Hydrogen Breath Test

Hey there!

So, like the title says, I’m trying to figure out if it’s even possible to get this specific test done—and if so, where? Do American doctors even know what SIBO is, or am I totally out of luck here? Can you actually find someone in the States who can run a test for it?
If anyone knows anything, please hit me up. Everything I dig up online is just in English or filled with stories from people living abroad.

In the US, you can get an exhaled breath test, but they just don't offer them here.

Does anyone happen to know if this is available anywhere? Maybe somewhere nearby—or even a bit further out, I suppose?
