Some people just have issues testing with the IgG.
If you're concerned that you're positive, and I'm not at all convinced that you are, or your results would have gone up, you can get a Western Blot test or a BioKit test done to confirm your results.
Equivocal doesn't mean positive - it just means they can't tell. Experts believe that anything under a 3.5 needs to be confirmed because it could be a false positive, and had you gotten a 1.10, there would have been at least an 85% chance that it would be a false positive.
Have you had any symptoms?
You are barely equivocal - that's .90 - 1.10.
If it were me, I'd call it a negative and move on, but it's not me. You can get your doctor to order a Western Blot or BioKit, or you can get a Western Blot through Terri Warren on her site - https://westoverheights.com/getting-a-herpes-western-blot/
