Sorry to hear your trouble with the condition.
I am a microbiologist and have some concerns about your intent.
As of 2013, culturing and identifying Borrelia burgdorferi is not an easy task even in a professional lab (that may be why it took you 3 trips):https://www.ncbi.nlm.nih.gov/pmc/articl ... po=76.1682https://www.cdc.gov/mmwr/preview/mmwrht ... mm6315a4_x
Most bacteria ID requires professional lab equipments and some bacteriology knowledge.
You may try to self-monitor your disease severity, but a clinician may not be willing to accept your own test results or make treatment changes based on that.
Edit: I did not suggest this, but your brother may or may not be willing to prescribe medications for you if you have to go that route.
Thanks for the input.
I do have to clarify some points here.
I am really not going to be self diagnosing and self medicating,
but looking to back up in my mind whatever is found or not by the labs.
I don't intend to present any findings to anyone other than my brother if needed, just for self satisfaction.
I don't expect or intend to have my brother pass out scripts for anything, just x-check any findings or not by me.
Yes I could have him prescribe anything I would need if asked, never have though,
he is retiring in two years but is keeping his license.
He spent almost a decade in the distant past working for the Worcester foundation for experimental biology before deciding to go into private practice.
I have a long way to go in learning, if I live that long.
My lab won't be complete for about 6 months, I already have a lot of equipment and consumables I did not list.
I also have access to a complete bio lab and an electron microscope at U-mass after hours if I need it.
Over three decades I have built to include the engineering custom lab equipment for research labs of national recognition.
Originally I got my first scope to test my well water for various things, but ended up with town water so the scope has sat for the last 15 years.
