Worth the investment for peace of mind

I was hesitant to spend money on one of these tests, but I decided to go for the Prime Food Intolerance Test during a seasonal sale. The introductory offer made it feel like a worthwhile investment. The kit came fast, and the process was mess-free. When the results arrived, they confirmed some suspicions and also highlighted a few unexpected sensitivities. It felt good to finally have some concrete information to work with. Definitely worth the price I paid for the peace of mind and direction it gave me.

Detailed insights, great support

I purchased the Health and Wellbeing Test a few weeks ago. The ordering process on the website was straightforward, and the kit arrived within 3 days. The instructions for collecting the hair sample were very clear, and I appreciated the pre-paid envelope for sending it back. I received my detailed report via email exactly 7 days after they confirmed receipt of my sample. The report itself was extensive, breaking down different categories and explaining what each sensitivity meant. I had a question about one of the items, so I used their online chat support, and the representative was very knowledgeable and helpful, clarifying my concern within minutes. It really helped me understand what changes I needed to make.

Consistent results, easy process

I've used Test Your Intolerance several times now, mostly for the Individual Sensitivity Test. This last one was just as smooth as the others. Sent in my sample, got the results back in about a week. The reports are always clear and easy to understand, which is why I keep coming back. They're reliable.

Good value, minor snag

I ordered the Allergy and Intolerance Combined Test. The test kit arrived quickly and was easy to use; instructions were super clear. The results were quite comprehensive and gave me some good insights. My only minor issue was that tracking the return sample felt a little vague after it left my hands. But overall, it was a good experience and felt like a fair price for the info I got.

Super helpful for my dog!

So I got the Dog Allergy Test for my pug, Buster, 'cause he was always scratching. The kit was surprisingly simple to use, just a little hair sample. The results came back pretty quick and actually pointed to a few things I never would've guessed. Buster's doing way better now that we adjusted his food. It just felt really good to finally get some answers for him.

Does anyone know if they ship to the US? I'm in New York and want to get a kit.

J Jason W. 4 weeks ago
Yep, they do! I'm in California and got my kit delivered here no problem. Shipping was pretty fast too.

Can confirm, they ship to the USA. Just make sure you select the correct region when you order, if there's an option, though I think it's usually automatic based on your IP.

Has anyone done the Prime Food Intolerance Test? Does it cover a good range of things or should I just go for one of the bigger bundles?

L Leah 1 day ago
The Prime one covers a decent amount of common stuff, like a few hundred items I think? If you're just starting out and not sure what your triggers are, it's a good place to begin.

I did the Prime and it was enough for me. My sister did the 'Allergy and Intolerance Combined' test though because she had a wider range of symptoms and wanted to cover all her bases. Depends on how many things you suspect.

Thinking of getting the Family Sensitivity Test but also saw a newsletter sign-up discount. Can I combine those two codes?

D Danielle L. 4 days ago
From my experience with other online stores, it's usually one discount code per order. So you'd probably have to pick between the family bundle savings or the newsletter one.

I tried to use a student discount with a seasonal sale once and it didn't work. I think their system only lets you use one code at checkout. The family pack discount is usually already applied as part of the price I think, so that wouldn't be a separate code anyway.

Hey, wondering how accurate these home tests really are. I've heard mixed things about at-home sensitivity tests in general.

E Eric S. 2 weeks ago
Yeah, I had similar concerns. I used them for a suspected dairy issue and the results pretty much confirmed what I was already feeling. It's not like a doctor's diagnosis, but it definitely gave me a good starting point for changes.

I think they're good for pointing you in the right direction. My friend used a different company and said it was a bit vague, but this one for me was pretty detailed with the report.
