I'm so sorry you have to go through all this uncertainty and questioning! I don't know much about
this test yet - is it a blood culture? What we do know about
these bacteria is that they're good at hiding, so maybe they just weren't detectable. Maybe they're in cyst form. Maybe in biofilms. So many maybes, I know.
What has your doctor said about this? And is your current treatment helping? At the end of the day as much as we want to know what's really going on, what matters is making it go away.
