Great value, clear savings

I was looking for a good deal on a breath test, so I checked GI Cognition. I saw they had a new customer discount for 10% off, which I used on the Lactulose Breath Test Kit. The final price felt fair, especially compared to other places. Shipping was free, which saved me a few dollars too. The kit arrived in good time, and the instructions were clear enough. For someone trying to save money but still get a quality test, this was a good option. Glad I found them.

Reliable testing, always return

This was my third time ordering from GI Cognition. I got the Re-test Kit for SIBO Recovery Monitoring. Like before, the kit came quickly, maybe 4 days to my house in Florida. The process is consistent; instructions haven't changed much, which is good when you're used to it. I appreciate that they're reliable. My previous results were accurate and helped my doctor. That's why I keep coming back. Never had issues with returning samples or getting results. It's just a dependable service for these types of tests.

Super helpful for my gut!

I got the Combined SIBO Test and it was so helpful! Everything was straightforward. The kit got to me in less than a week. Doing the test at home was really easy and convenient. I used their Digestive Health Consultation after getting my results and it made such a difference. I'm telling all my friends who have gut issues to check them out. Definitely shopping here again!

Good test, decent support

I ordered the Intolerance Screening Bundle last month. The kit arrived in about 6 business days, which was fine. The instructions for the Lactose and Fructose tests were easy to follow. I had a question about the preparation diet for the SIBO test and used their online chat. Response was quick, maybe 15 minutes. Sent my samples back, tracking worked. Results came back within the 10 days they quoted. The Clinical Interpretation Service was useful, helped me understand the findings. Packaging was sturdy. Overall, a solid experience for home testing.

Do I need a doctor to order these tests? Or can I just buy one and do it myself?

J Jared 1 month ago
Nah, you don't need a doctor's note for these. You just buy it directly from their site, that's what I did for my fructose test.

Nope, no referral needed. That's one of the perks, you can just grab a kit and get it done. The results come with a pretty detailed explanation too.

Hey, thinking of getting one of the SIBO kits. How long does it actually take to get the results back once I send it in?

B Ben Z. 2 months ago
Mine was pretty quick actually. I think it was less than a week from when they got my sample back until I had the report in my inbox. Definitely not a long wait.

Yeah, same experience. I'd say about 5-7 days after they receive your sample. They send an email when they get it, which is nice.
