I went through with my hair sample testing that I purchased on Groupon for allergytest.co for $75 for the advanced allergy testing for food and non food items as well as the Nutritional deficiency test. I just got my 'results' back today and there is no way this is accurate. I have severe anaphylactic allergies to all tree nuts, all melons, avocado & banana that I carry an Epipen from my medical doctor for. I am also pretty severely allergic to cats. Guess what - not a single one of those are notated on my 'intolerance' list. I have a feeling these are NOT done individually, but just copy and pasted results for everyone that falls for this test.
My results were also all dated 1/11/2017 which can't be correct as today is 1/1/2017. Another item that I don't trust.
The email they sent to tell me they received my sample also has the verbiage "Thank you for your custom." which makes me think this is not North American based an may just be a scam all together.
There is no governing body over these results so they are free to do whatever they like.
Bottom line - don't fall for this junk, go to an actual allergist doctor.
