Hi Passenger!
Welcome to our community! I'm so glad you found us.
If you haven't yet, it would be helpful for you to start with reading through the thread at the top of the forum titled,"New to Lyme?...Start here!!", as it is packed full of important information, symptom lists, helpful links and pdf's, how to detox when one has these infections, information on probiotics and much more.
And, here's another good place to find helpful detoxing routines:

I'm not familiar with the type of Borrelia test you had done - sorry I can't be of any help with that. Does it have some sort of reference range?
The low CD57 ranges can be caused by a number of things, unfortunately. No one knows yet what all affects the CD57 range, but we do know that if the person has Lyme it can either be high or low and the person can still have Lyme. So it's not a good indicator of a Borrelia infection on it's own.
There are other things you can do though. The one that I like is Horowitz's questionnaire:

Please do continue to ask questions and investigate this possibility. We are here to help as we can!
