I didn't have the equivocal value on my results, which equivocal would mean they were somehow questionable, so I don't know about that. Each lab has a different scale for the test range. I can tell you that I was "negative" at .4 and 2 months later tested postive at .7. The negative range was <= .4 & positive was .5 or >. I've often wondered why it's negative if you are showing ANY antibodies, ie the .4 or less range.
