Good value for a SIBO test

As a first-time buyer, I was looking for the most cost-effective way to get a SIBO test. I found a new customer discount which helped bring the price of the SIBO Breath Test Kit down a bit. The total cost, including shipping, felt like a good deal compared to other options I researched. The kit had all the necessary components, and the instructions were clear enough to follow without any issues. While it wasn't the absolute cheapest, the value for the money, considering the quality and comprehensive results, made it a worthwhile purchase for me. I'm happy with what I paid for.

So easy to use!

I got the Fructose Intolerance Test Kit and it was fantastic! Everything was super clear, and I got my results pretty fast. I'm so glad I found them; it made understanding my issues so much simpler. Definitely shopping here again!

Smooth process, clear results

I ordered the Combined SIBO Test kit after reading up on a few different providers. The ordering process on the website was straightforward, and I received a confirmation email right away. The kit arrived in about 6 days, which felt reasonable coming from the UK. Instructions for the prep diet and sample collection were very clear, easy to follow. I had a quick question about one of the vials, and customer support responded within a few hours with a helpful answer. Sending the samples back was simple with the pre-paid envelope. My results were available online about 8 days after they received my samples, and the clinical interpretation was quite detailed, making it easy to understand what the numbers meant for my gut health. Overall, a very professional and user-friendly experience from start to finish.

Decent test, some delays

I purchased the Lactose Intolerance Test Kit to finally get some answers. The kit itself was well-packaged and the instructions were easy to follow. Shipping took about a week to get to me, which was a little slower than I hoped, but not terrible. The sample return process was smooth, and I got my results back in about 9 days after they confirmed receipt. The interpretation was clear and helpful. My only minor gripe was that I didn't receive an update for a few days after I sent my samples back, so I wasn't sure if they had arrived. A bit more communication on that front would be nice. Overall, a good service for the price.

Thinking of getting a couple of tests, maybe the SIBO and a lactose one. Do they do any kind of discount if you buy more than one test at a time?

D Daniel Nguyen 1 month ago
Yeah, they usually have bundle deals. I got a pretty good saving when I bought my SIBO and fructose tests together.

Hey, thinking about getting a SIBO test kit. Anyone know how long it usually takes to get the results back once you send it in?

K Kevin Garcia 1 week ago
Mine was pretty quick actually, like 3-5 days after they got my samples. They send you an email once they receive them too.

J Josh Sanchez 1 week ago
Yeah, I think mine was about a week. It wasn't super long, but depends on when you mail it back I guess.

Just wondering, do you need a doctor's referral to order one of these kits, or can I just buy it myself?

J Jeff J. 1 week ago
Nope, you can just order it straight up. No doctor needed.

How do you actually send the samples back? Is it like a pre-paid envelope or something?

I Ian 1 week ago
They give you everything you need. It's a pre-addressed, pre-paid return envelope, super easy.

Yep, just pop it in the postbox with their included packaging. No extra cost to send it back.
