Thanks for your response!
Older tests had more false positives for various reasons, however the false positives still exist around 5% of times the test is applied I believe.
My previous thinking still stands, I reckon you're negative.
The first three times were in 2009. The latest test was in 2013.
At the 3.5 level, 95% or more people will truly have the virus. Most people with the infection test over 5.
How many years are we talking since that previous testing? There may have been some iterative improvements in the testing since that time.
Thank you, this is quite helpful! Unfortunately the records from the second test don't indicate what procedure was used.
The latest Herpeselect result sheet said that >=1.1 is a positive result. The second test was 2.21 for IgG, so that sounds it was quite a bit over that. Up to what value is the test considered a low positive (and how would that have to be confirmed)?
Thanks again!
The original IgG positive results, assuming it was Herpeselect as well, is a low positive and can be caused by stuff in your blood that reacts with the testing plate. Regardless of whether Lyme's bacteria was at play, confirmatory testing was always required, that level was not confirmation of infection.
The latest testing that reveals a negative is therefore quite credible as you never had a diagnosis in the first instance. I also assume that you have had no particular symptoms of concern.
A Westernblot would provide you with even more confidence but if it were me, I'd be comfortable I was negative for the virus.
