They have no idea what all contributes to the CD 57 - unless new research is out that I'm unaware of - so it's not accurate.
There are severely ill Lyme patients that have a very high CD57 and some patients that hardly have any symptoms that have very, very low CD57 tests - so it's not good to help determine severity of the infections either.
It's just one more thing people can do to try to convince the insurance company or doctor that they have Lyme, but by itself, it's not of much value as it doesn't tell us if we have Lyme, or what stage we are in.
