The same thing happened to me this past January. I had 18 months of <0.1 then in Jan. it went to 0.1. I retested 6 weeks later, still 0.1. Then I retested 4 weeks later and it was back to <0.1!
All my test have been the same lab so I don't know what happened. The only thing different was I had a bad sinus infection during that time. Go figure! I don't think it had anything to do with it, must have been just some kind of bump, I hope.
I am due for another test latter June so we'll see. 😳
If I was you, I'd take another test in about
6 weeks. Good luck!
