I would say yes, but call a GI clinic and ask. It may be covered by insurance that way. Or atleast they can prescribe the test kit for in home and they receive the results.
I was seeing a holistic Doctor who doesn’t take insurance, but he carries them in his in house pharmacy and I got a slight discount. He treated me with probiotics but recommended I see my Primary Doc with the sepsis results. He did bloodwork and the sepsis had escaped my gut and into my blood stream! It caused very nasty skin lesions on my feet and buttocks. So yes, the test was expensive but probably saved my life (and corrected the constipation. )And general health.
I forgot to mention in my first post that bad gut biome was found in longcovid cadavers initially. Then others like me also found scary bacteria.
It was my first real step in improving my LC health.
Gut biome testing has recently gotten a lot of positive attention.
Good luck!
