Test was very easy to use. As others have said the diet is the hard part. Received text message when test was received at their lab and again after the results had been sent to my doctor. Would highly recommend the at home test. We're glad you had a good experience with us, ******. Thank you for your review!

The at home testing kit was easy to use. The diet was the hard part. Not being able to eat anything with flavor is hard. I drank more water and ate eggs, but I did break for chicken. I liked that I could decide the best tone to use the kit and make it work for my schedule. Directions were simple although I forgot to sign my form.

******** customer service if youd call it that . I tried calling multiple times to ask questions before taking the test and no one answered the phones . Just terrible I wouldnt recommend a company that Cant even answer the phone . I wander if they even processed my test correctly since they cant even answer the phone . 

Business response:

Good morning, *****, I apologize for the difficulty in reaching us. We have been a bit short staffed on the phones and have been working diligently to get caught up on correspondence. I do see that your voicemail was returned, but we also had to leave a message for you. Your test kit was processed by our lab team and reported to your ordering physician on 6/5/2025.

SIBO testing that I had done on May 13 was a very simple process, instructions were easy to follow and delivery was all a very efficient endeavor. Results were relayed to myself approximately a week later and therefore could do the proper follow up. All in all a very easy procedure
