My doctor won't even test mine right now, and he does use it to gauge progress............lol. Mine was under 20 before treatment. I think it's normal for CD-57's to fluctuate. If you are someone who had a low number, it should rise when Lyme is under control. I have heard that they drop upon treatment for babesia. Perhaps that is an explanation?
