Reliable testing, consistent results

This was my third time using Intolerance Lab, this time for the 800 Item Sensitivity Test. I'd previously done their Food Intolerance Test and a Vitamin Deficiency Test. Just like before, the process was straightforward – sending in the hair sample was easy. The results came back within the timeframe they estimated, and they were consistent with what I've experienced in the past. It's why I keep coming back; I know what to expect and they deliver every time.

Good test, slow support

I ordered the Food Intolerance Test after hearing about it. The Hair Sample Analysis Kit arrived quickly and the instructions for collecting my sample were clear. The results for the Food Intolerance Test were detailed and seemed to align with some of my suspicions, which was helpful. However, I had a question about one of the items on my report and it took their customer service almost a week to get back to me. The test itself was good for the price, but they could definitely speed up their support response times.

Got my Pet Intolerance Test results

So I got the Pet Intolerance Test for my dog because he was having some tummy troubles. The kit came pretty quick and taking a hair sample from him was actually easier than I thought. Sent it off and got the results back in a decent amount of time. It highlighted a few things that made sense, like chicken. I've started adjusting his diet based on it and he seems a bit better. It felt worth doing.

Thorough report, helpful insights

I decided to try the Comprehensive Health Test to get a broader picture of my well-being. Ordering on the website was simple, and the Hair Sample Analysis Kit arrived in about three days. The instructions for taking the hair sample were very clear, leaving no room for error. Once I sent it back, I received an email confirmation that it was received. The results came back in about ten days, which was within the advertised window. The report itself was quite extensive, covering various sensitivities and deficiencies, and included a basic Elimination Diet Guide. It provided a lot of specific information that has been useful in making dietary adjustments. I didn't need to contact support, so I can't comment on that, but the overall experience from order to results was smooth and informative.

Family Test Package great value

I was looking for a good deal and opted for the Family Test Package. It worked out much cheaper per person than buying individual Food Intolerance Tests. The kit arrived quickly, and each family member had their own clear instructions for taking the hair sample. The results came back within the timeframe stated. For the price we paid, getting multiple detailed reports made it a really good value for money. It was definitely a practical way to test everyone without breaking the bank.

hey, anyone used Intolerance Lab for a pet test? wondering if it's actually worth it for my dog's itching.

C Chris B. 2 months ago
Yeah, I did the pet one for my cat. It helped narrow down some food stuff, but honestly, it's more of a starting point than a magic bullet. Still had to do an elimination diet with her.

I've seen mixed reviews on pet tests generally. Might be better to just talk to your vet first about allergy options, could save you some money in the long run.

Is IntoleranceLab better than YorkTest? Heard about both, not sure which one to go with.

K Kate 2 months ago
I haven't used YorkTest, but IntoleranceLab was easy enough. The report was detailed. I picked them because they did a wider range of items for a similar price point, I think.

From what I gather, they both use hair analysis, so it's a similar method. I'd compare what's included in their packages and the price, sometimes one has sales the other doesn't. Not sure if one is definitively 'better' than the other for everyone.

Thinking of getting the comprehensive test but wondering if there are any discount codes floating around? Always try to save a bit.

A Alex 3 months ago
Check their newsletter signup! I got a 10% off for my first order when I signed up. Or sometimes they have seasonal sales, especially around January or Black Friday.

Yeah, usually 10-20% is what you'll see. Don't think you can stack codes though, so pick the best one you can find. It's just one box at checkout.

How long did it actually take for your results to come back after you sent in the hair sample? Their site says 'x days' but I'm impatient.

M Mark M. 2 months ago
Mine was pretty quick, about a week and a half from when they got the sample. They send you an email when it's ready.

I think mine took closer to two weeks, but it was during a busy period like Christmas. So depends on when you send it in, I guess. You can track it too which is nice.
