Things that helped- and Testing question

Dear Lyme Community,

I was sickened by TBD 3 years ago and tried my medicines and approaches, traditional and non, many to no avail. I have not been active on here because reading about the sickness made me feel very bad. That said, here are some things which have helped me:

IVIG, regular exercise, cutting down refined sugar, magnesium baths, and CBD.

I am thinking that I should retest for TBD, and was wondering if anyone has any advice on whether the tests (I did Igenex) have improved over the last 3 years, and if so which TBD tests they would recommend?

Sending you all my love
