really negative?
Have you seen people who are truly negative for both hsv 1 and 2 (confirmed by western blot) have high negative igg scores like mine?
And if I read your response correct there is a difference between a .05 and a .55 igg result BUT both ppl could be truly negative it just depends on the test itself- is this correct?
Thank you again so much for all your help.
First of all, many women have yeast that colonizes the genital tract without symptoms and without being a problem, so a positive yeast culture doesn't mean much to me, really.
In terms of the IgG - those are high negatives on your HSV 1 score. The test is not as good for HSV 1 as it is for HSV 2, so you could actually have HSV 1 infection if you were tested by the herpes western blot. However, even if you are truly infected with HSV 1, it is unlikely that these particular symptoms are being caused by HSV 1 genital infection. First, you didn't describe any oral contact, and most often, in my experience, people who have HSV 1 genitally acquired it from receiving oral sex. Not every time but often. This is not the case for you. So you are really more worried about HSV 2. Your scores on that test are very negative. So in other words, I think you are fine in terms of getting herpes from this encounter so far from your testing.
The results on this test can and do vary, depending upon their relationship to a positive and negative control that is built into every test run.
