Food Sensitivity Test

This test kit was relatively easy to use. I didn’t pull my hair intentionally. I simply used the hair that came out when I combed my hair after a shower. It was easy to enroll online and then I just mailed the hair samples into the company. The test verified the food sensitivities I have so I know what to avoid when I eat in the future. The only negative I found was that it was hard to get the hair samples into the little plastic bag. It took multiple tries to get it in, and zip close it up.

Literally saved my husband.

My husband has had life long stomach issues, and I figured maybe if we could cut out foods he's sensitive to it would help him. What I did not expect is that the analysis of his digestive enzymes would help us diagnose a congenital issue that has been the root of his problems.It was easy to submit the test and follow the directions. The results appear accurate and they came back so quickly. This test is worth every penny, especially if you have persistent digestive issues.

Customer Review
couldn't find bag or barcode

This is the first and possibly only part of my review of Premium Food Sensitivity Tests 1000 from Natural Doctors Solutions. The box arrived flattened with the ends forced undone (there was no seal), and when I sat down to do the testing, I did not have the sample bag or any barcode. Because the box ends had opened, it's possible the items might have fallen out of the box when I handled it and I didn't notice. If they remained in the mailer, it has unfortunately been recycled. Definitely, the box should be shrink wrapped or taped to ensure the contents stay inside. However, the directions page and the basic envelope without prepaid postage makes the kit look less than professional. Using "diarrehea" and "gasritis" on the box also do not inspire confidence. If a company can't be bothered to hire a proofreader.... Also, I looked through the website and could not determine which lab handles the hair samples. I've done hair sample testing before and everything looked professional, and I knew what lab was doing it.

Food Sensitivities Advanced Test

I feel uniquely qualified to review this item, so I was happy to get the chance to test it out. For decades, I have battled IBS in one form or another, sometimes mixed. I always knew that food had a big role in my symptoms, but it’s so hard to pinpoint exactly what causes flair ups. About three years ago, after covid caused a huge IBS flair where I felt like I couldn’t eat anything without pain and bloating, I used a home test kit from a company that tests blood samples to help figure out food intolerances. That test saved me!!! It found the biggest culprit, yeast, that I had not been able to narrow down, since yeast and foods made with yeast are EVERYWHERE! The blood test also confirmed my suspicions on other foods that I had guessed were problematic from trial and elimination. Fast forward to this test, which uses only hair samples. I was intrigued by this, because the finger stick of the blood test was a lot for me. It took a while to work up the courage to stick myself to submit the sample. Simply sending in a few hairs? Sign me up! I mailed off the hair samples after registering the kit online. Super simple. Within a few days, I had an email that said my results were ready. There is an information video worth watching that will help you interpret your results. And, let me tell you, my results seem to be right on! They matched the results of the blood test almost exactly. While this test did not explicitly say “yeast” is a trigger item, all of the foods that were listed as trigger items were fermented foods, such as “natto, miso, tempeh, sour cream, mushroom, etc.” It did list soy products as potential triggers, which the blood test did not, but I know I feel a lot better if I avoid soy in all forms. The one thing that this test missed for me, and it might be a limitation of hair testing, is chicken. I absolutely cannot eat chicken without the most unpleasant results. But, since I have not had chicken since my blood test three years ago, it seems likely that my head has no hair left from three years ago. Another thing that you will need to dig into is that the additives are all called by their European “E” number, but you can Google a list of those E numbers and see what they are, for instance, E100 is curcumin. This was pointed out as a trigger for me on this test, and the blood test also showed that I have a sensitivity to curcumin. Bottom line on this food sensitivity test is that I was surprised that a hair sample could yield so many results, and that they were quite accurate in my experience. I 100% recommend getting tested for food sensitivities if you suffer from IBS. Avoiding the foods that your body has trouble with made a world of difference for me. I just want to spread the word in the hopes that all of my fellow IBS sufferers might find some relief like I did.

Easy to use

This is very easy to use and has everything you need. There is no pain involved. Just need a hair sample in the little enclosed bag. The results are fast, within a week. This seems very accurate and a good value. The return envelope does not have a stamp.
