Peace Please,
I agree that co-infection testing is not reliable when you get a negative result. However, I don't know why any LLMD would say you could not rely on a positive test from Fry labs. I have not heard negative things about
the lab. Maybe the doctor was not ILADS trained.
In fact, Protomyxzoa Rheumatica, also know as the Fry bug or FL 1953 as Girlie mentioned, can cause bladder issues. So can Bartonella. Check out:

these issues. We can help you find another doctor if you would like.
You can also do searches here on bladder issues. There are a number of helpful threads.
